Pittsfield Fire Operations are usually on 154.3400 PL 107.2. Some units are repeaterized, others aren't.
They rarely switch to fireground, only for intra county ops, and when they do, they use 154.1600 PL 107.2, which is the county-wide fireground.
I have never heard them use 154.22. I think it's used more for administrative use.
Do you have an address of the fire on Waconah Ave?
