Kenwood has the pin assignments available on their web site.  (www.kenwood.net.)  They give the pinouts for mics, and many of their accessory cables/plugs.

    The "Standard" Kenwood 8-Pin assignment:

1  Mic audio
2  PTT hot line
3  DOWN button (not applicable in your case)
4  UP Button     -- ditto --
5  8 Volts, limited to 8 mA max draw
6  No connection; sometimes connected to receiver audio out in some radios.  (Easy for Packet TNC connections!)
7  Mic (audio) shield/ground
8  PTT ground.

    So you would use Pins 1,and 7 for mic audio, and 2 and 8 for the PTT switch on the MC-50.

    Not sure how the original MC-50 4 pin was wired, but that shouldn't be too difficult to figure out, or get from the Kenwood site.

Good luck!

P.S.  If sent by e-mail, the info might help you.  Posted here, with the question, it may help others also.

I have a friend who has recently gone blind and wants to use a hand mic. instead of a desk mic., for obvious reasons, on his Kenwood TS530. The problem in doing this is that, the MC-35S 50K  4 Pin Mic. is no longer available.
Looking at the possibility of using one of the more recent mics via a matching transformer. Can anyone help with information or, dare I ask, have an old MC-35S Mic "kicking around"?
