I have absolutely no dip in the center of my LP-Pan display and I have never
heard anybody else having this problem either. The IF out port and the
crystal filter bank are driven in parallel by a buffer amplifier that
appears to be capable of driving both without gain loss due to the crystal
filter load.

Knut,

That is because you are probably using one of the programs written 
for use with the LP-Pan.  They incorporate a shift in the frequency 
and probably that takes care of handling the filter issue (???).  I 
am using the LP-Pan with digital sw for eme which is not designed for 
the LP-Pan or the K3.  I am the only one using this equipment with MAP65.

I included my experience for anyone having a similar issue.  The 
solution is easy (read the original post).

Solution of the +6 KHz freq, offset in the LP-Pan LO was to install a 
different xtal in the LO (thanks to Larry, N8LP).
