There's some hiss in analog

I haven't heard any rumbling but I'm over a hundred miles away
down here on the border, and on the other side of the station from you
so it could be something up your way.
There are a few times when it seems I hear a transient echo but I think
that the audio version of temporary digital corruption (QSB related?)
like what would be seen as pixelation when it occurs on TV.

The data is supposed to have error correction. Maybe the errors are
exceeding the maximum rate. If the system is engineered correctly you
should not be able to hear problems due to errors but what is done right
in IBOC.

The hiss doesn't go away for people that don't have HD, oh, like
someone listening on a AR7030+. It isn't that the radio sidebands are
so wide that they are getting the HD noise (OK, signal) because you
can select a narrow filter on the 7030. Not all IBOC stations have
this problem, so it could be pilot error of the broadcast tech that
set it up.

Now the poor schmuck using a car radio, which doesn't have tight
filters, has to put up with the IBOC noise. So they brickwall the high
frequency content of the analog, add noise, then tell you it is for
you own good. This is so nasty, Dick Cheney must be involved.

"FCC to Consider Raising FM-HD Power Levels"

"Why would radio stations take the risk of degrading the quality of
their existing analog service in order to pimp a flawed technology
which nobody's listening to? It's almost as if the strategy of the HD
Radio Alliance is to degrade analog radio service in order to force
digital adoption - kind of a variant on the 'we had to destroy the
village to save it' rationale."

iBiquity is trying to force digital adoption.

Talk about confusion! Good way to promote a product * let them think
they already have it! Struble you¹re a genius.

Oh yea * hd radio is exciting! No need to buy one (if they were even
available) because you already have one!
KFI, always Johnny-on-the-spot, just fired their IBOC up. Resulting in
an annoying wubba-wubba sound whenever one of their sidebands fades a
little (which is several times a minute).
For some reason they sound especially bad on the AR7030+ now.

They sound OK here, full HD, still takes a few moments to have the HD
icon light up and the ID to appear in place of the frequency. Once the
HD locks in it stays and the audio sounds better even during QSB.


I'm in Canyon Country. Telemon's in Ventura. Where be you?

I guess I could connect the 75' random wire to the BA Recepter HD and
see if it'll lock. I've only ever heard one MW HD station (710 from
North Hollywood). The Mexican under KFI seems to be absent lately.

The radio is one of the Accurians that local Radio Shacks were closing
out recently http://tinyurl.com/dbl8db
I was using the small supplied loop last night hung from the ceiling
indoors and after fifteen or twenty seconds, sometimes less, it would
get a lock and hold it most of the time. I could tell when it reverted
back to analog because that's when the slight hiss returned, but that
didn't happen often.

You don't get KNX 1070 up there?

I can't recall hearing that, but I'm not a KFI regular.


KNX has some significant skywave cancellation here in North L. A.
County. The signal varies quite a bit, but is not steady enough for the
IBOC to lock. I get 570, 610, 710, 1220 and 1260 the best (in the daytime).
