One is enough. If skimmer is really needed, and you want the panadapter and the ability to drive various programs, you get LP-Pan instead of a P3.
A P3 was made so someone with ONLY a K3 and a P3, WITHOUT a PC, could have a panadapter. The P3 was not designed as a do-all for all things SDR. Elecraft may get around to some add-ons, like IQ output from a P3 or some such, but those are business decisions. A K3 had a very clear, specific intention to begin with, which it brought to life very nicely. 73, Guy. On Mon, Aug 29, 2011 at 2:34 AM, David Gilbert <[email protected]>wrote: > > > OK ...
