That's what IBOC shills would have you believe, but it has been
demonstrated many times now that this is not the case, and that
significant sideband interference from the IBOC sidebands is caused via
skywave at nighttime. Please note that it takes a significantly smaller
signal to cause interference than it does to actually HEAR the signal
itself. Because of this, those IBOC sidebands can and do interfere with
stations in an area where those same sidebands would not be copyable.

True, and add to that the directional effect of the typical AM loopstick
antenna. For example, a person might be listening in the evening to,
say, WLS with the station in the antenna's near null area. This is no
problem if the signal strength is good and the interference is low. But
the antenna in that position is likely to be near broadside to the WCBS
transmitter and the listener will get the extra noise.
