I had my agency program the PRO-2096 I bought. We use a multi site trunking 800 digital system. Im also a ham operator so I have more knowledge than most on radio ops. But this kinda confused me. When they programmed my scanner via computer they put several different sets of frequencies into one bank. About seven or eight tower sites for my area. Each set obviously has a control channel. With that control channel comes about six other frequencies programmed in. I read a thread posted earlier about needing ONLY the control channel for each tower site programmed in. So I programmed in the control channel to the three sites I can receive from my house. In between each control channel i put in an 800 mhz conventional channel because of what I read earlier. Before I programmed those three myself I was missing a TON of traffic. Can anyone fill me on why in the world I only need control channels plugged in instead of every frequency for that tower site?
