Z3 board came loose and probably damaged. Removed and soldered a jumper re Elecraft support. We have power.

Nothing on receive yet. Triple checking on the tmp cables etc as I have had the radio apart many times.

AGC, pre amp seem to have no effect. Receive on the xvter board is also dead.

Ken,

first-aid idea (as you said both RXs dead and Cal failed...) :

1. Turn ON K3
2. On the K3 front panel, hold CONFIG menu and turn tech mode on (CONFIG:
TECH MD ON).
3. Tap MENU to exit the menu and then tap DISP on the K3 front panel.
4. Rotate the VFO B knob to display SYN1 in the VFO B area of the display.
You should see the
status OK. the same for SYN2 status OK after...

If there is no OK status of both synths then check the all TMP coax cables
from and to the synths boards and check if synths boards seats well in the
multi-pins headers...
