Good evening! I'm a GMRS user from Georgia. I may be traveling to Aiken, South Carolina in the coming weeks. I've located a "Aiken 575" GMRS repeater 462.550 (Permission Required). Is that repeater still active? If it is active, who do I contact to get permission to use it? Are there any other GMRS repeaters in Aiken or the area? Is GMRS popular in the Aiken area?
