TWiRT 555 - Aerial Measurements, Military Precision with Phil Larsen

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 accuracy and integrity of the measurement results.

TWiRT 554 - Tower Tales with Tom Ray

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 solved as well.
