Chris Tarr just finished a long-anticipated FM transmitter move. Big implications attended this move all the way across a metro area. The new site needed a directional FM antenna, and they decided that a new transmitter made more sense than moving the old one. Chris covers a lot of ground when contemplating any transmitter site move.  Kirk Harnack touches on a few pointers for IP radio microwave links, including not trusting the existing infrastructure too much!

Show Notes:

1. Planning Transmitter Moves

   1. Facilities - Building, road, fencing, parking, HVAC, roof, ice protection

   2. Legal including FCC

   3. Permitting - local zoning, building, etc.

   4. Safety - fencing, insurance requirements, guy anchors, tower base

   5. STL considerations & options

   6. Frequency coordination for 950 & IP STLs

   7. Fiber internet availability

   8. AC Power - service sizing, etc.

2. Executing the move

   1. What can be built and ready beforehand

   2. What has to move overnight or a weekend

   3. Absolutely no off-air time? Or minimal?

   4. Actual cutover

   5. Moving audio processing if needed

   6. What if something goes really wrong? 

   7. Plan to go back if needed?

3. After the move (should have been before the move)

   1. Tying up all the loose ends

   2. Grounding, lightning protection

   3. Putting redundancy in place at the new location

   4. What if Internet installation is late?  Wait or move ahead?

Search the web and you’ll find hundreds of articles videos - and thousands of opinions - on the best mics to use for radio and podcasting. One of our sponsors is Angry Audio, makers of two novel mic processors to improve and control the sound of two popular microphone families. Our longtime friend and colleague, Cornelius Gould, designed the audio processing algorithms behind these specific mic processors. “Corny” joins us to talk about this rather unique approach to mic processor design and implementation. Plus Tom Ray pops in to discuss microphone choices with Chris Tarr. Plenty of opinions and some solid advice!

Show Notes:
Cornelius Gould is also the founder & host of The Rocketry Show podcast.
The mic pre/processors for which Corny wrote the algorithms are the REbel & SMooth from Angry Audio
Tom Ray’s microphone is a PreSonus PX-1 condenser mic with a dbx 286s processor
Chris Tarr is liking his Electro-Voice RE20 with a RØDECaster Pro
Kirk is currently using a Sennheiser MKH 416-P48U3 with a PreSonus Revelator iO24

Transmitters of all sizes and from several major manufacturers. The most recent transmitter replacement is at WZYP-FM in Huntsville, Alabama. Market Engineer, Dominic Mitchum, is taking care of much of the local work and logistics, alongside Robert’s work. The project also includes replacing the RF coaxial transfer switch, main coax, and even the main and backup FM antennas.  Robert and Dominic give us a very informative video tour and discussion of this project on Capshaw Mountain. Plus, Chris Tarr relates his own recent transmitter installation experiences and has developed some advice on purchasing used transmitters.

Over 50 years ago, Mike Dorrough introduced the Discriminate Audio Processor - the DAP 310. Broadcasters that cared about audio quality started buying and installing DAP310s to improve the audio quality of their stations. Five decades later these old audio processors are still in demand - as are services to supply parts and repairs. Randy Swaffer and Mike Phillips are two DAP310 enthusiasts - and they know all about repairing and aligning these classic units. Jordan Tuck also joins us to talk about refurbishing other broadcast gear, including a Continental Electronics FM transmitter and an A-6000 audio console.

Most broadcasters either own towers or lease antenna space on them. But only the tallest towers are outfitted with elevators to bring workers and light tools up to desired working levels without spending half the day getting tired from climbing. Jim Tiner is CEO at Tower Elevators Systems. His company has built many towers - short, medium, and tall - and many of the tallest ones also have a custom-designed elevator system. This elevator technology is often applicable to other tall structures, such as bridge towers, smokestacks, and even the Statue of Liberty.  Jim Tiner presents his company’s fascinating story and tells us about unique elevator designs.

Most of us in radio have heard Fresh Air, hosted by Terry Gross on National Public Radio. Joyce Lieberman was the first technical director behind this well-produced national interview program. But Joyce’s engineering and production career started several years earlier, getting a kick-start when some other engineers called in sick. At the onset of Joyce's radio work, she recorded Terry Gross and her guests when Fresh Air was a local Philadelphia three-hour program. Her attention to audio purity and detail prepared Joyce for other audio engineering achievements, including working with a team at WHYY and NPR to restore and digitally archive the episodes of Fresh Air, plus provide guidance to other archival efforts. Chris Tarr adds his expert insights as well to this interview with Joyce Lieberman.

Show Notes:
Joyce appears on another podcast, Working Class Audio #304
More information about Joyce is found on this page about the SZALON Tech Team

Current technology education and career advancement are both available at the SBE Ennes Workshops, offered at the NAB Show in Las Vegas.  The dates are April 12 & 13, just prior to the NAB Show Expo Halls opening. We’re talking with David Bialik and Fred Willard, who have assembled what appears to be the most useful and beneficial set of programs in two technology tracks.  There’s an RF101 Bootcamp track. And the subject of this TWiRT show - the Media Over IP track.  Watch the show and click on the link to SBE’s full description of these technology tracks. This is a very worthwhile 2-day workshop for any level of broadcast engineer!
