[Elecraft] P3: Span limits move when changing bands

[Fred Jensen]

I think that may be a clue Ed, my K3 is ancient [#642] but has current 
FW and new synth.  The computer connects to it and the P3 connects to 
the K3 serial port ... otherwise fixed-tune mode wouldn't work.  I've 
never seen the issue when changing bands with the BAND U/D switch, or 
from macros executed from the KPOD, only when the commands start at the 
computer and go thru the P3 to the K3.  N1MM+ is the only control 
software I use.
