I want to program some new frequencies and talk groups but they are part of a huge phase 1 network system that has 30 frequencies listed Only 3 are listed in red or primary control channels. Do I add multiple frequencies? Thanks
You most likely need to add talk groups as long as you have the control channels programmed.Do I add multiple frequencies?
You shouldn't have any problems. Just program all of the primary and alternate CC'sGreater Cleveland Radio Communications Network System

The PDF file is just a list of the frequency and talkgroup information you need to program the scanner manually. It is still far easier to enter that information using software. I am happy to provide you with any help you need.Here's the link for FREEScan as @tvengr recommended. It's FREE and will allow you to upload his file to your scanner.
