I don't. Why do you think they'd be turning it off now when they just
started night time AM HD broadcasts?

Maybe cause nobody is listening? Or, possibly interference
complaints? Makes sense to me.

Yeah, I'm puzzled at your question as well. If radio stations have
just started turning on HD why would they turn it back off again?
They won't have meaningful audience statistics to base a decision on
for several months.

There would be no audience statistics that showed whether night HD was good
or bad, just as there are none for daytime operation.- Hide quoted text -

d'Eduardo,

Since the vast majority of AM/MW Radio Listeners still have
Analog "Only" AM/MW Rados -and- Since Nightime IBOC
Broadcasting makes Analog "HD" Radio Painful to Listen to :
Expect the numbers of Nightime AM/MW Radio Listeners
to start Dropping as more and more AM/MW Radio Stations
begin IBOC Broadcasting at Night.

The Tombstone of AM/MW Radio does not read "RIP"
it reads "IBOC" ~ RHF

Once Again I Ask Myself : What IBOC ?
All I See Is The Blinking Blue Light ! ~ RHF
In That Distant Land* Where IBOC Fears To Go :
Life Exists and Radio Listeners Live Beyond the 10mv/m Contour.

They know no one is listening - they just want to jam adjacent-channel
competitors off the dial and hope they will cave to HD Radio.

Nobody in Columbus Ohio is broadcasting HD at night, with about 3 stations
with it in the day. WOSU 820 WTVN 610 WCOL 1230 (or whatever they're
calling themselves now).

Actually WCOL might be using it but nobody would be able to tell, at night.
Nobody can hear it.

They should sound killer within 15 or 20 miles of the transmitter.

No, the limiting thing is what else you can hear, not what
their power contours are. There's a thousand skywaves on the
frequency just as strong, at night.

That's the benefit of having a clear channel and contour protection, which
no longer applies on most frequencies.

I'm very familiar with the graveyard freqs. I enjoy listening to KOY
at night when I'm in Tempe. They have a pretty much identical setup
as the Columbus station.

Ya know, Hybrid Digital Radio has an option for 20 kilohertz wide
channels (the center 10 for AM, and the adjoining 5 kHz sidebands for
HD).

If the stations simply switched from 30 kHz mode to 20 kHz mode during
nighttime operation, that would help minimize interference to the
skywaves.

(But no the FCC lackeys never thought about that. Dummies.)

I noticed that KFBK 1530 had very bad noise bands at 1520 and 1540
for about the first three or four nights and then they disappeared. I
hear 1520 loud and clear again.

Several have, when they found the night antenna system was not broadband
enough for good HD performance.

Here's an interesting thread:

"Can't hear you any more at night"

"The complaints are starting to come in from people about not being
able to hear the 50KW non directional clear I work for.. at night.
They appear to be 40 to 100 miles from Xmiter. This is not good. We
used to be heard in 37 states...Now we are lucky if it is 37 counties
at night. Many of these locations are in the total survey area. Hope
AM...at night..dies real soon!"

It amazes me how ****ing stupid broadcasters havre been for buying
into iBiquity's bull-**** - and to think, that broadcasters have put
total faith into this antiquated, destuctive technology to save
declining broadcast radio! Yea, we will buy enough crappy, expensive
HD radios that can't pick up ****, but when they do it is just ****,
to keep broadcasters (those of the HD Radio Cartel) afloat!
