[Elecraft] KAT2 - Bridge Null Adjustment problem

[Sanger, Joseph]

Well, my KAT2 saga continues.

 

I did indeed find some unsoldered pins on one of the relays, and
corrected this.

 

Now, however, I seem to have the opposite problem.  When trying to
perform the CALn procedure, instead of having too much reflected power,
I now have no power (forward or reflected) at all; '000' shows all the
time on the LCD display, no matter what I do to C55 does and no matter
what the Power level is set to.  The DC voltages on the REFL and FWD
signals paths are zero now.  I have checked and rechecked for solder
bridges, cold joints and shorts/continuity on the RF cable and control
cable, and am running out of ideas (and my sanity)!
