I have a RS Pro-163 that I have programmed with a Motorola Type II Hybrid system. 4 control channels and 169 talk groups. I had originally programmed it in the conventional manner with the control channels and voice channels. I was not aware until reading the Wiki on CCO that it would scan in that manner. What are the advantages and disadvantages, if any, in CCO? I am listening, at the moment, with it programmed that way. Any input is appreciated.
