Hey all,

I've been searching to no avail. I need the full pinout for the RG45 connector for the speaker/mic/program outlet on the radio. I need to make a cable to interface with a clear-com intercom system. Can anyone help with that?

Thanks!
-Geoff

Same as the Maxtrac except with 10 pins instead of 8. Pins 1 & 10 are special, and definitely used with the keypad mic. Pins 2 thru 9 match older series of radios.
