If I were to set up a favorites list for NCSHP Troop F Dist 2 which is TG 52190, along with sites Deep Gap mtn, Doughton mtn, Green mtn, Jefferson mtn, Phoenix mtn and Pores Knob. Would that allow me to hear dispatch as well as cars? Also would I only need to program the control and alternate control channels for these site? The unit i'm using is a Hp1 and the zipcode scanning seems extremely inefficient.
