Anyone know the current status of the HD radio implementation that has

How long will it take fior the noise to stop, etc?

I have a Yamaha 4600 receiver and JVC car radio with HD radio.

On AM, only 1190 KEX broadcasts in HD. KEX is a talk radio station
with little stereo content. A few commercials are in stereo and
they really jump out. HD audio sound quality is similar to analog
on a 680NAB tuner.

Quite a few FM stations have HD. I listen to all classical KBPS.
Sound quality is indistinguishable between FM and HD except for
the noise floor. KBPS compresses the HD signal just as much as
the analog signal.

The non HD AM reception on the JVC car radio sucks. Reception is
weak and the audio is poor. HD sound is fine, but the least bit
or powerline interferece knocks the radio back to muffled analog.

HD FM on the JVC car radio is weak, dropping back to analog at the
slightest provocation.

I would like to see a Ramsey kit am transmitter with HD.
