BAMM!!! Thanks Steve, that's the way my thoughts were going in 
this endeavour, and that is exactly what I'm wanting to do.
Nothing more than an Osc., the audio source, the DBM, and the
USB crystal filter to feed the PA, making up what might be
described as the most barebones, simple way to transmit
certain digital modes as a LOWfer.

Anyone else have comments along this line ? Sure would like 
to read them.
