I live in MA. I have the Pro 97 which is a handheld version of your scanner. If your banks are set to open it will pick up any and all talk-group Ids. You need to set the bank to closed and it will pick up oly the ones you have programmed. As far as control channels I only programmed one site per bank using the control channel only. You can program the alternates but is not needed. What software are you using to program?
