The design of the GM300 can be traced back to the Maxtrac, and much of the background material for the Maxtrac applies to the GM series. If you look at this page <http://www.repeater-builder.com/maxtrac/maxtrac-index.html>, one of the notes says "On any radio that is new to you do NOT assume that any accessory connector pin programming is present, or if it is there, is correct for your environment." Are you certain that your radio is programmed for COR? Mike WA6ILQ
