[Elecraft] P3 v. SDRPlay RSP1A for panadapter

[Barry]

Bill,
     That is a interesting question. I use the RSP for spectrum display 
and LP Pan with a good sound card for CW Skimmer; Yes, they are in 
parallel. I would say there is an advantage to using a software spectrum 
display vice a P3; my feeling is that there is more flexibility. I run 
my spectrum display, Win4K3, as a way to tie all of the software I use 
together for tracking and control and logging.  If you go with the P3, 
you will still need some software to integrate station functionality.

     The real question is just how much spectrum do you really need to 
display. About 100 KHz works for me most of the time. That means a sound 
card that samples at 192 KHz. should be adequate, but there is always 
the desire to see more, whether you really need it or not. It's been a 
while, but as I recall I can see about 1 MHz. using the RSP. For chasing 
DX in split mode, I usually run about 50 KHz on my 24" monitor. This way 
I can see where the DX station is hearing. The way you operate will 
dictate what bandwidth you will use and when.
