An associate who does not live nearby has a Motorola System 500 CM555 40ch AM/SSB Base that he is searching for the mic wiring pattern for. He does not have an ohm meter and cannot test it out himself. Says it is a typical 4 pin plug.

I can't anything about this rig on the net.

Anyone know the mic pinout on this one?

Thanks!

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
