I recently put all the VIPER control frequencies (per RadioReference.com) in a bank on my PRO-96 and have been monitoring, including on a trip from Kernersville to Goldsboro and back over the Memorial Day weekend. I was receiving SHP base station transmissions on several talk groups monitored with control channels from Stokes, Guilford, Orange, Alamance, Randolph, Wake, and Johnston counties, but it seems clear the mobiles are NOT being run thru repeaters as has been my experience with all other trunked systems I monitor. My guess is that the control channels "control" the transmit frequencies for the mobiles just as if they were being repeated. I have no idea what they use for car to car unless they are still using the old low band transmitters. Does anyone have any info on this and/or if they are transmitting on the trunk frequencies is there a way to get the PRO-96 to "listen" to the selected transmit frequencies for the mobiles as well as for the bases?
