Hi,
Hopefully someone can help. KPA100 tests went OK so I assembled the amp
into the existing K2. All seemed OK but now I have lost Rx on all bands.
Problem exists when I re-install old lid and remove all option boards. Yes
I know that W1 is removed for 160m board. Shunting this makes no difference.
Tests seem to indicate a short across J4 on the K2 RF board. I tried the
trick for resetting the relays. In reset Pins 2,3 and 4 are shorted
together, Pins 2 and 3 because they should be and I assume Pin 4 through
the turns on T4. In reset, the resistance from center conductor of J4 to
ground is 1726 ohms (this seems OK through R67 and R68). Is it likely that
I have a bad relay? How would I tell? Any other clues?
