p3 fixed mode center does not stay stuck across band changes

Howdy,

I have a problem with the way my P3 is working. I'm inclined to call this
a bug, not a feature.

If I set the P3 for fixed mode, 100 khz span, center at 18.118, great, I
can see the whole of the 17 meter band. If I change bands with the K3 band
rocker button, go to 20 and then back to 17, the center remains where it is.

However, if I change bands with the computer, for instance with WSJT-X, to
20M then back to 17M, then the center gets set to 18.150 -- I can no longer
see the bottom 32 KHz of the band until I adjust the center again.

I'd really like to see this fixed.

Thanks

Jeff

Re: p3 fixed mode center does not stay stuck across band changes

This behavior bothers me too. It appears that if you issue a frequency
command directly to the K3 the P3 will always reset its span limits. For
some reason, issuing only a band change command doesn't cause the reset.
It's probably a "feature" but it's one I'd also like to see modified.

Re: p3 fixed mode center does not stay stuck across band changes

It annoys me too. I haven't yet figured out exactly what it is doing
and what causes it and it seems like it isn't always repeatable. What I
really want is for the P3 to maintain the SPAN setting and CENTER that I
manually set for each band. I run 20 KHz spans on CW on most bands [30
m is at 50 KHz], and if I place the span on even 20 KHz boundaries [e.g.
14020-14040, I'd like that to be maintained with freq/band changes.

Re: p3 fixed mode center does not stay stuck across band changes

Coincidentally, those are exactly the settings I like to use. I find
that if I QSY from 14030 with a with span center of 14030 (limits of
14020 and 14040) and return It will go back to the proper center. If I
do the same from, say, 14029.6 it will invariably come up with limits of
14025 and 14045. Weird.

Re: p3 fixed mode center does not stay stuck across band changes

In reply to this post by k6dgw

What I have noticed is that in fixed mode when you set Center/Span by a
macro, the change is not permanent and will be lost on a band change or
power cycle. But when you change either of those with the knobs, the
change will be remembered.

I use macros sent from DXLabs Commander program to set and reset a
"pileup mode" in which the dx station is moved near the left edge of the
screen and the span is reduced. If I go to another band the P3 will go
back to 'normal' state. If I know I am going to be doing this I will
manually change the parameters slightly back and forth in order to force
them to be saved.

Since I can easily send the macro to enter the special mode or reset
everything to normal, this hasn't been a problem for me.
