I was mostly curious why the CM500's mic produced the hum, but the handheld mic that came with the KX3 didn't. The CM500 has a quite long cable, and I wondered if that could be part of the problem.

Any one or a combination of the various issues I noted. Your observation about your finger on the coax connector suggests bonding and/or adapters that aren't doing what you think they are.
