Doug,
Not sure what the first paragraph has to do with filter selection on the K3?
Using the 1st IF output one bypasses all filters and the DSP 2nd IF
completely. I know because I do that for both main and sub-receiver
on my K3. I use two LP-Pan (one for each IF).
You do not define "Full" in spectrum. I suspect you mean you use the
full bandwidth of your soundcard or the funcube. This is 192-KHz for
the best soundcards that I am aware of. 190-KHz is full bandwidth
for my SDR-IQ. Do not know what is possible with a fun-cube.
Full spectrum for my station is 100-KHz to 26-GHz; only display that
will cover that for me is my old surplus HP141T spectrum analyzer -
max scan spectrum is 200-MHz wide with the mw plug-in starting at fo =1500-MHz.

On my K3 I have an LP-Pan connected to my IF out on the main receiver and a
FunCube Pro on the subreceiver IF out. The LP-Pan is setup to a Steinberg
USB UR22 sound card. Therefore, I have two panadapters, one through Win4K3
for the main receiver, the second using NAP3 v5 to the funcube pro.
This give full spectrum display. I say this, because my normal operating
