The secret to the SC Palmetto system is knowing what is on each tower. I've monitored Laurens Co from South Cove area of Oconee Co. I now monitor Hwy Patrol dispatch in Greenwood from Furman Univ North of Greenville. This allows me to hear cars sign out at McCormick Co and thats a VERY long haul. First program the Hogback tower [# 17] and run it as a Wildcard to see what you get. Then try the Ceasers Head twr [31] the same way. Then try the Paris Mtn twr [#35]. If you just want Fire calls then use the simulcast 453.900. It would help if you posted the type of antenna and coax you use. 800 MHz is delicate and the connectors, coax, and antenna must all be correct. Good Luck, Larry
