This might also just be a general question for the scanning forum, but I was curious about this system. I know that there are multiple sites for this TRS. In the RR DB there is only one control channel listed. Is this a control channel for the entire system? If this is the case, then I guess one could just enter that frequency in as well as the TGs that I want and the CC Only would handle the rest right? I am actually from Roanoke, VA and we don't have multiple sites, but I have lots of family from that area and wanted to know before I head down there next time.
