The mic with the problem is an Electrovoice RE15 on a boom with its XLR connection going into a HOSA splitter cable, TRS on the KX3 side and two XLR connectors on the other.
I suspect it's a wiring problem. The RE15 is a dynamic pro mic and is balanced; pin 1 is the shield, Pins 2 and 3 are the signal pair. To connect any balanced dynamic mic to an unbalanced input (virtually all ham rigs) connect either side of the pair to the shield and to the sleeve of the Elecraft mic connector, connect the other side of the pair to the "high" side of the Elecraft mic connector. It's easy to make an adapter cable. Start with a female XLR3 connector and a male plug that mates with the KX3. A piece of RG58 or miniature coax like RG-174 work fine as a mic cable.
