I monitor the Floyd County fire dispatch (Greenville, Georgetown, Lafayette....etc) and I often hear them say switch to channel X. Are these other channles/frequencies that they use the fireground channels? I recall several years ago stumbling upon some "fireground" frequencies somewhere on the internet, but have not had any luck finding them again. Does anyone know what other frequencies the Floyd County fire uses other than the main one which is 154.130? What about Harrison County? They also swith to other channels from 158.745 which is their main one. Thanks
