It is possible to get the radio to tell you what tone it is set on. I'd have to
go play with it to see how. If you just want to match a tone of a received
signal, set the second from left button to one of the tone settings and hold in
the function button until it beeps. It will have set the tone frequency to the
frequency in the signal that you're receiving.
