AM HD is stereo.

AM had stereo first, way back in the past. It was so good, the FCC
approved
first one, then FOUR different methods for stereo modulation. Holy cats!
The FCC actually thought there might be enough consumer demand to support
four different AM stereo plans. The broadcasters and manufacturers all
jumped in, as well.

Broadcaster's weren't "on board" with the marketplace aspect of picking a
standard.

The "let the marketplace decide the stereo standard" was one mistake that
the FCC didn't make with HD. They named a standard, and all the brodcasters
are on board with the same standard.

With no standard chosen, there was no impetus for the public to buy one
standard over another, nor impetus for manufacturers to start making one
standard over another....in any real sense.

Problem was, people didn't like stereo enough to buy another radio. And
it's not as if the radios were real expensive. They wouldn't buy four AM
stereo standards. They wouldn't buy even one.

They WOULD buy one...IF they knew *which* of the four was the one to buy!
So they waited....and did nothing.

Actually, people didn't care much about FM stereo, either. FM stereo
didn't
reach mass market appeal until it was almost a give-away with the radio.

That's what will happen with HD. Until it starts being included in the next
radio people will purchase, or in the next car they buy.

There might be a lesson there for HD radio. Give it away and maybe people
will listen. But I really doubt ibiquity will give up licensing fees on
their patents and copyrights.

Well, Volvo is making all their 2009's include HD as standard equipment.

Other manufacturers are including it as an option, and I'm sure some people
will buy their cars off the lot with it included without them having to
chose it specifically.

Lucky for Glenn, if he ever does start living in the past, he can look
back
at a lifetime as an accomplished DXer and radio broadcaster.

I'm sure his kids will be impressed.
