Good post, thanks. I have acquired a source for the control set and a key, still need to get a manual. That was already on my list. I had already spent about 6 hours reading through the material on that website and while it covers almost all the info on the GE's I could find nothing specific on why a radio whould need 4 (or more) 5C's and 1 EC. Do they take an average over several crystals or something or was this a function of multiple channels?
I am not interested at this time at putting up a commercial type repeater, only understanding them and the equipment better. I do not have the 5k+ needed to do a full blown repeater or the equipment (yet). A 440 emergency mobile repeater is my ultimate goal one day, but I have no time frame for reaching this, just a goal. I want to do it to gain a better understanding of repeaters in general. I do possibly have access to people that has several repeaters up and linked in the NC area, but they are at least 3 hrs away. All of those are GE or Motorola. They would be my source at first, when the time comes, for some of the specific programming and testing equipment that is so expensive.
