I can only help a little.
Caribou Fire Dept is still using 453.250 PL 71.9 (channel 2).
Caribou Highway Dept has gone MotoTrbo (It used to be 154.22, but I didn't bother to find out if the frequency is the same)
Presque Isle Police (155.040) and Fire (154.385) Departments are both now MotoTrbo.
I don't believe anyone in the state is using 33.90 anymore.
Washburn is using both those frequencies and I believe 154.085 PL 192.8 is primary. (156.210 PL 151.4)
I believe that The Sheriff's Office dispatches all the smaller Fire Depts on 154.055 with different tones for each town. They normally test daily between 4:30 PM and 5:00 PM with a separate call to each town. Some will answer and some won't.
"xx Fire this is a test, only a test. Aroostook clear at (time)"
Unfortunately, I don't have my external scanner antenna hooked up due to lack of funds, although it is mounted in place so I can't pick up the tests from home.
