in ECSS either.

If such a station was far enough away to present fading
wouldn't that be far enough to render the sideband noise a moot issue?


The digital stuff is in both sidebands and 180 degrees out of phase with
itself. A simple detector sums to zero; a selectable sideband detector
hears the digital crap along with the analog.

Maybe next time I'm up in LA with a receiver, til then they're fine this
far away and the HD digitizing actually removes the path hiss.
FWIW: It's not the signal quality that keeps me from listening to them,
in HD they sound as good as any local. Don't listen to much AMBCB
I listen mostly to KUSS HD-2 or KPBS HD-3 in the FMBCB.


They degrade the analog signal used by 100s of thousands, while
providing crystal clear digital to a handful of nerds.

If those 'nerds' are the big spenders they target, so be it, it's up to
the sales dept to convince advertisers however.
IOW: If there's a well enough heeled benefactor to tote the entire
station's load they can program and configure to that person's taste.
Didn't there used to be some community service thing back before
unregulated capitalism came to town?

I've never seen an HD radio that wasn't on a radio executive's desk (or at
my house). Hobbyists and people in the "biz" are the only one's
interested.

Hundreds of your favorite broadcasters got their starts running Sunday
morning public service on local radio stations. I got 50 cents an hour in
1963.

So as to not miss a single nuance Dr Laura's wisdom?

Dr. Laura appears to have been replaced with more live Bill Handel. Weird.
