    RSGB GB2RS News Bulletin for 22nd December 2024

    GB2RS News

    Sunday the 22nd of December

    The news headlines:

    • The RSGB is looking for a new Lecture Coordinator
    • YOTA Month draws to a close but is still busy on the air
    • The first RSGB Tonight@8 webinar of 2025 focuses on GB2RS

    The RSGB facilitates just over 60 lectures each year in a mixture of in-person, hybrid and remote formats. 50 of these are at the RSGB Convention and 11 are delivered through the livestreamed Tonight@8 webinar programme of events. This set of presentations aims to cover a wide mix of amateur radio-related subjects, across all depths of amateur radio experience and knowledge. They are watched and admired by RSGB members and non-members across the world. The RSGB Lecture Coordinator is part of the Tonight@8 and Convention teams. Its recent Lecture Coordinator Keith Hotchkiss, G0FEA has stepped back to focus on his professional commitments, so the RSGB is looking for someone new for this volunteer role. The right person will be proactive and collaborative, bringing ideas for presentations that educate and inspire radio amateurs to try something new, learn more about interesting topics and expand their knowledge of amateur radio. They will lead the invitation and scheduling process for Tonight@8 webinars and contribute to the decisions about Convention presentations. They will also be the main contact with Convention presenters, inviting them to speak, updating the speaker project plan and helping to create a balanced programme. Reporting to the Convention Chair, the Lecture Coordinator would be a member of the RSGB Convention team but would not be required to take responsibility for organising and managing other aspects of the event. If you’re interested in the role or would like to find out more, please contact the RSGB General Manager Steve Thomas, M1ACB via [email protected]

    Youngsters on the Air Month is nearly at a close. It has been filled with some brilliant activity from young people using special callsign GB24YOTA. Thank you to everyone involved, from supervising young amateurs to making contact with them on the air. Before the year ends, we still have some activity using GB24YOTA, so please continue to listen out. Tomorrow, Monday the 23rd of December, Hilderstone Radio Society will be back on the air as it hosts the callsign for a final time this month. On Sunday the 29th of December, Bushvalley Amateur Radio Club in Northern Ireland will be operating GB24YOTA, followed by Marlborough Scouts on Monday the 30th of December. If you have been involved with Youngsters on the Air Month and would like your activity to be in a special RadCom feature, email your photos and a short report to [email protected]  as soon as possible.

    The first RSGB Tonight@8 webinar of 2025 will be live on Monday the 6th of January. The presentation is all about the RSGB’s GB2RS News service which will be celebrating its 70th anniversary next year. A team of people will contribute to the live presentation and will give you a behind-the-scenes insight into how the script is compiled, as well as a newsreader’s perspective of the weekly broadcast. They’ll share details of the plans being put in place for the anniversary and explain how you can get involved. The team will also consider GB2RS in the modern media environment and how new technologies in amateur radio are being embraced. Find out more about this fascinating discussion and the presenters by going to rsgb.org/webinars  Watch the presentation live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat.

    The RSGB will be releasing four new presentations from its 2024 Convention over the festive season. If you’d like to be the first to hear about new releases as soon as they are available, go to youtube.com/theRSGB and subscribe to receive notifications.

    Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 19th of December 2024.

    The last week was a little more disturbed than usual and we had a Kp index that hit 5.33. An enhanced solar wind stream contributed to active geomagnetic conditions and an interplanetary shockwave, that swept past Earth at 0519UTC on the 17th of December, caused minor G1 geomagnetic storming.

    A far-sided halo coronal mass ejection event also occurred later on the 17th of December at 1600UTC although this was not directed towards Earth.

    This shows that the Sun is still very active, and we should not be surprised if we experience more solar flares and CMEs.

    The solar flux index stayed in the 160s and 170s and we should keep an eye on active region 3927, which is currently turning to be Earth-facing and has already been the source of some C-class solar flares.

    Next week NOAA predicts that the solar flux index may rise slightly to be in the 180s. The largest Kp index forecast is 2, which probably means that NOAA is unsure about what will actually happen.

    We are pleased to report that OF9X is once again on the air from the land of Santa Claus in Lapland. Up to 16 operators will operate Santa Radio on the 160 to 6m bands using CW, SSB, RTTY, FT4 and FT8. They have already been spotted on the 30 and 20m bands using CW and on the 12 and 17m bands using RTTY. So, there is plenty of scope to work them.

    According to the prediction program Proppy, paths to Lapland should be open on 14MHz from 0800UTC to 1800UTC. On 28MHz, expect them to be open from 0930 to 1500UTC. The 80 and 40m bands should be mainly open during the hours of darkness.

    As always, across the Christmas period, we recommend that you use solarham.com and propquest.co.uk for real-time updates on solar and ionospheric conditions.

    And now the VHF and up propagation news from G3YLA and G4BAO.

    Last week ended in a colder unsettled period of weather with strong north-westerly winds and spells of rain or showers.

    The air is sufficiently cold that some snow is possible over northern hills. This is potentially good news for rain or snow scatter, especially off fast-moving showers down the coastal fringes of the UK. 

    Although the nearest high remains near the Azores to begin with, it slowly migrates east to France and, by Christmas, to central Europe. This will bring high pressure and possibly Tropo onto Santa’s list from Christmas Eve onwards. Look for patches of misty low cloud or fog for the best conditions.

    As usual, check for other modes. Meteor scatter and aurora are both worth consideration and this is a prime time for out-of-season Sporadic-E between now and about mid-January. 

    One of the helpful aspects of looking for winter Sporadic-E is that quite often the jet streams are significantly stronger than in the more traditional summer Sporadic-E season. Jet streams are a good source of turbulence that can eventually propagate up to the E region to make Sporadic-E propagation.

    Jet streams are shown on upper air charts and can be a good geographical guide to Sporadic-E prospects in the summer and should therefore be similarly consulted for these winter events.

    In this case, they tell us that the first half of the coming week, up to Christmas Day, is well set up with a northerly jet stream over central Europe and, more importantly, crossing the Alps. So, a second mode goes on to Santa’s list.

    Check the VHF Cluster’s Sporadic-E graphs at propquest.co.uk for early signs of activity, particularly for paths to the southeast into Italy and the Balkans.

    The Moon started this weekend with positive declination but goes negative late today, the 22nd. Path losses are at their highest due to apogee on Christmas Eve. 144MHz sky noise is high until Wednesday, including near-eclipse conditions all day on Monday.

    That’s it for this year. How about making a New Year’s resolution to try a new mode? Maybe use SSB or CW on VHF now and again and put out lots of CQ calls in 2025!

    And that’s all from the propagation team this week.

    RSGB GB2RS News Bulletin for 15th December 2024

    GB2RS News

    Sunday the 15th of December

    The news headlines:

    • The RSGB 2025 election nominations process is open
    • The Society is advertising for a new Convention Chair
    • YOTA Month is busy this week with more callsign hosts to listen out for

    The RSGB 2025 elections process has begun, and nominations are open for a range of volunteer roles. The RSGB’s President John McCullagh, GI4BWM will reach the end of his second year as President at the AGM and so will stand down. There are also two Elected Board Director vacancies. The Board is looking for people with specific skills to fill these roles. The current President is one of the few at the Board level with extensive experience in spectrum matters and negotiating with the authorities, so that skills gap needs to be filled. Outreach has been an important focus over the last year for the Society, and it would like to support the current activities and expand on them. These developments will include encouraging practical skills amongst the amateur radio community and building links with other organisations. Building those relationships will require someone with drive and determination but also tact and diplomacy. There are eight posts available for RSGB Regional Representatives, ranging from Region 1 in Scotland to Region 11 in the southwest. For more details about the roles as well as application forms and candidate packs, go to the RSGB website at rsgb.org/election

    The RSGB has been developing its Convention over recent years to suit the changing needs of the amateur radio community. From a face-to-face meeting, it evolved into an online event when we weren’t allowed to meet, then changed again into a hybrid event, bringing together the best of both for people in this country and across the world. The Society has also been developing the programme to include practical workshops and forums to support radio amateurs who would like a safe and accessible environment in which to try to develop their practical skills. The RSGB General Manager has been doing the role of Convention Chair for the last three years but has now stepped back from that additional voluntary role, so the RSGB is looking for a new Convention Chair. This role needs someone who understands the advantages of both online and in-person events and who can contribute to shaping the RSGB Conventions of the future to suit the changing amateur radio audience. The RSGB is looking for someone enthusiastic, proactive, collaborative and good at working with others in a strong team. They will also need an awareness of all aspects of amateur radio, including the latest developments and what might be on the horizon. As part of the wider Convention team, they will need to suggest ideas for speakers and practical activities that will attract a range of radio amateurs. If you believe you could contribute to the development of this prestigious annual event, the RSGB would like to hear from you. Please contact the RSGB General Manager Steve Thomas, M1ACB via [email protected]

    Youngsters on the Air Month is now halfway through, with plenty more operators booked to host GB24YOTA. There is still time to work the RSGB National Radio Centre’s GB3RS station which is hosting the callsign for the duration of today, Sunday the 15th of December. On Wednesday, the 18th of December, the Simon Langton Boys School in Canterbury will be operating between 12 pm and 6 pm. On Thursday, the 19th of December, between 12 pm and 6 pm the Cambridge University Wireless Society will once again be hosting GB24YOTA. To finish up this week, Tommy, M7OMY will be operating on the 20th and 21st of December under the supervision of Las, M0BOY. Tommy is a young radio amateur and has been taking part in YOTA Month for a few years, so be sure to listen out and make a QSO with him. Search GB24YOTA on QRZ.com  to view the full operating schedule.

    The RSGB’s headquarters will close for the Christmas and New Year period from 2pm on Tuesday the 24th of December 2024. It will open again at 8.30am on Thursday the 2nd of January 2025. During that time, if you need information about amateur radio, exams or RadCom, you’ll find lots of information on the website via rsgb.org  If you are planning to visit the RSGB’s National Radio Centre at Bletchley Park over the holidays, please note that it will be closed on Christmas Eve, Christmas Day, Boxing Day and New Year’s Day. On New Year’s Eve, the NRC will close at 2 pm. The National Radio Centre will also be closed for essential maintenance works on Thursday the 2nd of January 2025. Outside of these times, volunteers look forward to welcoming visitors as usual. Remember that RSGB Members can download a free entry voucher for Bletchley Park from the RSGB website via rsgb.org/bpvoucher

    On the 6th of December, Ofcom announced an update regarding the timing of phases two and three of its amateur radio licensing framework, including changes to the new intermediate call signs and rules for Special event Stations. These phases were originally planned for December 2024 and March 2025 respectively, but Ofcom now expects to deliver them in the third quarter of 2025. For more information go to ofcom.org.uk  and search for ‘Licensing updates’.

    Now the contest news

    The UK Six Metre Group Winter Marathon started at 0000UTC on Sunday the 1st of December and ends at 2359UTC on Friday the 31st of January 2025. Using all modes on the 6m band, the exchange is signal report and locator.

    The ARRL 10m Contest started at 0000UTC on Saturday the 14th of December and ends at 2359UTC today, Sunday the 15th of December. Using CW and phone on the 10m band, the exchange is signal report and serial number. US, Canadian and Mexican stations will also send their State or Province code.

    On Thursday, the 19th of December, the RSGB 70MHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator.

    Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 12th of December 2024.

    We had another week with quiet geomagnetic conditions. Other than three hours with a Kp of four on the 9th of December, as of last Thursday when this report was being compiled it had been below three for the past seven days.

    Active region 3920 produced an impulsive M2.8 solar flare, peaking at 1006UTC on the 11th of December. A quick M2.0 flare was also detected around AR3922 in the southeast quadrant. There was also an M6.4 solar flare at 0648UTC on the 10th of December, but no Earth-directed coronal mass ejections were observed.

    The solar flux index, despite being predicted to reach 200 again, has been simmering away in the 160s and 170s. Nevertheless, the quieter geomagnetic conditions have helped HF with the extrapolated MUF over a 3,000km path often hitting 40MHz at times.

    However, the early sunset, which is around 1538UTC to 1621UTC at the moment depending on your location in the UK, means that the MUF drops off quite quickly in the afternoon. The average critical frequency at night is currently about 3.0-3.5MHz, which explains why the HF bands appear to be dead. The winter solstice is on the 21st of December, and we won’t see much change until we get to mid-January.

    There is DX to be had with CDXC members reporting working YJ0CA (Vanuatu) on 15 metres, V73WE (Marshall Islands) on 30 metres and YI1QEA (Iraq) on 10 metres.

    So, at the moment, make the most of the daytime DX and greyline openings, and reserve the evening for Top Band and perhaps 80 metres.

    Next week, NOAA predicts that the solar flux index will remain around 170 to 175. The Kp index is expected to be around two or three, apart from the 19th of December when it could reach four.

    And now the VHF and up propagation news from G3YLA and G4BAO.

    The period of enhanced Tropo activity will have faded away by this weekend as the high pressure slips away into Europe and declines. This allowed low pressure to regain control from last Friday through the current weekend.

    There may be a chance of some rain scatter propagation on the GHz bands, although it doesn’t look like a particularly good example. 

    All is not lost for Tropo followers, since the next high drifts in from the Atlantic early next week. The southern UK will benefit the most with Tropo paths to France and across Biscay. This lasts until midweek, to be followed by a return of low pressure for the second half of the week and probably a better rain scatter option than this weekend.

    The big Geminids meteor shower peaked yesterday, the 14th of December, but will linger throughout the month. The radiant source rises late afternoon and sets the following lunchtime and is most favourably positioned late evening and early morning, pre-dawn.

    Next, a consideration of aurora prospects, which are still a little enhanced by solar conditions. So, as usual, stay alert to an increasing Kp index above Kp=4 to keep in the game.

    Finally, remember that the period of Christmas and early January is well known for producing random out-of-season Sporadic-E. It's not possible to fine-tune Es prospects this far ahead, but it wouldn’t hurt to monitor the f0Es traces on the www.propquest.co.uk website between now and mid-January.

    The Moon’s declination is at maximum today, Sunday the 15th of December, and also on Monday, so expect long Moon windows with high peak elevations. Path losses are still low but rising, so it’s still a good week for EME. The 144MHz sky noise is moderate to low all week.

    And that’s all from the propagation team this week.

    RSGB GB2RS News Bulletin for 8th December 2024

    GB2RS News

    Sunday the 8th of December

    The news headlines:

    • Take part in the RSGB Construction Competition
    • A new edition of RadCom Basics has been published
    • A busy week with GB24YOTA hosted by many groups for YOTA Month

    During November, the RSGB used its Photo Friday feature on social media to highlight construction and practical skills.

    Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 5th of December 2024.

    We had another week of high solar activity but limited geomagnetic disturbances. This meant that the upper HF bands were playing ball all week.

    The Kp index only exceeded four on one occasion, on the 30th of November when it hit 4.67, but otherwise, it has been low.

    With a solar flux index mainly in the 180s, this allowed the upper HF bands to shine. The maximum usable frequency or MUF over a 3,000km path has been consistently over 35MHz during daylight hours.

    The MUF over 100km has also been more than 14MHz around midday, making 20 metres almost a local band at times thanks to near vertical incidence skywave signals! If you have worked anyone in the UK on 20 metres let us know.

    An approaching active region just off the east limb of the sun was responsible for an M2.3 solar flare on the 4th of December, so perhaps increased solar activity is on the horizon.

    Next week NOAA predicts the week will start with the solar flux index starting in the 180s, perhaps then increasing to 200 as the week progresses.

    An increased geomagnetic disturbance is forecast for the period of the 10th to the 13th of December when the Kp index could increase to four.

    If this does come to fruition, we can expect MUFs to drop until the storming has passed. As always keep an eye on Propquest.co.uk for near-real-time MUF figures and solarham.com for Kp indices.

    And now the VHF and up propagation news from G3YLA and G4BAO.

    Meteor scatter is top of the list this coming week, with the big Geminids shower lasting throughout the month and peaking on Thursday the 14th of December.

    With a peak zenith hourly rate (ZHR) of 150 it's one of the most active and reliable of the annual showers. Other lesser meteor streams are also in play, so check the meteor scatter frequencies on 144, 50 and 70MHz where digimodes MSK144 and FSK441 will dominate activity.

    We have another period of primarily unsettled weather for the lead into this weekend, with deep lows bringing heavy rain, and perhaps some snow over northern hills.

    Watch out for very strong winds with potentially damaging gales in places. By the time many of you hear this on Sunday the 8th of December, we will be mid-way through the main event but hopefully, your antennas have survived.

    The better news is that the first half of the week is dominated by high pressure, so this brings a chance to repair antennas and get some Tropo time before a slow drift back to unsettled conditions in the second half of the week.

    For other modes, GigaHertz band rain and snow scatter will be worth considering especially over the weekend and again later in the week.

    Last Friday afternoon saw another big 50MHz F2 opening to North America, so continue to be vigilant if you’re in the shack after lunch and the Kp index is below two.

    The solar conditions mean that there is still a chance of Aurora, although the Sun has been a bit quieter recently. Some days the f0Es trace on Propquest shows that weak Sporadic-E is still occurring.

    The Moon’s declination is rising again and going positive on Monday. With falling path losses as we approach perigee on Thursday, it’s a good week for EME. 144MHz sky noise is low all week.

    And that’s all from the propagation team this week.

    Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 28th of November 2024.

    Last weekend’s CQWW CW contest was a reminder of just how good HF propagation can be near sunspot maximum.

    The whole world was workable on the contest bands up to 10 metres, including the Far East, Australasia, the Caribbean and South America. It was a great opportunity to increase your DXCC total and have fun at the same time.

    This week’s solar flux index crept back above 200 again, peaking at 225 as this report was being prepared. Geomagnetic conditions have been surprisingly good over the past seven days with a peak Kp index of 3.67 on the 24th of November.

    There have been no X-class solar flares, but there has been a total of 13 M-class and 54 minor C-class flares over the past seven days. There have been coronal mass ejections, notably on the 25th of November, but they have not been Earth-directed as of the 28th.

    So, to summarise, HF conditions have been pretty good.

    We are now entering the Winter period for HF propagation, which tends to favour the low bands. So 160m, 80m and 40m come into their own and night-time DXing becomes the norm. Look for greyline openings to the west at sunrise on 80m and 160m, and also short, but good, openings on 40m in the late afternoon.

    Nighttime may bring good DX on 80m and 40m, including the Caribbean and South America.

    NOAA predicts that the SFI will remain in the low 200s next week, and while geomagnetic conditions are forecast to be good at first, the Kp index may rise to four on the 4th to 6th of December. This could result in reduced MUFs until the Kp index recovers.

    And now the VHF and up propagation news from G3YLA and G4BAO

    The unsettled theme continues through most of the next week or two. The only signs of slightly enhanced prospects for Tropo are as we close this week, and even that is restricted to some eastern areas for paths across the North Sea.

    A second option may temporarily appear around the middle of the coming week as a weak high crosses southern areas, but this one looks to be a cold high and probably not so good as a vehicle for Tropo.

    The meteor scatter prospects are aided by the last throes of the Leonids which fade away by this weekend, and the Orionids which peaked on Thursday the 28th of November, but last through the coming week.

    The unsettled weather should offer some useful GHz bands rain or snow scatter, since there will be several active weather systems around. This early in the winter is a great time for strong shower activity around the still relatively warmer seas.

    The auroral prospects are worth checking after recent activity. Look for watery-sounding signals on the LF bands as a good clue along with Kp index values greater than four.

    Last week saw some fleeting signs of Sporadic E on the Dourbes ionosonde graphs on propquest.co.uk, especially on Monday the 25th of November. This occurred typically around the middle of the day and was probably driven by the very strong jet stream and the current meteor activity.

    The Moon’s declination is negative, reaching minus 28 degrees on Monday and we are close to eclipse on Sunday. That’s followed by two days of high 144MHz sky noise, so with path losses still high, EME operators should probably take the opportunity to check their antennas after last week’s gale.

    And that’s all from the propagation team this week.

    RSGB GB2RS News Bulletin for 24th of November 2024

    GB2RS News

    Sunday the 24th of November

     

    The news headlines:

    • The past and the future – the RSGB releases more Convention presentations
    • RSGB Tonight@8 on HF antennas – join the last live event of 2024
    • Encourage youngsters on the air during YOTA Month

     

    The RSGB continues to share some great presentations from its recent annual Convention. The two this week look back to the important history of amateur radio and contrast that with how amateur radio might be influenced by modern technology. Don Beattie, G3BJ discussed the very different amateur radio environment of 1924, and the history and events of October that year when the first two-way trans-global radio communication between the UK and New Zealand took place. This centenary celebration is just one of a range of activities that have included RadCom articles and a re-enactment of the contact at Mill Hill School. In his presentation on using AI to write simple amateur radio applications, RSGB Board Chair Dr Stewart Bryant, G3YSX considers how using AI software can improve productivity and bring the ability to write effective software within the reach of more people. This presentation is being released separately as part of the RSGB’s focus on encouraging coding and programming activities amongst the amateur radio community. You can find a range of coding resources on the RSGB website at rsgb.org/coding  To watch both presentations, go to the RSGB YouTube channel and choose the ‘RSGB 2024 Convention’ playlist.

    The final RSGB Tonight@8 webinar of 2024 is on Monday the 2nd of December. The presentation by Tim Hier, G5TM will focus on the various HF antennas available for portable operating. He will also look at how to use very basic modelling software to ascertain the choices you have at your disposal. Tim’s ethos when working portable is simple, “Five minutes from arrival to operating and no more”. Tim is also the editor of RadCom Basics and will refer to content in that RSGB publication that will help radio amateurs who want to try portable operating. Watch the webinar live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat. To find out more go to the RSGB website at rsgb.org/webinars

    Now the contest news

    The CQ World Wide DX CW Contest started at 0000UTC on Saturday the 23rd of November and ends at 2359UTC today, Sunday the 24th of November. Using CW on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ Zone. The UK is in Zone 14.

    On Tuesday, the 26th of November, the RSGB SHF UK Activity Contest runs from 1930 to 2230UTC. Using all modes on the 13cm, 9cm, 6cm and 3cm bands, the exchange is signal report, serial number and locator.

    On Wednesday, the 27th of November, the UK and Ireland Contest Club 80m Contest runs from 2000 to 2100UTC. Using CW on the 80m band, the exchange is your six-character locator.

    On Thursday, the 28th of November, the RSGB 80m Autumn Series CW Contest runs from 2000 to 2130UTC. Using CW on the 80m band only, the exchange is signal report and serial number.

    Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 21st of November.

    We’ve had yet another week of relatively calm geomagnetic conditions. The solar flux index has been in the 160s and despite having 14 M-class solar flares over seven days, we haven’t had any coronal mass ejections to contend with.

    As a result, the daytime maximum usable frequency, or MUF, over a 3,000km path has been high, reaching more than 35MHz at times.

    The MUF declines after sunset, as expected, settling at about 12-13MHz, meaning the only HF band open to DX has been the 10MHz or 30-metre band.

    DX this week has included 3D2Y in Rotuma. This Pacific DXpedition has been spotted in Europe, on 20m, 15m and 17m CW, so plenty of choice as to which band you try.

    E51SGC in Rarotonga on the Cook Islands has also been spotted across many of the HF bands, but they will be leaving on the 24th of November. The good news is that the team of Stan LZ1GC and Ted LZ5QZ are moving on to Tonga as A35GC from the 25th of November until the 7th of December 2024.

    Gerben (PG5M) is active on the Falkland Islands as VP8G and has been spotted on 20m, 15m and 10m CW. He is there until the 25th of November so get in quickly!

    Next week, NOAA predicts that the SFI may rise to the mid-250s again. Geomagnetic conditions are largely predicted to be good, although do keep an eye on solarham.com for updates.

    And don’t forget the CQ Worldwide CW contest this weekend which should bring a lot of DX to the HF bands.

    And now the VHF and up propagation news from G3YLA and G4BAO.

    The weather is now in an unsettled phase with areas of low pressure bringing alternating spells of mild wet and windy weather interspersed with colder brighter and breezy showery weather. 

    This raises a couple of radio-related points; one is that we will see some very strong and potentially damaging winds in some areas, so check daily forecasts and make sure your mast guys are secure; and secondly an absence of any marked high-pressure Tropo weather. 

    Rain and snow scatter may be worth checking on the GHz bands in such unsettled weather. Meanwhile, meteor scatter is worthy of greater attention as next week’s list of showers includes the small Alpha Monocerotids shower and the tail end of the big Leonids shower.  

    This introduces another potential nugget of interest in that it is widely accepted that meteors form the source material for Sporadic-E. Despite being out of season in the traditional sense, the prevalence of stronger jet streams in unsettled weather makes the next week a possible ‘watch period’ for Es.

    If you are curious about what these might look like, check out the propquest.co.uk  website and look for the near vertical incidence skywave or NVIS tab for Wednesday the 20th of November 2024.

    During the two events in the middle of the day and evening, the critical frequency of the Es layer reached values of nearly 10MHz, which could equate to four-metre propagation on a good day. You will see the Es blog tab upper air charts also show a jet stream of greater than 100 knots. 

    For EME operators, the Moon has passed peak declination so Moon availability and peak elevation will be falling. Path losses are high and rising towards apogee on Tuesday the 26th. 144MHz sky noise is low all week.

    And that’s all from the propagation team this week.

    RSGB GB2RS News Bulletin for 17th November 2024

    GB2RS News

    Sunday the 17th of November

    The news headlines:

    • The RSGB has launched a new practical events section on its website
    • The RSGB Awards Manager has added categories to the IARU Region 1 Award
    • There is still time to host the Youngsters on the Air Month call sign

    The RSGB is keen to promote practical events for radio amateurs as a way of developing their skills and retaining their interest in amateur radio. The Society has also demonstrated that buildathons are a great way of engaging new audiences, giving people a taste of amateur radio in a fun and supportive environment. As part of its strategy, the RSGB held two workshops at the 2024 Convention to introduce individuals to radio-related usage of Micro Controller Units, or MCUs as they are often known. The Society also holds annual build-a-radio events at Bletchley Park for youngsters, with the kits provided by the Radio Communications Foundation. To support radio amateurs to try practical skills themselves or to put on their events, the RSGB has published a new section on its website that is dedicated to practical events. You’ll find a guide to running a buildathon, detailed information from the MCU workshop as well as a short video to inspire you! Feedback from the RSGB’s events has been wholly positive with requests for similar activities around the country. Could your club host an event and perhaps even boost its numbers at the same time? Find out more at rsgb.org/practical-events

    The RSGB Awards Manager has announced that, with the support of the Board, he has added new categories of achievement to the IARU Region 1 Award. These include WARC bands only, 10MHz only, 18MHz only and 24MHz only. The standard IARU Region 1 Award check spreadsheet should continue to be used for these categories. However, award chasers are advised to keep separate versions for each band or set of bands. There are no mode or power restrictions and there is no distinction between fixed and portable stations; you just have to be operating within the same country for all QSOs used in the application. There aren’t any limitations on the start dates for the awards other than the dates for particular countries as identified in the check sheet. This reflects, for example, when a country became a member of the IARU. The RSGB would like to thank the award chasers who contributed to the discussions about adding new categories.

    With just two weeks to go until Youngsters on the Air Month, operating slots for GB24YOTA are fast filling up. The special call sign will be active throughout December and is a fantastic opportunity to get youngsters active on the amateur bands. Whether you are part of a school, university, youth group, club or individual, the RSGB would love you to be involved. The Society would be delighted to see the callsign hosted every day during December and see as many youngsters on the air as possible. Be part of this goal by visiting QRZ.com and searching GB24YOTA to check availability. Operating slots aren’t fixed and can be adjusted to suit your timings, so don’t delay. Email Jamie, M0SDV via [email protected] now. Visit rsgb.org/yota-month to find out more.

    The RSGB National Radio Centre at Bletchley Park will be closed on Christmas Eve, Christmas Day, Boxing Day and New Year’s Day. There will also be reduced hours on New Year’s Eve when the centre will be closing at 2 pm. Following the seasonal closures, the NRC will also be closed for essential maintenance works on the 2nd of January 2025. Outside of these times, volunteers look forward to welcoming visitors as usual. Remember that RSGB Members can download a free entry voucher for Bletchley Park from the RSGB website via rsgb.org/bpvoucher.

    Visitors to and from CEPT countries such as the UK can now operate more easily in the Cayman Islands, which has now joined the CEPT T/R 61-01 Reciprocal agreement. This change was agreed at the CEPT meeting last month.

    Now the contest news

    Tomorrow, Monday the 18th of November, the RSGB FT4 Contest runs from 2000 to 2130UTC. Using FT4 on the 80m to 10m bands, where contests are permitted, the exchange is a signal report.

    On Tuesday, the 19th of November, the RSGB 1.3GHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 23cm band, the exchange is signal report, serial number and locator.

    On Thursday, the 21st of November, the RSGB 70MHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator.

    The CQ World Wide DX CW Contest starts at 0000UTC on Saturday the 23rd of November and ends at 2359UTC on Sunday the 24th of November. Using CW on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ Zone. The UK is in Zone 14.

    Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of November.

    The solar flux index took a downturn this week, ending up at 150. The visible solar disk is looking rather bare compared with a couple of weeks ago.

    This is the lowest SFI value since the 2nd of May 2024, but it is only a matter of time before we see another sunspot appear as we make our way through solar maximum.

    The good news is that we have been pretty devoid of solar flares and coronal mass ejections, with only a few M-class flares occurring. Any CMEs were not Earth-directed and so the Kp index stayed low.

    As a result, the bands are still playing ball. A quick look on 10 metres at 10.00UTC on Thursday the 14th showed the 4X6TU (Israel), OH2B (Finland) and LU4AA (Argentina) International Beacon Project beacons were romping in on 28.200MHz.

    Going down to 15 metres it was even better, with ZL6B (New Zealand), VK6RBP (Australia) and JA2IGY (Japan) all audible on 21.150MHz.

    Also, the proton flux from the Sun remains low, which bodes well for polar paths.

    Next week the Space Weather Prediction Centre forecasts that the solar flux index will rise again, no doubt as new or returning sunspots appear, perhaps putting us into the low 200s.

    From a geomagnetic perspective, unsettled conditions are forecast for Wednesday, the 20th of November when the Kp index could rise to four.

    Looking further ahead, fingers crossed for the 23rd and 24th weekend when the CQ Worldwide CW contest takes place!

    And now the VHF and up propagation news from G3YLA and G4BAO.

    It was more of the same on 50MHz last week, with what may be a mix of Es and F2-layer propagation producing morning openings in the afternoon to the Gulf States, Southeast Asia, and the Americas.

    On the higher bands, with the high pressure just hanging on in its colder guise, next week looks distinctly on the wintry side for some areas.

    The high pressure has, along with its predecessor, given us at least two weeks of Tropo conditions on the VHF bands. The expected change-over to low pressure takes place on Sunday and drives a colder northerly weather pattern down across the UK, even to southern areas. This means that the majority of next week is a good time to look for rain scatter.

    Regarding meteor scatter, the peak of the Leonids occurs today, the 17th of November, with rates of 15-20 per hour.

    Also, occasional peaks of the Kp index above four should tempt us to beam north for chance aurora openings. As usual, check the VHF beacons and clusters for signs of activity during the afternoon and evenings when the auroral oval is displaced southwards nearer to our part of the world.

    It's a good week for EME operators, the Moon reaches peak declination on Monday morning, but path losses are rising as we have passed perigee on Thursday the 14th. 144MHz sky noise is moderate, reaching 500 Kelvin on Sunday night.

    And that’s all from the propagation team this week.

    Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of November.

    We had another week of high solar flux and good conditions on HF.

    Solar activity remained at high levels thanks to an impulsive X2.3 solar flare around active region 3883 at 13:40 UTC on the 6th of November, but the event was not responsible for a coronal mass ejection (CME).

    The Kp index remained below 4.5 all week, with a solar flux index in the range of 240-260. That was more than enough to keep the ionosphere very active.

    A recent report on spaceweather.com  suggested that the solar cycle may have peaked in the Sun’s southern hemisphere but may still have a way to go in its northern hemisphere.

    It's usual for there to be two peaks in a solar cycle as the two hemispheres are seldom synchronised. We will have to wait and see, but it could mean another three to six months of high SFI numbers as the northern hemisphere catches up.

    A solar filament located in the southwest quadrant erupted on the 7th of November. A coronal mass ejection, or CME as it is also known, occurred but appeared to be off the Sun-Earth line, so no major impacts are expected.

    A sunspot group turning into view from off the southeastern limb has been assigned active region 3889 and is producing M-class solar flares. The probability of further M-class flares stands at 80%. Meanwhile, the risk of an X-class flare currently stands at 35%.

    A coronal hole is currently Earth-facing and could cause some disruption sometime around Saturday 9th.

    The solar proton flux has decreased to normal levels, so polar paths should now be unaffected.

    Next week, NOAA predicts that the SFI could decline into the range of 165-185. Geomagnetic disturbances are forecast for the 11th and 12th, and again on the 15th, with the Kp index predicted to reach four.

    Meanwhile, we do urge you to get on 10 metres, which is currently experiencing some fine DX openings. This month and next will probably give the best chance of good 10-metre propagation for a while.

     And now the VHF and up propagation news from G3YLA and G4BAO

    Another week has just passed with daily F2-layer propagation on 50MHz providing morning openings to Southeast Asia, and the Americas in the afternoon. Expect more in the coming week. 

    The current spell of high pressure has had a good run with some excellent Tropo conditions, with the best DX along the side of the high pressure.

    This weekend will see the high finally giving way as weak Atlantic fronts move in from the west. This will soon be replaced by a new high building in the colder air behind the weekend fronts. It may look like Tropo should come back, but this high may be less productive.

    The major change of weather pattern comes before mid-week, when it may turn more unsettled as low pressure moves closer to eastern areas from the North Sea. This general move towards more unsettled conditions will continue through the end of the week.

    In terms of propagation, good Tropo will be replaced by some patchy rain scatter opportunities for the GHz bands from about the middle of next week.

    Staying with scatter modes, meteor scatter looks promising with the Taurids peaking on Tuesday the 12th and the Leonids due to peak on the following weekend on Sunday the 17th.

    The solar conditions continue to offer chance occurrences of aurora due to solar flares or CMEs so, as usual, keep a watch on the Kp index going above Kp=4.

    An occasional reminder of the possibility of out-of-season Es for the digital modes is timely. Recently the critical frequency of the Es layer has reached 7MHz on the Dourbes ionosonde plotted on www.propquest.co.uk  and in theory, this would be good enough for a 6m band path.

    For EME operators, Moon declination is negative but rising, going positive again on Tuesday the 12th. Path losses are falling as we approach perigee next Thursday the 14th. 144MHz sky noise is moderate to low this coming week.

    And that’s all from the propagation team this week.

    Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday 31 October 2024.

    Last weekend’s CQWW SSB contest showed just how good autumnal HF conditions can be. Many contestants worked more than 100 countries or DX entities on each and every HF band.

    With a solar flux index of 238 on Saturday and 246 on Sunday, plus low Kp indices all weekend, it was about as good as it could get. There were two three-hour periods where the Kp index hit four and 4.33, but it was otherwise in the ones and twos.

    An X-class solar flare occurred on Saturday the 26th at around 07:15 hrs UTC, but this had little effect and the MUF over a 3,000km path was back above 28MHz quite quickly.

    The rest of the week saw numerous M-class and C-class solar flares occur and a Kp index that did get up to four at times, but once again the MUF remained above 28MHz during daylight for most of the time.

    Interestingly, there have been times when the critical frequency over the UK has hit 14MHz, making 20m almost a local chat band via Near Vertical Incidence Sky Wave or NVIS communications! These openings may be short-lived so make the most of them should they occur.

    Nighttime critical frequencies have generally been around 4.5-6MHz, meaning a MUF over a 3,000km path over 14MHz in the first half of the night and around 10-12MHz in the second half.

    The solar proton flux has been above the 10MeV warning threshold but is now falling as of Thursday 31st. This may improve signals that pass through the polar regions, such as the UK to the far west of Canada and Alaska, and the UK to Japan.

    Next week NOAA predicts that the SFI will start at around 240, but perhaps fall to around 195-200 as the week progresses. ESA predicts that the solar wind speed could increase around November 4th and could cause disruption.

    As always, we are at the mercy of solar flares and CMEs, which could disrupt HF propagation, so we recommend keeping an eye on solarham.com for daily updates.

     And now the VHF and up propagation news from G3YLA and G4BAO

    The Autumn Equinox period continued to bring F2-layer propagation to 50MHz with almost daily morning openings to VK and JA and afternoon openings to the Americas for some.

    Stations in the far South and West of the island were favoured. Side scatter in the Indian Ocean brought the JAs on a 90-degree beam heading, an effect noted at previous sunspot maxima.

    The autumn is typically a time for quiet settled weather, a season of mist, and this is where we are going for the period through to the end of next week. It's worth a couple of reminders of how it all works since, although it's likely to be pretty much the same ‘big picture’ of dominant high pressure, there will be subtle differences.

    Firstly, there are two types of high pressure; one that builds in warm air and the other in cold air. The warm air version is the current offering, and this means quite cloudy conditions at times with moist air below the temperature inversion and very dry air above the inversion.

    Second, the quality of the ducting is determined by the change of the refractive index across the inversion and a large part of the refractive index change comes from a contrast of moisture, so signs of cloud and/or fog moisture are good omens for a lift. We may swap over to a cold air high later next week, which could lessen the Tropo quality.

    Meteor scatter prospects are on hold pending the Leonids meteor shower, which peaks mid-November. A dominant high pressure means that rain scatter is not likely to be a big player for the GHz bands next week.

    There is a possible heads-up for aurora since the solar conditions still offer chances for the Kp index to rise – anything over Kp=4 is worth a longer look – and don’t forget that ‘watery’ signals on the lower HF bands such as 40m and 80m are also a good sign.

    For EME operators, Moon declination reaches a minimum (that is, maximum negative declination) next Tuesday when the Moon only reaches nine degrees peak elevation and is only above the horizon for six hours between 1200 and 1800hrs. Path losses, on the other hand, are falling all week.

    144MHz sky noise is moderate to high, peaking at more than 3,000 Kelvin on Tuesday the 5th before dropping back to moderate levels.

    And that’s all from the propagation team this week.

    RSGB GB2RS News Bulletin for 27th October 2024

    GB2RS News

    Sunday the 27th of October

    The news headlines:

    • The RSGB releases a snapshot video of the exciting Girlguiding ISS contact
    • You can listen to the Chair of the RSGB’s Propagation Studies Committee on the latest episode of the ICQ podcast
    • The RSGB has begun releasing presentations from its 2024 Convention

    On the 5th of October, in her first official engagement as Girlguiding Patron, Her Royal Highness The Duchess of Edinburgh joined 100 excited Brownies, Guides and Rangers in making a live amateur radio contact with the International Space Station. The event was organised by The Radio Society of Great Britain and Amateur Radio on the International Space Station, or ARISS as it is usually known, in collaboration with the UK Space Agency, Girlguiding Surrey West and Brooklands Museum’s Innovation Academy programme. The aim was to promote the engagement and involvement of girls and young women in science, technology, engineering and mathematics. Everyone had a fantastic day and after the contact, the girls enjoyed a variety of STEM activities including making Snail Morse keys, playing Morse battleships, learning about the CubeSat Simulator and making stomp rockets. The RSGB has created a short video snapshot of the day which you can see on its YouTube channel at youtube.com/theRSGB – take a look!

    The latest episode of the ICQ Podcast is available to listen to online and features RSGB Propagation Studies Committee Chair, Steve Nichols, G0KYA. During episode 441 Martin Butler, M1MRB talks to Steve about propagation and how the sunspot cycle has taken off to impact conditions positively. They also discuss Ham Radio Science Citizen Investigation, which is also known as HamSCI, a collective that enables university researchers to collaborate with radio amateurs in scientific investigations. To access the interview, select episode 441 at icqpodcast.com and listen from 1 hour and 35 minutes.

    The RSGB 2024 Convention weekend brought together hundreds in person and thousands via the livestreams. As well as the ‘Convention in a nutshell’ video released last week, the Society has now published two of the main presentations. The first is the keynote speech about the future of amateur radio licensing and education by Rafal Lukawiecki, EI6LA. The second looks at inspiring the next generation by the RSGB’s two new Youth Champions Chris Aitken, MM0WIC and Rhys Williams, M0WGY. You will find both presentations, as well as the full two days of live stream content, in the RSGB 2024 Convention playlist on the Society’s YouTube channel. Remember to subscribe to the channel so you don’t miss additional presentations when they’re published. There is also still time to share your feedback about the in-person event or the live stream, but the feedback forms will close at the end of this month. Head over to rsgb.org/feedback if you attended the event, or rsgb.org/livestream-feedback if you watched via the livestream. Let the team know what you enjoyed!

    If you are thinking of taking an amateur radio exam before Christmas, there are two important dates you need to be aware of. The last date you can take an exam at a club, whether online or on paper, is Friday the 13th of December. If you want to take an exam online at home, the last date you can do that is Friday the 20th of December. The RSGB Exams Team will, where possible, post-out exam results before HQ shuts over Christmas and New Year. Exams will resume on Monday the 6th of January 2025 and the booking system will be available over the festive season so you can book exams for January onwards. You can book online on the RSGB website at rsgb.org/exampay

    On Friday the 18th of October the RSGB, Mill Hill School and a team of radio amateurs in New Zealand took part in a special celebration to mark the centenary of the first successful two-way trans-global communication between radio amateurs in the UK and New Zealand. The original contact between Frank Bell, 4AA in New Zealand and Cecil Goyder, 2SZ in Mill Hill School in North London was re-enacted at the school on a wavelength as close as possible to the original. Members of Goyder’s family watched the re-enactment and chatted to pupils. As part of wider celebrations for the day, the school put on activities including a build-a-radio workshop. Students at the school showed significant interest in amateur radio, with several students signing up to be part of a new radio club that will be set up by the school’s physics teacher. The overall event was led by RSGB Life Vice-President Don Beattie, G3BJ who said that he was delighted by the success of the event and that it had allowed pupils to learn how ground-breaking that first radio contact was with New Zealand. Call sign G2SZ was operational for four days surrounding the centenary, during which operators achieved approximately 1,250 contacts. To find out more about this unique celebration go to www.gb2nz.com and search for ‘GB2NZ re-enactment’ on the RSGB website.

    The Memorial Day QSO Party is an activity providing participants with an opportunity to honour amateur radio operators who are now Silent Key. The event is being sponsored and managed by the First Class CW Operators’ Club and is open to all licensed amateurs. The event begins at 0900UTC on the 1st of November 2024 and ends at 0859UTC on the 2nd of November. More information is available at g4foc.org or by emailing [email protected] or [email protected]

    Ofcom has notified stakeholders that the next release of its licensing service will be delayed due to issues that have arisen during software development. According to the Ofcom website, the delays have impacted Phases 2 and 3 of the planned changes to the amateur radio licensing framework. Phase 2 includes changes to new Intermediate callsigns, special event station rules and restrictions on the number of callsigns an individual may hold. Revised plans are expected to be published soon. You can read the update on the Ofcom website via tinyurl.com/OFCOMOCT24

     Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 24th of October 2024

    Last week’s solar conditions couldn’t have been much better. We had a week of high solar flux indices, relatively calm geomagnetic conditions and, other than an X-class solar flare, not much else to report.

    The solar flare originated from active region 3869 and reached a strong X3.3 in the early hours of October 24th. This event was associated with a coronal mass ejection, or CME, based on solar dimming following the event, but because the flare location was located off the east limb, it was directed mostly away from Earth.

    Once again, all the sunspots are in the southern hemisphere, but activity appears to be growing. This could spell trouble over the next week.

    This weekend, the 26th and 27th, the CQ Worldwide SSB contest is taking place and conditions should be excellent, with a combination of high solar flux and autumnal HF conditions.

    Maximum usable frequencies, or MUFs, are generally higher than 28MHz from dawn until dusk. Nighttime MUFs over 3,000km are still just above 14MHz, although you might get better results by dropping down to 10MHz if the 20m band doesn’t work for you.

    Next week, NOAA predicts that the solar flux index may rise again, perhaps hitting 185 as we enter November. However, this current bunch of sunspots, which are rotating to be Earth-directed next week, appear more active and we could see more solar flares and CMEs, which could throw a spanner in the works.

    A solar flare could impact the ionosphere by increasing D-layer absorption, for up to an hour or so, and possibly launch a coronal mass ejection.

    If a CME hits the Earth, expect the MUF to plummet, at least for a day or two until the ionosphere recovers.

    And now the VHF and up propagation news from G3YLA and G4BAO

    The Autumn Equinox period brought some amazing ionospheric propagation to 50MHz on Thursday last week with stations in the UK working morning paths to VK, JA, DS and XV among others.

    Typically for 50MHz DX, the skip zones were sharp and moved rapidly. Stations even a few kilometres apart experienced very different signals and paths. Those with a low noise floor had a huge advantage as signals were generally weak in the UK and only good for FT8. However, some reports of a VK station at +5 bucked this trend.

    Next week will offer some reasonable Tropo conditions, although not without some occasional interruptions from weak frontal systems, especially in the far southwest and the far northwest of Britain. It’s not clear if these represent good rain scatter options, but they are more likely to temporarily curtail any Tropo for a while.

    The solar conditions continue to feed the occasional aurora alert our way, so it’s always good to monitor the Kp index for signs of it increasing above 4. It won’t always go on to produce a radio aurora, but it's worth keeping an eye on things.

    The meteor scatter prospects continue to be elevated by the decline of the Orionids, which peaked on Tuesday the 22nd, and the Taurids, which are a very low-rate shower, but technically cover a broad period into December. The Leonids are the next major shower, but that doesn’t peak until mid-November.

    Lastly, looking at the out-of-season Sporadic-E prospects, there are always days with minor enhancements of the critical frequency of the Sporadic-E layer, as shown on the propquest.co.uk graphs. Certainly, there are stronger jet streams available in the autumn and winter, but other elements of Sporadic-E are not so favourable. It’s usually a very marginal outcome at best, but good enough for the 10 or 6m bands and mostly for digital modes such as FT8. 

    It could well be that trans-equatorial propagation, or TEP, is a more fruitful venture.

    For EME operators, Moon declination is positive, but falling, going negative on Tuesday the 29th. Path losses are rising, reaching a maximum at apogee on the morning of Wednesday the 30th. 144MHz sky noise is low until Friday the 1st of November when the Sun and Moon are close in the sky.

    And that’s all from the propagation team this week.

    RSGB GB2RS News Bulletin for 20th October 2024

    GB2RS News

    Sunday the 20th of October

    The news headlines:

    • The RSGB welcomes your feedback on its 2024 Convention
    • Today is the last chance to get involved with JOTA 2024
    • The RSGB is looking for Youth Champions

    The RSGB’s 2024 Convention took place last weekend and brought together hundreds in person, as well as many more from across the globe who watched via the livestream. The Society is already receiving an overwhelming amount of positive feedback, but if you did attend the Convention and haven’t yet completed the feedback form, please go to rsgb.org/feedback and share your thoughts. If you watched the livestream the Society would also love to hear your feedback. Please visit rsgb.org/livestream-feedback and let the team know what you think of the online event. The feedback forms will be closed at the end of October. The live streams for both days will remain available for everyone to watch, so if you’d like to catch up on the selection of presentations that were aired, go to the RSGB website and search for ‘Convention 2024 Livestream’. As well as talks from the weekend, you’ll find exclusive special interviews and pre-recorded videos.

    Today, the 20th, is the last day of Jamboree on the Air, also known as JOTA. The event promotes friendship and global citizenship and is a brilliant celebration of amateur radio among the Scout Association. The Society has compiled a list of Scouting groups that are involved with the annual event and has shared it on its website. The list is available by going to rsgb.org/jota and choosing the ‘JOTA Stations on the Air’ link on the right hand side of the page. The RSGB would love to see your photos of Scouts getting involved with JOTA, so tag @theRSGB and also use #JOTAJOTI to be involved in the conversation on social media. If you’re not involved with a JOTA station do listen out and encourage the young operators on the air. There will be a report in RadCom so please send details and photos from your event to [email protected] by the 15th of November.

    Following the recent appointment of two Youth Champions for schools and universities, the RSGB is keen to expand the team. The Society is looking for a Youth Champion for scouts, guides and cadets, and another to lead activities and create resources to support young people once they have gained their Foundation licence, motivating them to try new things within amateur radio. The four Youth Champions will work closely as a team, as well as with the RSGB Board Liaison, Ben Lloyd, GW4BML and the RSGB Outreach Team. Together, the Youth Champions will also create a youth team and run a net or sked to involve all youngsters. Do you have what it takes to engage with young people and support them on their amateur radio journey? Another part of each Youth Champion’s role is to give input and support for current activities, such as promoting and participating in Youngsters on the Air Month each December. If you are proactive, experienced at managing your own time efficiently, a good leader who can build relationships and mentor young people, and you are passionate about growing the number of young people involved in amateur radio, then one of these roles could be for you! Take a look at the youth activities on the RSGB website at rsgb.org/youth and see some of the great things that are happening already. If you’re interested in being part of the team, contact Youth Board Liaison Ben Lloyd, GW4BML via [email protected]

    Now the Special Event news

    Special event station PF16F is active to say farewell to the F-16 fighter aircraft, or Fighting Falcon. After 45 years of service, from 1979 to 2024, the F-16 will retire from the Royal Netherlands Air Force. Members of Radio Club Limburg will be operating the callsign until the 30th of November 2024 and hope to work as many amateur radio operators across the world as possible. For more information about the station visit rclb.nl/pf16f

    As part of the celebrations to mark the centenary of the world’s first trans-global two-way radio communication, special callsign GB2ZL has been active at times from the UK. This is in addition to the main UK activity from GB2NZ, G2SZ and others. On Tuesday the 15th of October, the GB2ZL station, operated by Chris GM3WOJ from near Inverness, made a remarkable QSO with the ZL4AA team located just North of Dunedin. The ZL4AA station was operated by Dave ZL4DK, Mike ZL4OL and Stephen ZL4BN. This QSO, on the 40m band, long path at 0721UTC, was made using CW. 559 reports were exchanged each way and the operators at both ends were thrilled to make the contact. At each end of the QSO was an 80-year-old all-valve military transceiver from New Zealand, the iconic ZC1. These radios date from 1944, just 20 years after the first UK to New Zealand QSO. For more information about the station and the ZC1 transceiver visit the GB2ZL page at QRZ.com

    Sylvia, OE5YYN is active as OE20SOTA until the 31st of October to mark the 20th anniversary of Austria joining the Summits on the Air programme. Details of a certificate that is available for working the station are available at QRZ.com

    Now the DX news

    Harold, DF2WO is active as 9X2AW from Rwanda until the 22nd of October. He is operating using CW, FT4 and SSB on the 80 to 10m bands. You might also catch Harold operating via the QO-100 satellite. When possible, he also hopes to be QRV on the 6m band. QSL via OQRS.

    Stephane, F5UOW is active as FR/F5UOW from Reunion Island, AF-016, until the 28th of October. He is operating using CW only on the 17 to 10m bands. QSL via Logbook of the World only.

    Now the contest news

    The Worked All Germany Contest started at 1500UTC on Saturday the 19th and ends at 1500UTC today, the 20th of October. Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number.

    On Tuesday the 22nd, the RSGB SHF UK Activity Contest runs from 1830 to 2130 UTC. Using all modes on 2.3 to 10GHz frequencies, the exchange is signal report, serial number and locator.

    On Thursday the 24th, the RSGB Autumn Series SSB Contest runs from 1900 to 2030 UTC. Using SSB on the 80m band, the exchange is signal report and serial number.

    The CQ World Wide DX SSB Contest starts at 0000 UTC on Saturday the 26th and ends at 2359 UTC on Sunday the 27th of October. Using SSB on the 160 to 10m bands, the exchange is signal report and CQ Zone. The UK is in Zone 14. 

    Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 17th of October 2024

    The past week has been characterised by a low geomagnetic Kp index and excellent conditions on HF, including the 10m band. With a solar flux index between 168 and 195, and a Kp index that never rose above 4, conditions have been better than the previous week, which suffered from the bad effects of solar flares and coronal mass ejections.

    This came as NASA, NOAA and the International Solar Cycle Prediction Panel announced that the Sun has reached its solar maximum period, which should continue for the next year.

    The announcement was not unexpected, and the exact period of maximum activity won’t be known for some time. But it was a wake-up call for radio amateurs to get on the bands and make the most of the conditions!

    NOAA anticipates additional solar and geomagnetic storms during the current solar maximum period and during the declining phase of the solar cycle.

    The solar flux index fell from its 200-plus highs to be in the 160 to 195 range last week. But this was still more than enough to keep the ionosphere running. Maximum usable frequencies over a 3,000km path have been consistently over 28MHz during daylight, falling to around 11MHz overnight.

    Next week, the Space Weather Prediction Centre thinks the solar flux index will rise into the 200s again, but we may also get some geomagnetic disturbances, namely on the 22nd and 23rd when the Kp index might rise to around 4.

    Meanwhile, October can be one of the best months for HF propagation with good 10m band openings to Australasia in the morning and North and South America in the afternoon.

    And now the VHF and up propagation news from G3YLA and G4BAO

    The current unsettled spell of weather seems likely to continue into next week and is not atypical at this time of year. We should expect a more changeable pattern around the autumn as the main polar front jet stream migrates south across the UK into its winter state over the Mediterranean.

    That said, there may well be some brief interludes when the extended region of high pressure across Europe influences conditions over the British Isles, more specifically the southeastern corner.

    This is shown by some models around midweek for potential Tropo from southeastern England into the continent or across the North Sea to northern Europe and southern Scandinavia.

    The obvious mode to result from this unsettled weather will be rain scatter and it is probable that the GHz bands will enjoy this period of weather.

    Meteor scatter in October has a few showers to maintain interest. The Orionids and the Taurids are both active during the coming week. In fact, the Orionids, associated with the comet Halley, peak on Monday and Tuesday.

    Just a final note about Sporadic-E, which is ‘out of season’. Remember that there are no ‘zero Sporadic-E months’ and recent indications have tended to show the response of raised critical frequencies of the Sporadic-E layer occurring around the middle of the day on the propquest.co.uk NVIS graphs.

    You may also see peaks earlier in the day around dawn, which is the peak time for meteor input. Beware, it is easy to get hooked on out-of-season Sporadic-E hunting!

    For EME operators, Moon declination is positive and rising. Path losses are rising again after the perigee on Thursday the 17th. So, we have increasing peak Moon elevations and longer Moon windows until Tuesday the 22nd. 144MHz sky noise is low to moderate for the rest of the week.

    And that’s all from the propagation team this week.

    RSGB GB2RS News Bulletin for 13th October 2024

    GB2RS News

    Sunday the 13th of October

    The news headlines:

    • The RSGB 2024 Convention is taking place this weekend
    • Two new volunteer Youth Champions have been appointed by the RSGB
    • Celebrations are underway to mark the first trans-global two-way radio communication

    The RSGB Convention has been in full swing this weekend. If you haven’t been able to attend, the RSGB has provided a packed live stream on each day and those live streams are available for anyone to view. Full of presentations, interviews and videos to inspire you, this is another way to enjoy your Convention, in your way. Either go directly to the RSGB YouTube channel or head over to rsgb.org/livestream to see the programme of presentations and the links to the livestreams.

    The RSGB is delighted to announce the appointment of two new volunteer Youth Champion roles. Chris Aitken, MM0WIC will be the RSGB’s School Youth Champion and Rhys Williams, M0WGY/AJ6XD will be the University Youth Champion. Chris is a Computing Science teacher at Wick High School, Caithness. Since 2023, Chris has been running the Wick High School Radio Club, GM0WHS, providing students with a wide range of experiences in amateur radio. He has four students who have passed their Foundation licence exam and are now taking on leadership roles within the club and assisting the latest cohort in their studies. He is also a member of the RSGB Outreach Team. You can contact Chris via [email protected]  Rhys represented the RSGB at the Youngsters on the Air Camp in Prague this year. He sent back daily reports on his activities which you can still see on the website under the summer camps tab at rsgb.org/yota  He is starting a PhD in Aerospace Engineering at the University of Oxford and is keen to help the RSGB support the growth of amateur radio in universities across the UK. You can contact Rhys via [email protected]  Ben Lloyd, GW4BML is the Board Liaison for youth activities. He said that he welcomes Chris and Rhys to their new youth volunteer roles and looks forward to working closely with them in the future to attract and grow RSGB youth membership. He explained that the three of them have already had some positive conversations and shared some good ideas, which they will be putting into place over the coming months.

    This week marks the centenary of the world’s very first trans-global two-way radio communication. On the 18th of October 1924 Frank Bell, 4AA, from New Zealand, and Cecil Goyder, 2SZ, from North London, changed how we communicate forever by making contact on amateur bands. To commemorate this historic contact, special callsigns will be active, and awards and QSL cards will be available for those who make contact with these special stations. GB2NZ and ZM100DX have already been active since the start of the month. Starting tomorrow, until the 20th of October, calls reflecting Goyder’s callsign, G2SZ, and Bell’s, ZL4AA, will be active. This will include activity here in the UK from Mill Hill School in North London which is the original location from which Goyder made his contact. On Friday the 18th of October, radio amateurs will also be recreating and re-enacting the first contact between Goyder and Bell. It is hoped that the QSO will be made on a wavelength close to that used in 1924. To find out more about this unique celebration go to gb2nz.com

    YOTA Month is just around the corner, and the RSGB is looking for volunteers to host the GB24YOTA callsign throughout the month of December. As in previous years, schools, clubs, guide and scout groups and also individuals are invited to host young radio amateurs whilst they operate with the callsign. Each day during the month has been split into a number of operating slots that you can book. In recent years, this system has allowed many more youngsters to get on the radio throughout the month. You can see the operating calendar by visiting QRZ.com and searching for GB24YOTA. Operators should be below the age of 26. Those who do not hold a Full amateur radio licence should be supervised by an appropriate Full licensee whilst operating. The RSGB is pleased that previous activators have already reached out to book their operating slots but there are still many more up for grabs! To book an operating slot or for more information about YOTA Month, please email Jamie, M0SDV at [email protected]

    During last month’s Hamfest in Newark, the ICQ Podcast team spoke with RSGB President John McCullagh GI4BWM, RSGB Board Chair Stewart Bryant G3YSX and RSGB General Manager Steve Thomas M1ACB. Listen to Episode 440 of the podcast series to hear them discuss some of the many events that the Society is currently involved with.

     Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 9th of October 2024

    What a difference a week makes when it comes to HF propagation!

    This last week has been characterised by solar flares, coronal mass ejections, or CMEs for short, and an elevated Kp index. Put together, this has resulted in dire conditions on HF, reminiscent of a solar minimum.

    A visible aurora was seen from the UK once again after the Kp index hit 7.33 on the 8th of October.

    Numerous CMEs have hit the Earth and the solar proton flux has risen, resulting in a moderate S2 radiation storm as particles blasted away from the flare site.

    This means poor trans-polar paths until the solar wind abates and the storm settles.

    Maximum usable frequencies have been badly affected and struggled to get much past 14MHz over a 3,000km path on the 8th of October. Geomagnetic storms were also forecast for Thursday the 10th and Friday the 11th.

    That’s a shame as, before the CMEs hit, HF had been humming with a lot of DX on the 28MHz band and many five-watt beacons romping in from the USA.

    Next week, NOAA predicts that the solar flux index may drop back into the 170s, but it’s anyone’s guess as to how geomagnetic conditions will pan out.

    We have had three X-class solar flares over the past week and on Wednesday the 9th the probability of another X-class solar flare was estimated at 30% and an M-class event at 75%. So, it may be a case of ‘batten down the hatches’ on HF until the storm conditions pass.

    This is not uncommon at this point in the solar cycle and unsettled conditions are likely to continue as we move along the downward portion towards the solar minimum.

     And now the VHF and up propagation news from G3YLA and G4BAO

    The current spell of unsettled weather is probably going to flip into high-pressure mode a couple of times during the coming week. The first of these will be today, the 13th, and through the first half of next week.

    However, by Wednesday the next change back to low pressure should be with us, closely followed by another attempt to build high pressure later in the week. 

    This offers something for everyone with prospects for rain scatter on the GHz bands and the possibility of Tropo.

    The prospects for meteor scatter are also good with October offering several useful meteor showers.

    While 50 and 70MHz are the best for the mode, look at 144.360MHz in MSK144 digimode. Or, if it’s a shower peak, 144.200MHz, the SSB meteor scatter calling channel, to see what’s around.

    The solar conditions continue to behave like a solar maximum and, with several recent powerful flares and CMEs to stir things up, we should continue to check the bands for signs of aurora. 

    The recent RSGB CW 80m Autumn Series Contest on Monday the 7th of October was about as auroral as it gets with a strong flutter on signals and a challenging hour and a half for participants – so not just an effect for VHF. 

    The RSGB 1.3GHz UK Activity Contest coming up next week on Tuesday the 15th may be on the changeover from high pressure to low. Tropo might be limited to eastern areas for paths across the North Sea to northern Europe.

    For EME operators, Moon declination is still negative but will rise to positive by Tuesday night. Path losses are falling towards a minimum at perigee on Thursday the 17th.

    So, we have increasing peak Moon elevations and longer Moon windows with the lowest loss for the coming week. 144MHz sky noise is low for the rest of the week.

    And that’s all from the propagation team this week.
