[Elecraft] P3 Config Question

Short answer" No.  That said, you really want the long answer :-)

A great number of the P3 settings, like a K3, are on a per band basis. 
Change the band, and it remembers the settings for that band.  In the 
P3, much of this is because what works best on one band may not work all 
that well on another.

The 8 programmable function keys aren't enough for a selection of 
various options [like 2 SPAN's] and other parameters for each band. 
Everyone runs it different:  For me, globally:

Always fixed-tune mode
Full-screen shift
Spectrum Avg = max
WF mode = monochrome
WF Avg = min
FN1 = 200 KHz span
FN2 = 100 KHz span
FN3 = 25 KHz span
FN4 = 4 KHz span
Amplitude scale = dBm

I've still got 4 unused FN keys. :-)

I use full-screen shift [the whole next span when I tune off either end]

I use monochrome WF because I don't have any color vision, however 
several guest ops whose color vision is normal note that they can spot 
weaker signals in mono than they can with the color display.  I'd 
recommend you try both.

REF LVL:  The reference level will change from band to band and from 
time to time on the same band.  It is a reflection of reality ... that's 
what is really happening on the band, baseline noise [and noise 
characteristics for that matter] change with time, and we normally like 
the noise at the baseline.

Monitoring signals on the bands, the spectrum amplitude will NOT reflect 
the S-Meter.  You can calibrate it with a signal generator of course, 
but with max averaging in the spectrum, it won't directly, 
quantitatively follow the S-Meter.  That too is normal.

I bought my P3 as a toy never guessing that it would end up being what I 
look at while operating.
