The other day I heard the Medford Mass A2 unit talking to the Armstrong dispatcher on 463.525. I am pretty sure that Armstrong Ambulance Service dedicates 2 ambulances to covering 911 calls in Medford. "A1" is a 24/7 ambulance staffed by paramedics. "A2" is possibly a 12 hour per day ambulance that is staffed by EMTs. It seems that the Armstrong BLS ambulances operate on 464.025, and the Armstrong ALS units operate on 463.525. But for some reason, I heard A2 chatting on 463.525. Peter Sz
