TWiRT Ep. 561 - Home Studio Perfection with George Whittam

9/11/2021
George Whittam is one of the foremost engineers building home studios for radio, TV, and Hollywood voice-over talent. Many of his clients were doing some work in their home studios prior to the COVID pandemic. However, the lockdowns of the past 18 months - particularly in California - have made it absolutely necessary for the quality of home studios to rival that of commercial facilities. This is where George’s expertise has been proven time and time again. "Home Studio Perfection" is what...

TWiRT Ep. 560 - Streaming Success in 2021 and Beyond

9/2/2021
It’s been well over 20 years since some radio stations began streaming their audio on the Internet. And these days, most stations do have a streaming presence. But, is that enough with so much competition? Is there more in terms of convenience and utility that we broadcasters can provide to our listeners? Ed Martinez, Robert Minnix, and David Bialik sure think so - and hundreds of radio stations agree. From automatic content archiving to instant rewind and even “access control” using...

Phil Larsen used to fly drones to pick up bad guys discussing their evil plans. Now he runs the QForce Airborne Division of QCommunications, listening to radio and TV stations while measuring transmitted signal patterns. Aerial signal measurement has been around since an engineer carried an RF field strength meter into a helicopter. But, today’s measurements using custom-built drones are far superior to earlier methods. Phil explains what goes into drone-based RF measurements to assure...

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.
