I liked the AM-on-FM-subchannel feature, which allowed me to hear
a so-called local Imus affiliate finally. I see no point in
additional FM channels for music though. It's the same junk as
the regular FM.

And of course Imus is gone now, so that edge is gone.

AM HD radio is annoying even when it works ; like vinyl records,
AM has a pleasing sound on its own, and this just destroys that
slight advantage. In addition, it drops in and out of HD when
a thunderstorm goes through, which is beyond annoying and you have
to search for a station carrying the same program without HD.

Then there's the HD hash, but that's been discussed to death. I'm
just talking now about HD when you're listening to the HD station.

Keep the FM subchannels, throw out the rest.

HD and DRM may be different technically but share commonalities in how
they degrade in less than perfect conditions. Both systems do not have
enough margin built in to make them an actual improvement over analog.
The almost endless BS by some posters and economic interests has been
hard to take. These systems do not use enough bandwidth to actually have
improved sound. These systems do not have enough redundancy to have
adequate weak signal or interference protection. HD and DRM sound
quality and reliability just plain suck.

I posted this years ago that these systems do not fit the medium in that
they do not transfer information in a more reliable manner that analog.
There is no improvement using HD or DRM over analog as a result.
