The IBOC signal is either side of the AM carrier. Each IBOC sideband is
identical but out-of-phase with the other. The theory is the IBOC
sidebands cancel each other out in your receiver. But if one sideband
propagates better than the other (which is always the case once you get
a few miles from the transmitter) the cancellation is not complete.
This is when you hear the digital hash and the wubba-wubba sound.

For those of us using a radio with selectable sideband synchronous
detection, but unable to choose USB and LSB at the same time (like my
Drake SW2) we are forced to listen in plain AM.

Clear Channel has 2 full blown flamethrowers crippled by IBOC in
California now. It's a shame. Citadel gets it. KGO and KKOH do not
use IBOC at night. KFI and KFBK do, and it really diminishes their signals.

They sound terrible in either side band selectable sync turned on with
the Drakes. There is significant low frequency noises that are not
easily describable along with the usual high frequency hiss. Kind of a
low frequency rushing sound like water through a pipe. This sucks.

Now the only radio I have they still sound halfway decent on is the
RX340 with its brick wall DSP filters. I can barely hear the low
frequency noise and the high frequency hiss is minimized in AM mode.

So here is the upshot:
The worst sound is on the Drakes with side band selectable sync turned
on. Next worse is with the AM sync on so the best is just AM mode with
no sync. Same for the AR7030+ except it does not have the selectable
side band sync. The best is the RX340 where both the low frequency noise
and the high frequency hiss is not as prominent.

I'm complaining to KFI about this.

I got a response from KFI already. Their online technical person Ernie
Kristof said he would pass my comments along to the chief engineer Terry
Grieger.

If you don't like the IBOC signal then tell the stations about it. If
they get enough complaints maybe they will turn it off.

Their programming sucks worse than their signal.
Biggest improvement KFI could make
would be to get rid of Dr Laura and Rush.
Then bring back Tom Leykis.

Dr. Laura is very abusive with callers.

I can agree on Dr Laura. Rush I listen to once in a while. Usually when
I decide to listen to him there is usually a guest in his place. Just
luck I guess. Tom Leykis belongs under the biggest rock on the planet in
a very dark place.
