Hi Joe - Do you have signal averaging turned on to reduce the noise floor? If
you do, it has to stop averaging when the freq is being changed while tuning,
temporarily raising the noise floor slightly. It then re-starts multi-pass
averaging once you stop tuning. This is normal for signal averaging. I run with
averaging set =2 or 3 passes. When I tune I barely notice a small increase in
the noise floor.
If you have a lot of local pulse noise, you might want to turn on the P3s NB
function to help.
If Averaging is turned off, I can't think of a normal scenario where the noise
floor would go up when tuning the band. It certainly does not here.
Anyone else have any ideas?

I have been using a P3 with my K3 for the last two weeks and not happy with it's
operation. I set the parameters to what I like, the patterns look
good, but when
I tune the screen fills with noise and you can not see the signals up
and down the band.
I am told the SVGA option does the same thing. Have owned radios from
Apache Labs and Flex
and used the SDR-IQ/SpectraVue and LP-Pan panadapters and all of them
do not have
this problem. On SDR-IQ/SpectraVue the pattern smears some when
tuning, but no noise.

Has anyone compared the SDR-IQ as a panadapter with the P3?
I am using the SDR-IQ now but would like to be able to use my entire
computer screen for other displays during contests.
