In the past half hour I've been getting continuous, long (over 15 seconds), tones on this freq I had in my scanner as, "Cumberland County Fire". It was analog mode with a CTSS of 107.2 I'm pretty sure this is an old frequency possibly not used anymore, but someone is this morning. Anyone else heard this too? I am located in Gray. 5x5 signal here. Maybe just some technician working on it? Any thoughts?
