[Elecraft] P3 - Question

[Alan Bloom]

It could be a lot of things, but I would first suspect the cables.  The
BNC cable from the K3 to the P3 is easy to check if you have another one
to temporarily swap.  There is also a small-diameter cable inside the P3
with "TMP" connectors on each end that connect the rear-panel preamp
board to the front-panel board.  You might try making sure the connector
is well-seated on both ends.  Press the connector in with a twisting
motion.
