The benefit of AM HD is much higher fidelity and stereo akin to an FM analog broadcast.
Digital FM is equivalent to CD-Quality and you can have at least three stations on a signal. I've picked up that many from the Detroit market when there is an incredible band opening here into Mid-Michigan, but the local stations around here that have HD only have one alternate channel.

Well, as a number of us have commented on the list in earlier posts, it's
hard to see the benefits of A M HD radio.
I guess one of the benefits of FM HD radio is that you can get more signals
and diverse programming across the commercial FM spectrum, but I'm wondering
how much of a benefit even that will be now with the advent of live
streaming internet radio and the ability to get broadcast streams on smart
phones.
Time will tell, I guess.

Tom, I bought a Sony HD AM FM radio when they first came out. Here, near
San Francisco, there are afew FM HD stations and just a couple AM ones. I
haven't really checked it out that much recently. When I first got the
radio I tried to listen to KNX, a strong LA HD AM station at night using one
of those tunable loop antennas and even a kind of long wire. Seems like you
really have to have a strong signal to get the HD signal to work. I
remember one of our cars had AM stereo which was not much good, but on a
trip to BC one year, I could pick up some AM stereo from long distances and,
depending on the signal, the stereo would come and go. I think HD takes a
much more robust signal than stereo did. Also think that HD hasn't really
caught on that much or as much as the purveyers of it have hoped it would.

Thanks for the link, Steve.
I read the review, and found it very interesting. In fact, I've saved the
review here for future reference.
If I find myself to have a few extra bucks, someday, I may just buy one,
although in my area of semi-rural central lower Michigan, HD radio has not
yet fully arrived.
Would be interesting though to see what I could pick up in the way of HD fm
here from larger cities in my region, or HD am at night during the winter DX
season.
