John Lyons was a not only a fixture, but a force, in the New York City RF scene. His tireless work - especially after 9/11 - has gotten and kept radio and TV broadcasters on-the-air with excellent engineering, optimized coverage, and reliable operation. With John's recent passing, today's TWiRT features Chris Tobin and Tom Ray - both of whom worked with John extensively. We'll also enjoy John's presentation about Building the Advanced RF Transmission System at One World Trade Center.
