Hi Paul
Thanks for looking into what is really a minor issue.
Here's what I see with my setup: K3 6299, P3 2380 with SVGA
(which I think I ordered at the same time as the P3). P3 is
powered from K3.
The K3 is running:
MCU 5.38, DSPs 2.86, FP 1.25, DVR 1.03
The P3 is 1.60 SVGA 1.34 and SpanScale is OFF. (I noticed this
issue with earlier versions of the P3 firmware.)
The span on 80M is 100KHz and on 160M is 200KHz.
I power on and set 160M Ref Lvl 96, switch to 80M and note that
the Ref Lvl is 111.
Power off and on with the K3 power button.
Radio is on 80M and Ref Lvl is 111.
Switch to 160M and Ref Lvl is 96.
If I change SpanScale to REF LVL only and repeat the test:
I power on and set 160M Ref Lvl 96, switch to 80M and note that
the Ref Lvl is 111.
Power off and on with the K3 power button.
Radio is on 80M and Ref Lvl is 111.
Switch to 160M and Ref Lvl is ***111***.
For completeness, I tried with SpanScale REF LVL & SCALE and the
160M Ref Lvl was also 111. SpanScale is certainly part of the issue.

BIll,
I just cannot duplicate that here on the bench. I am using
version 1.60 in my P3. Here are the steps that I do:
1) put the K3 on 160 meters, and then set the ref level to say 126.
2) put the K3 on 80 meters and then change the ref level to 145.
3) power cycle the unit.
4) go back to 160, and check the ref level. It is in fact 126.
Question, what is the span on 160?

Paul,
With SpanScale ON, if I power cycle with the radio on 160, the REF LVL is
restored correctly. If I
power cycle with the radio on another band, then the 160 REF
LVL is not restored correctly. I’ve never seen this happen
for any band other than 160.
I need SpanScale more than I need remembered 160m REF LVL, so I’m content with
this small issue.
Thanks for the note about the serial command.

Hi Bill,
Regarding the serial command not saving the span: there is a known bug in the
P3 with saving the
span when a serial command is used. This will be available in the next release.
Regarding 160 meters not saving the ref level correctly: it still sounds like
the ref level issue
is with SpanScale. If you turn off spanscale, does it fix the problem?

Paul,
Interesting. I too see the failure to remember REF LEVEL only on 160. And I
need SpanScale turned
on.
Perhaps this is related: when I set SPAN using the #SPAN command, change bands
on K3 then change
back, the SPAN I just set is not remembered. This does work as expected when I
use the P3 buttons.
Or maybe this only happens to P3 owners named Bill :-)

Hi Bill,
Make sure you have SpanScale turned off, and then try it. I just tried it
here on my bench units. I put the K3 on 160 and set the RevLvl to 139 (it's
noisy here). Then power cycled the radio and P3. The P3 came up with 139
on 160 meters.
