451.2250 114.8 is the Eddington Repeater
457.7000 is a Link from a remote mtn top in East Eddington
Next time it's active, see if you can figure out what it's linking from (another freq)
462.4000 156.7 is also a link, from Seal Harbor
451.1500 is the Repeater in Lincoln
451.1750 is one of 3 possible Repeater sites
Dover-Foxcroft, Machias or Seal Harbor
461.0500 is licensed for a Trunked site, but could be a Repeater out of Franklin
This may help to start you out. I hear talk on these the most and I have a general idea of what areas they cover.
Bangor District (Covering greater Bangor and Brewer area)
451.225 tone 114.8
Machias District
457.7 tone 69.3
Lamonie/Ellsworth District (covers Bar Harbor and MDI as well)
462.4 tone 156.7
Unknown (I have heard crews in towns near Lincoln)
451.15 tone 141.3
Unknown (I have heard a crew in Millinocket)
451.175 tone 82.5
Unknown (I have heard talk but had no idea where they were.)
461.05 tone 114.8
I also believe the "truck #" they ID on the radio has to do with the district they service. I believe the 100's are Bangor and 300's are Ellsworth. I have not caught on to the others yet.
