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.

I don't have P3, but I do use the RSP. The RSP works great, but when
switching in filters, your display will offset by the offset value
included with your filter. If you are using Win4K3, compensation is
done for you, but other software (ex. HDSdr) does not. For me this
isn't a huge issue as I don't do precise tuning using the panadapter.

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.
