Chicago's WIND is a curious case. They went to IBOC a couple of months
ago.
I'd think a station like WIND would be just about the last station to
adopt
IBOC, because it's at the low end of the dial - 560 kHz, and uses a
directional antenna to broadcast from Northwestern Indiana to Chicago.
Getting the necessary 45 kHz bandwidth on a directional antenna at the low
end of the dial seems to be an engineering worst case scenerio.

I understood this has something to do with the Q-factor of the aerial, is
that correct?
You actually need a bad aerial for IBOC :-)
