WWFD in Frederick, Maryland, is the only all-digital AM station in the USA. Switching to HD Radio’s MA3 mode, there’s no longer an analog AM carrier; the signal is only digital, and any AM-band HD radio can decode it. Dave Kolesar is the energetic engineer who has driven this switch to an all-digital AM transmission. He and Mike Raide with Xperi join us from the WWFD transmitter site – and bring us a “first ever” surprise at the end of our show!
