Well, you can avoid most IBOC interference at the moment by nulling
it away with your no doubt directional antenna. With multiple IBOCs
on the same frequency that won't work, of course. And you may
already be using your null to take out another station on the same
frequency, which hobby will disappear.
Also the IBOC hash is much stronger on the sideband away from the
offending station, so use LSB to listen to 770 hashed by 760's station,
and USB to listen to 750 hashed by 760's station.
