I was listening today and heard a couple of Alpharetta units refer to PD TAC3. I knew about TAC1 and TAC2, but wasn't aware they were using a third TAC channel. I tried to scan for it but couldn't find it. Anyone know what the talk group info is for Alpharetta PD TAC3?
I am not aware of an Alpharetta TAC 3 on the Fulton TRS, however every radio has a conventional 800mhz simplex channel which can be used to talk from unit to unit without using the TRS. In order to listen in you would have to be within a mile or less of the actual radio. Dekalb does this but they refere to it as talk around.
Also another posibility is that they were using a fire TAC to speak to AFD.
Is it possible that they're using one of the I-TAC channels? You might monitor those as well. I know that Cobb Fire uses them on the fireground but you might have to be reasonably close to monitor.
