I am looking at purchasing an MB1 transceiver. Just doing some ground work on connecting certain hardware to the radio. I have a HM-12 microphone which is currently connected to a Kenwood TS-990S. It requires a 4 pin XLR Female connection to the Kenwood. But I see that the microphone 1 connection is a phono plug. I assume that it is a 1/8 inch phono plug. Or it might be a 1/4 inch plug. They give the size in mm, but not too sure what the size really is. Any help on finding the necessary cable to connect my microphone to this radio would be very much appreciated.
