Hold on your scanner and directly enter your control channel frequency, you should be receiving a signal and maybe (I can't fully remember) static noise.I am not receiving a signal from the Taylors Bridge site (03-65) in Sampson County and have not for a day or so. I have tried doing a search of the 700s and 800s used by VIPER and can not find that the site has changed the CC. I am receiving all other sites in my scanner normally.
Also, check to make sure you're running "NAC Search" (if your scanner permits it) because the NAC can change
