[Elecraft] K3 No Receive, No Transmit - SOLVED

[Guy Olinger K2AV]

The outer shell of the TMP plug can be connected without being fully
inserted into the TMP connector. This can result in an intermittent on the
center conductor that comes and goes with temperature change, or breathing
hard, or changes in phases of the moon. The little flanges on the TMP plug
should be nearly up to the TMP connector shell when fully inserted.

In my experience, myself and those around here who call for help, this is a
common trouble.

You could still be not fully inserted.
