Been listening to KDKA AM radio in digital. What a crappy signal. It
switches back and forth from digital to analog and during the
transition the receiver makes this screech noise that sounds lik/ the
receiver isn’t resolving the digital signal correctly. When in full
digital the high frequencies are so dirty sounding, I guess due to the
slow bit rate, that I have to ask myself, what’s the point? When it
goes back to analog the signal cleans up and sounds great. Tell me
again why would anyone want this?

Are you sure that your problem isn't related to the signal bouncing between
the Pittsburgh Macaroni Co. and Wholey's in the Strip then off the Roberto
Clemente Bridge and then ricochetting around Sliberty and the Sou-side and
finally ending up somewhere in Wilmerding?

So if he's experiencing multipath distortion
then maybe his radio isn't at fault after all?
I get QSB type path deterioration (not multipath) on the KFI 640 signal from
L.A. such that I periodically lose HD sync, but there's no "screeching"
artifact, just the presence or absence of hiss.

The sky wave and the ground wave are at odds with each other. I listen
via the web.


I get the same phenomena with KNX 1070.
Would like to try KGO 810 but they kill their IBOC at night
before the band opens up that far away.
If you have an HD receiver maybe you could test your reception
of our KOGO 600 up there on your end, It runs IBOC 24/7.

I have a local on 610.
