Just an update in case anyone is every looking to wire up to a M600. No one sells just the mic plug. Icom sells the microphone wire for $60. Replacement microphones on ebay for $90.


Someone in Taiwan was selling that $30 cord and thats what I bought.


My original mic had the following wires - white, exposed, black, red


New mic cord from taiwan had - yellow, brown, black, red


I wired a 4 pin male to the other end so I can use whatever 4 pin mic I want.


Icom wires = Astatic Wires


yellow = white

brown = blue/shield

black = black

red = red


Wired up no problems and tested with Astatic and Turner mikes.


Also - M600 radios aren't great for tuning for ham use BUT they are 100% duty cycle so pretty burly radios. Also can be expanded to cover 10 and 11 meters.
