Hi I am working on a kenwood ts-430s and the radio is not keying up with the desk mic but is with the send switch, anyone know what pins to jump on the mic plug to force this radio to key so I can check and verify it is the MC 60 microphone that is causing the issue, Thanks

Well, by jumping pins 2 and 8 the transceiver is not keying up is all I knowOMG really? google kenwood ts-430 mic wiring and you immediately get 5,000 results with the answer.

exactly. simple process of elimination. are all the controls set properly? mox switch keys radio, so that tells us the radio's keying circuit works and radio does in fact tx. test mic with vom, is it good? bad? you say jumping the tx/ground pins on the radio does nothing. are you connecting the correct pins? double/triple check. if yes and still no tx, first course of action is obviously to inspect and test the radio's mic connector, mic connector wiring, and circuit board connections. if mic is faulty fix or replace. block diagram the diagnosis and repair.
