When I program the frequencies in my scanner for the Viper tower in Cherryville I get no reception, no hits on the control channel. I assume this tower also is a site for Gaston/ Mecklenburg system as they list a Cherryville site but have no problems with those frequencies after I reband my scanner. However, the frequencies for Viper are dead silent. I live about 15 miles away from Cherryville towards Shelby but can’t get anything when I’m in Cherryville. Does anyone know why this is?
