Hello Maryland, I'm have recently loaded Somerset and Worcester Co. EDACS systems into my 163 and have not heard nothing. The reason I loaded them is because one night this week at 10 pm I was hearing multiple Wicomico TG's such as MSP Salisbury, Wicomico Sheriffs Office EMS 2 FG 2E , I loaded them in just for fun. I have the frq's set for EDACS put them in as in the LCN is listed and loaded the TG's correctly, still haven't heard anything , just curious?
