TWiRT Ep. 554 - Tower Tales with Tom Ray

7/24/2021
Some days you’re the windshield, and some days you’re the bug. And some days you experience some of each. Tom Ray’s recent experience with a 4-tower AM directional array new New York is a study in “surprise” and “relief” as he dealt with half of a tower collapsing. These AM towers are in suburban wetlands, surrounded by residences, a city park, and protected waterways. Tom describes how, with a little luck and some expert help, a tower catastrophe got resolved and further problems were...

TWiRT Ep. 549 - Let's Move In Together with Mike Patton

6/18/2021
With urban sprawl, property values escalating, and AM stations having a more difficult time financially, sometimes it makes sense to combine one or more AM transmitters at a common transmitter site. Certain technical criteria must be met for this to happen, and combining AM directional stations can be challenging. Mike Patton has helped several AM stations move onto “common ground” and teaches about the key technical aspects to consider when combining transmitters.

TWiRT Ep. 548 - Combining FM Stations with Rob Bertrand and Andy Gunn

6/11/2021
Too many FM antennas on one tower? They’re (maybe) creating intermod products? No room or structure for more tenants? It may be past time to consolidate all the FM signals onto a master FM antenna. WAMU-FM and WTOP-FM in Washington, DC, did exactly this - and worked with other FM tenants on the same tower to create such a combined, master FM antenna system. Rob Bertrand, CTO, and Andy Gunn, DoE, tell the story and give us a tour of the combiner room at American University.

TWiRT Ep. 547 - Docker for Broadcasters with Cam Eicher

6/4/2021
Heads-up, broadcast engineers! Docker is coming your way. What's Docker? It's a brand name that's part of "containerized software" - and broadcast equipment is already moving there. Your audio consoles, talkshow system, and IP intercom can all run on PC or servers - on-site or in a data center. This is happening now! Cam Eicher with Telos Alliance gives a great tutorial on Docker containerized software and more on this episode of TWIRT.
