I am using my 2m/440 ham radio to receive Jefferson Police (45.80 Lowband) on there link frequency of 453.0625. But I am only receiving the patrol cars and not the base. I am searching 5 mhz higher but I am not hearing anything. If anyone knows what the base link frequency is I would appreciate it. Please don't tell me me to get a scanner or another radio for the car, I don't have the room. Thanks!
