[hpsdr] Horton with Trumpet??

[Murray Lang]

Actually, the CAT etc stuff was a bit of an afterthought. I was trying to 
think of ways to reduce the per-client bandwidth down from the full sample 
to whatever the immediate requirement is. Polling of the rig might work 
since only frequency changes that take it out of the current segment will 
need to be reflected back to the server. There are lots of tricky problems 
with the concept but it's all off topic anyway.

Does moving the filters help because of PCB space or calibration? If it 
opens a can of worms then maybe separate signal generator board project 
would be simpler.
