Not sure who I'm talking to here, no signature, no call. It's a little
hard to explain but ...
Assume you set SPAN=100 KHz and put the left edge at the bottom of each
band. Changing bands back and forth using the BAND ^/v switch will
preserve these settings, and every time you come back to a previous
band, they will appear ... so long as you don't touch any of the P3
controls. However, using CAT commands [e.g. from a logger], you can
change to a new band and the settings will hold, however returning to
the previous band, the SPAN will still be 100 KHz but the center
frequency will have moved and the left edge will no longer be at the
bottom of the band. Admittedly, it's a bit hard to duplicate but the
circumstances that cause it are common in contesting and it has been
duplicated by several folk, including me.
The issue has been raised here on the list more than once. I think it
first came up several years ago, which could be 1 or 6, even Apollo 11
seems like yesterday to me these days. [:-) It has some of the earmarks
of an intentional attempt to "do something good" in the firmware which
turned out to be not so good, but I really don't know. For whatever the
reason, I expect it to come back to the settings it had when I left that
band.
As Randy said, it is really annoying. I, and I think most, use the P3
visually instead of looking at the K3. If I set the left edge at the
bottom of the band and the SPAN at 100 KHz, I automatically visualize
the 1st 100 KHz directly from the screen. If it's changed as a result of
band changes, my mental picture of that band segment is wrong.

Hi,
What exactly do you mean?
It is always set to whatever you send. If you explain this a little more
perhaps I can help.

Subject: Re: [Elecraft] P3 center frequency
It's been brought up several times in the last two or three years. No response
from the P3 software guys. It's EXTREMELY annoying that the P3 won't respect
the center frequency setting if the radio is tuned via any CAT command. I've
given up on hoping it will ever be fixed. My guess is that it's all hands and
the cooks working on K4 software these days.

Jim: In general, yes, if you change bands with BAND ^/v. When you
change bands via the CAT, the P3 center freq won't always end up where
you last had it. I believe SPAN width is preserved but the span
limits show up strange. It's a known issue, has been discussed at
some length here a few months ago.

Should the P3 center frequency and span be remembered when changing
bands?
Rephrasing, can they be remembered when changing bands?
