According to the article WWFD shut down their analog AM Signal recently and it happens today. Note WWFD is running a trial here.
In Washington DC, WWFD 820 AM The Gamut will be the first full time, all-digital AM radio station in the U.S. In an effort to keep up with the ever-evolving demand for digital, The Gamut will be turning off its analog signal and will no longer be accessible through regular AM radio beginning today, Monday, July 16 at noon. This announcement comes as a result of a collaborative effort between The Gamut and HD Radio, an Xperi Corporation brand, to give AM broadcasters parity in the car dashboard with FM HD Radio, satellite and internet streaming, among others.
“My belief is that AM needs to start trending in this direction,” said Dave Kolesar, the station’s engineer and program director. “We’re excited to be doing this extremely innovative project that has tremendous potential to make AM much more viable to distribute all formats.”
“Since the launch of HD Radio technology, Xperi has been committed to serving the current and future needs of terrestrial radio broadcasters,” said Joe D’Angelo, SVP broadcast radio, Xperi. “Hubbard’s decision to convert to all-digital operations illustrates the industry’s continued commitment to over-the-air broadcasting and a long future for broadcast radio. With twenty percent of the vehicles on the road in the listening area equipped with an HD Radio receiver, the time couldn’t be better for an all-digital trial.”
How is this different than the IBOC AM signals currently on the air? Will the lack of the analog audio make the digital signal more robust? I wonder how the fringe area reception will be affected? If there is no improvement to the reception of the HD radio signal they should have kept the analog for the 99% of radios that can’t receive the digital.
While my car radio has HD, I had to spend extra $$$ to get it, the stock radio did not have HD.
