I rechecked the pins on the relays [ugh] found a donut solder joint
reflowed it and two others Did the power calibration...
Display in tune is now 5.6F 0.0r voltage on DMM is 9.90vdc

RC,
Re-do the power and SWR calibration, and then try it into a 50 ohm dummy
load. Tell us what you find.
I know that is not an answer to your total problem, but there has to be a
starting point, so verify that calibration first and we can go from there.
In case you cannot achieve a good calibration, it may be that there is a
relay that is not operating - usually due to an unsoldered relay pin. I
know it is difficult to check those pins because they are under the
inductors and capacitors, but it may just have to be done - we will see
after you re-do the calibrations.

Hi gang
Having just finished building a KAT2 for K2 #5804
and I'm at the point of doing the checkout and
calibration prior buttoning it up. Every thing
checked okay until I got to POWER calibration
R1 & R2 when I go to TUNE my display reads
" 7.3F 6.8r" I also get a HI CUR displayed when
first activating tune. My DMM reading off of the
DL-1 are less than .5 vdc
