[Elecraft] P3 v. SDRPlay RSP1A for panadapter

[Barry]

Dave,
     I know I am not the greatest writer on this reflector, so let me 
clarify something. I do use the RSP for spectrum display, but that 
display is by using Win4K3 which can be driven by the RSP. To me it was 
just a chance to add to the collection of "stuff" I have on my operating 
desk and computer.

73,
Barry
