Without ANY interference to 1'st adj? I can't see how. Even if the station 
squashed it's own audio to 5Khz, then ran 4 Khz of "hash" (5.1-9khz from 
carrier) it would *still* interfere with the 1'st adjacents.

The only way it could *not* interfere would be to see all AM's limit their 
analog to something like 3Khz, then run the hash between 3.1 and 4.9. That would 
be about the only way I can imagine a hybrid mode could exist that causes no 
interference *on special radios*. While many AM radios do roll off at 3Khz, 
they aren't brickwall filtered there.

Boy... now you're *really* lost me! ;) Rich has been very successful for a 
long time. Radio has been programmed with all kinds of different formats for a 
long time. I cannot even begin to fathom what you're talking about, here.
