If you have any interest in playing with a Repeater CTCSS "Tone Panel"... here's the deal of the moment.
Ebay Item 220627865813 COM SPEC REPETER TONE PANEL Starting bid: US $20.00 If nothing else you could tack it onto the disc (in some cases even the low level recorder) output of your scanner for a visual of the tone in use. Hope someone gets the great deal... s. And no, I don't have anything to do with the auction... I'd buy this auction if I didn't already have one (actually more than one) of these units.
