Mars Hill PD and FD both utilize VHF frequencies listed in the database. Madison County EMS uses VIPER after dispatch on 155.100 (county fire/EMS). Unfortunately, VIPER isn't used much in Madison County except during major events, land searches, etc. The primary VIPER users are NCSHP G1, USFS, Mission Health EMS (which contracts as Madison County EMS as well as running Critical care transports), and MAMA medical helo.
