[Elecraft] P3: Span limits move when changing bands

[AB4IQ]

I just went thru my 2 K3S's and K3 all attached to different P3's with my
cable attached to the P3's comm ports and for some reason do not have the
same issue.  My span limits on all three have stayed the same from 6 to 160
meters.  I'm using three different PC's with two of them using Windows 10
Pro and one using Windows 7 Pro.  I used Dxbase to change the frequency of
all three rigs from Cluster spots.  Don't know why mine doesn't have the
same issues.  Luck I guess..

I haven't noticed that large a shift, but sometimes 0.5 kHz or so.

the P3. It seems to be triggered when a frequency command is issued to the
radio via the P3 comm port. Is there any hope on the horizon for curing this
extremely annoying "feature"? There's absolutely NO reason for the P3 to
decide to change the span limits by itself once they've been set up on a
band. Maybe if we complain every couple of months someone at Elecraft will
take notice and get it fixed.

going from 7020 to 7040, if I go to another band and then come back to 40,
the span will now be 7025 to 7045.  Is this normal?  Have I missed a menu
option?

cursor is, but so far, I haven't been able to reverse engineer that.  I'd
really like it to retain whatever span window limits I've set for each band.
