I can hear IBOC crap on the analog signal. It's very low level, but
you can clearly tell when a local station is using the hash generator.
Also, the bandwidth goes to ****. The analog signal when IBOC is
running is just barely better than a phone line.

If your receiver IF/Mixer isn't completely flat you'll hear the IBOC.
The digital sidebands are out of phase with each other and the system
relies on them cancelling out in your receiver. You can't use a synch
detector on an IBOC station, unless you can listen to both sides at
once.
