Never happen - radio will always stay analog

Well I hope your wrong. I'm really enjoying these extra channels.
For example, my local FM station has just added a "Remix Top40"
channel which is basically all the current hits, but in a dance
format.

Cool.

And my Christain station has added "Gospel" on HD2 and "CCM for Teens"
on HD3.

Cool.

And my Rock station has added "Classic (60s-70s)" and "Indie Rock" to
its HD2 and HD3.

Cool.

This is what digital radio is all about: Increasing the number of
choices available to listeners. How can you possibly sit there and
say this is a bad idea for FM Radio?!?!?

SFTV,

AM/MW "HD" Radio is 'by-design' Engineered to Interfer
with the two Adjacent AM/MW Radio Channels at 10 kHz.

Study the AM/MW Radio Band Plan.
{ 10kHz Channels }

Study the FM Radio Band Plan.
{ 200kHz Channels }

They are two different schemes : IBOC will work in one
and trash the other.

Digital radio of any flavor will suffer from the propagation
characteristics of the MW band. Let's leave AM well enough alone, and
use a tiny sliver of some of the reclaimed UHF TV spectrum or maybe an
old VHF TV channel, some band with more predictable and stable
propagation characteristics. I think that it serves the public
interest to reserve a tiny bit of spectrum for something other than
cell phones. Then again...

I really believe that mobile internet will supplant all of this anyway
within 10-15 years.

There is no single FM station that covers the entire Bay area
completely, and programming quality and relevance is the most
important issue.

AM is still useful and viable. The fact that it is being mis-
programmed in many markets shouldn't cause anybody to condemn the
whole band. If you serve your listeners and advertisers well by
creating unique content that people want, and distribute it in ways
that listeners want, you can do very well. I fully expect that our
'content' will become more available via many distribution channels
over time.

Newspapers are fighting similar battles right now, and are expected to
'invade' radio's turf with audio and video programming. I expect that
the content provided by newspapers, radio and TV will become more
merged and similar.
You'll see more "on demand" programming, and have many more listening
options. As broadcasting becomes more 'internet like', listeners will
expect audio and video content availability to be more internet like
as well, with many options (real-time "live" streaming, "on demand"
and the availability of individual program elements for inclusion into
personal and customized "playlists").

It's going to be a bumpy ride, but if anybody is paying attention,
we'll all be better served.

The stations that should be really concerned are the ones doing a lot
of syndicated programming. They won't have anything to sell once
distribution isn't limited by broadcast channels. If these guys want
to stay in business, they'll have to come up with some unique content,
which should be local. Generic music 'jukeboxes' will have similar
challenges, though there is certainly room for them.

That is because radio markets are defined by the listenership to stations.
If the three AMs that keep the far reaching counties or split counties
(Contra Costa West) in the "market" decline significantly, the market will
be redefined. Several dozen markets are redefined every year, adding or
losing counties. Since AM listening is declining everywhere, if the sum of
KGO, KCBS and KNBR decline to a certain point, and no longer represent a
significant portion of listening in certain counties, Arbitron will redefine
San Francisco and more FMs will cover most of the market.

Yeah, news talk and even sports (Detroit, yesterday, in fact) are moving to
FM.

Actually, many of the jukeboxes have talent driven music shows that are, in
the mind of listeners, just as local as the ageing news and talk stations
that have not moved to FM.

Is this what you learned when you attended Yale?

Shut HD the f##k off, period... whoever made the decision to allow nighttime
operation should be hung in public.

characteristics of the MW band.

Please explain why that is? I don't understand. After all, we
created modems operating at 30+ kbit/s over very nosiy analog
telephone lines w/ only 4 kHz of bandwidth. If we could do that, why
couldn't we use similar techniques for noisy braodcast channels?

Just curious.

propagation characteristics. ...

I like that idea. Maybe a DAB system at around channel 51 and up.
Each of those channels is 6 megahertz wide, and DAB uses ~16 channels
of 1.5 megahertz each, so you'd only need to setaside UHF TV channels
51, 52, 53, 54, and maybe 55.

BTW:

You can't use "an old VHF TV channel" because VHF is already occupied
by TV channels 2 to 13. For example Philladelphia uses 2, 3, and 6.
And my local area uses 8, 10. Baltimore area uses 10, 11, 12, and
13. There really are no "unused VHF TV" channels.



I really believe that mobile internet will supplant all
of this anyway within 10-15 years.

Perhaps. Personally I'd rather have both. AM/FM bands (and maybe
DAB) along with wireless internet for my cell phone.
