    Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:

    Broadcaster: Israel Broadcasting Authority, Jerusalem 1971

    Date of recording: Circa 1971

    Starting time: 2130 UTC

    Notes: The Israel Broadcasting Authority used to broadcast in various languages on shortwave in the early 1970's. Their English language transmission to Europe could often be heard well here in southern Ontario, Canada between 2045 and 2130 hours UTC on 9625 kHz. Here is a recording made circa 1971 as they concluded their program in English and switched to French at 2130 hours UTC.

    Many thanks to SRAA contributor, Liam Spencer, who shares the following recording and notes:

    Broadcaster: Radio Nacional da Amazonia

    Date of recording: July 16, 2025

    Starting time: 00:05 UTC

    Frequency: 11.780 MHz

    Reception location: Berthoud, Colorado, USA

    Receiver and antenna: Sihuadon D-808 with telescopic antenna

    Mode: AM

    Notes: Here's a recording pulled from my radio archive of Radio Nacional da Amazonia from Brazil on the shortwave frequency on 11.780 MHz from July 16th, 2025. What's interesting is that this was recorded on a weekday, and usually, back-to-back music is not heard on weekday evening programming. Along with the announcers who are usually high energy are not in this recording. Around 20 minutes in, I stopped recording and resumed recording at 01:05 UTC until the end of the recording.

  • V32 Persian/Farsi Numbers Station: March 16, 2026

    Many thanks to SRAA contributor Dan Greenall, who shares the following recording and notes:

    On March 16, I listened to V32 using the SV1BTL SDR in Athens, Greece. The voice came on at exactly 1800 UTC, but right up to 1759, the bubble jammer was being heard on that frequency. There did not appear to be any jamming during the actual "broadcast". The signal was very strong, averaging 20 dB over 9. At 1823 UTC, there were 12 users listening on this particular SDR, and 8 of them were tuned to 8742 kHz!

    I made the following recording (March 15, 2026 at 1822 UTC on 7842 kHz USB)) of V32 using a Kiwi SDR in Alvito, Italy. The "tavajjoh" (3X) announcement comes around the 6:09 mark, after which the numbers seem to run together more, rather than distinct groups of 5.

    Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:

    Broadcaster: Xing Xing Guangbo Diantai (Star Star Broadcasting Station)

    Date of recording: March 16, 2026

    Starting time: 2358 UTC

    Frequency: 19.052 MHz

    Receiver location: Thailand

    Receiver and antenna: Kiwi SDR with Wellbrook loop

    Mode: Single Side Band

    Notes: This is a "numbers station" broadcasting in Mandarin Chinese, presumably sending encrypted messages to Taiwanese intelligence agents in mainland China, from Taiwan. It appears to follow a set daily schedule, and begins each transmission with the tune of a Chinese folk song played on a flute. This is followed by station ID, given twice, and a few announcements in Mandarin, then a sequence of numbers read in groups of four. An excellent article about this station can be found on the Mount Evelyn DX Report written by Rob Wagner VK3BVW in May 2025.

  • V32 Persian/Farsi Numbers Station: March 13, 2026

    Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:

    Broadcaster: V32 Persian/Farsi numbers station

    Date of recording: March 13, 2026

    Starting time: 0226 UTC

    Frequency: 7.842 MHz

    Receiver location: Israel

    Receiver and antenna: Kiwi SDR with MLA-30+ Active antenna

    Mode: Single Side Band

    Notes: Background material obtained via Radio Free Europe / Radio Liberty.
    This radio signal first started broadcasting on February 28, about 12 hours after the United States and Israel began bombing Iran.

    A man's voice can be heard speaking Persian, counting out a series of apparently random numbers. The numbers are read out for varying stretches of time, followed by a pause in which the word tavajjoh -- which translates as "attention" -- is spoken three times. (around the 48 second mark in the attached recording)

    Beginning on March 4, the signal started to be jammed, with a cacophonous screech of electronic noise that made it all but impossible to hear the numbers. The original transmission paused for a period of time, then moved to another shortwave frequency.

    The transmission, that has been dubbed V32 by at least one group, is called a numbers station, a Cold War-era tool that employs radio transmissions and old-school cryptology to transmit secret messages, usually to spies around the world. It's location is suspected to be somewhere in central Europe.

    The attached recording of V32 was made on March 13, 2026 around 0230 hours UTC on 7842 kHz upper sideband USB using a Kiwi SDR located in Israel. I began the recording on 7841.9 kHz, but switched after a few minutes to 7842 kHz. This will account for the change in voice pitch.

    Also attached is a brief recording of the jamming signal, or “bubble jammer”, made on March 6, 2026 on 7910 kHz (V32’s original frequency) at 0218 UTC.

  • Polish Radio External Service (Via WRN and WRMI): September 26, 2025

    Many thanks to SRAA contributor Liam Spencer, who shares the following recording and notes:

    Broadcaster: Polish Radio External Service (Via WRN and WRMI)

    Date of recording: September 26, 2025

    Starting time: 02:59 UTC

    Frequency: 9.455 MHz

    Reception location: Berthoud, Colorado, USA

    Receiver and antenna: Sihuadon D-808 with telescopic antenna

    Notes: After the withdrawal of most Overcomer Ministry broadcasts in the Summer of 2025. WRMI began relaying the World Radio Network North American stream to fill the empty hours. While this is great for many shortwave listeners, as we get to hear stations that used to broadcast on shortwave again. WRMI isn't making any money from broadcasting the World Radio Network, and it is unknown how long these will last. On September 26th, I recorded the Polish Radio External Service, as they became part of my daily listening thanks to WRMI. I used a cassette tape to record the broadcast. Sometime during the recording, a few seconds of the broadcast were cut as I had to flip over the tape to continue recording.
