[Elecraft] LP-PAN 2 and P3

[Don Wilhelm]

Jorge,

The goal of both the P3 and LP-Pan (with PC software) is the same -- to 
give you a panadapter display of the IF output of the K3 (K3S) or any 
other radio.

The P3 does it by direct digital means and displays the resulting 
spectrum and waterfall on the native screen.  With the SVGA option, it 
can display the same information on a larger SVGA monitor - no computer 
is involved.

LP-Pan is a hardware box that takes the IF output and produces I/Q 
quadrature audio outputs.  Those I/Q outputs must be sent to a soundcard 
and processed by a computer running SDR software (HDSDR, Win4K3suite, 
NaP3, etc.) to produce a spectrum display and waterfall.

If you are trying to decide between the two solutions, consider the 
"computer or no computer" considerations.  LP-Pan requires a computer to 
process the I/Q signals, but the P3 (with or without the SVGA option) is 
independent of an external computer.  The P3 with SVGA option simply 
provides a larger display on an SVGA monitor (no computer involved).

If you are willing to deal with 'computer things' like soundcard setup 
problems and software application setup problems running on the 
computer, then LP-Pan may be an OK solution for you.  However, if you 
want something that can provide a panadapter display without dependency 
on a computer, then the P3 would be the best choice (with or without the 
SVGA option).
