I purchased a Uniden BCD325 P25 with DMR key for a gift and trying to program. It is for my elderly Mothet and all she wants to listen to is the local law enforcement, fire, and EMS. I have the simple instructions from Uniden that I can follow but I am not sure if I should use conventional, P25 standard trunk, Dec/TGID or P25 one drew trunk. I live in Putnam County Tn. Help!!!
