Based on the county designations in their TG list, would you say 306 is TAC 1 and 307 is TAC 2?
Everyone seems to be going off the PowerPoint presentation. Please note that there are talkgroups on this system that were not on the presentation...
That being said, 306 is ECI dispatch - not a TAC channel. 307 is a TAC channel - so that is TAC 1. TAC 2 or "Frequency 2", although not on the new system, remains 155.220 MHz analog.
It's no different than the other departments...
Erie Fire has a dispatch channel, and TAC channels.
Millcreek Fire has a dispatch channel and TAC channels.
West/South/East fire departments each have a dispatch channel and TAC channels.
The dispatch channels for those are not considered TAC 1 - and neither is EmergyCare dispatch (306).
