Loxahatchee NWR

From a long time source in South Florida:

172.2750 MHz confirmed as U.S. Fish and Wildlife Service, Arthur R. Marshall Loxahatchee National Wildlife Refuge, in Palm Beach County. FWS personnel from Loxahatchee also administer Hobe Sound NWR, but I don't know if another freq is used up there (in Jupiter, FL). Input to 172.2750 MHz is unknown at this time.
