Since Wayne has returned from the holidays and the P3 Freeze is on the
list, here's a little more "data" but not necessarily "information" ...
I have never observed the behavior being discussed on the P3 Bug thread.
I have always observed the following:
Select band 1 [doesn't matter what band], set REF LVL to put the noise
on the baseline. Waterfall background is black, signals show up white
[I'm in monochrome WF mode].
Select band 2 [doesn't matter what band], set REF LVL to put the noise
on the baseline.
Re-select band 1. The noise will be above the baseline by about 10 dB
or so and WF background will show the noise. After maybe 2 seconds,
noise shifts down to the baseline and WF background goes black.
Happens every time I change bands, regardless of how I do it [BAND UP/DN
on K3, band buttons on KPA500, or typing a frequency in the N1MM entry
window], and it always has.
I don't think it is related in any way to the discussion but one never
knows with software. During those 2 sec, it appears the P3 is receiving
and displaying a valid spectrum, just offset above the baseline. It's
not a problem for me, I consider it normal operation and it is what it
is. But, just in case it's relevant ...
