Yes. It will all but eliminate selective fading distortion and replace

sync detectors are capable of this. You can't listen to an IBOC station
in ECSS either.


If such a station was far enough away to present fading
wouldn't that be far enough to render the sideband noise a moot issue?


The digital stuff is in both sidebands and 180 degrees out of phase with
itself. A simple detector sums to zero; a selectable sideband detector
hears the digital crap along with the analog.
