I just checked the Repeater-Builder Kenwood section that discusses the various microphone wiring schemes http://www.repeater-builder.com/kenwood/kenwood-misc-connectors.pdf for different Kenwood Ham rigs but, no information on commercial radios. Does anyone on this list happen to have a schematic diagram of the KMC-18 DTMF microphone with the modular 6-pin connector on it??
I would like to adapt this mic [change the connector to the 8 pin type] to my Kenwood 440 UHF TM-441A radio. The 441A rig requires a 600 ohm impedance mic [I have the stock factory one but its a little beat up]. It is assumed that the KMC-18 being a Kenwood product, is a 600 ohm mic. Thanks!!
