I've documented all the county fire dispatched homes in Pitt county. The only way I knew to do it was Record when the tone went off and then use a program that's free on the Internet and decode the frequency (in HZ). And then put these in my indication G4 pager and they all worked great. I do listen to Washington, and Beaufort County but I don't have any tones for any of the stations there. But this is one way you can do it.
