Hope someone can help me. I have a bearcat scanner. I'm trying to monitor Baltimore County police. I feel like everything is programmed correctly but I do not pick up any transmissions for Precint 3 (pikesville). I hear calls for every other precint. Does anyone know if Pikesville is somehow encrypted? I dont see how the scanner could not pick up this one specific talk group 9603. My understanding is that on a trunked system the entire county shares the same set of frequencies. Is their something unique about the Pikesville precint?
