I apologize in advance if this is absolutely the wrong forum to ask this question. I just came across a brand new Maxon CP-0520 UHF 2-way radio in my attic. It has a TX of 464.495, and RX of 464.545. I have no idea what this radio/frequency is used for. It's in such nice shape that I'd hate to just not use it or toss it. I'm not finding much information on the web, only parts and prices. Does anyone have any ideas? Thank you very much.
