I just got a low band HT750 on trade and want to monitor NCHP & DOT I40 Winston Salem to Hickory and I77 Charlotte to Surry county area. I know that NCHP is going or on VIPER system and I think I have there low band channels right ,but DOT channels i'm not so sure about. They are listed by district and I don't have a district listing to go by. I would like to monitor IMAP in Statesville area(I40-I77) and Mooresville area if not on 800. I looked at the RR listings and don't see IMAP in these areas. Thanks for any help you guys may be able to give.
