I have a couple of HR-2510s that were working fine when they were put
the shelf, but now neither one of them are working. One
transmits won't receive the other one is locked on one frequency and
won't change to another frequency. Both of these radios worked fine but
have been setting on the shelf for a couple of years. Anyone know of a
common problem to this model that might have caused both radios to fail?

Yes, they're in the hands of a CB'er.

Happy to help.
