All I know is trying to listen to weak station the next channel over
(10KHz) either way is impossible.


I don't doubt it, but I don't try to daytime DX near IBOC stations. Mark's
information is consistant with my observations from the early days of IBOC,
when IBOC was commonly used at night and there was a hole between the AM
channel and each of the IBOC sidebands in which a first adjacent might punch
through the interference.
