Orange Coast UHF Repeater Association

The Orange Coast UHF Repeater Association (OCURA) began as the Bucks-Lehigh UHF Repeater Association (BLURA) founded in 1974 to serve the radio amateur community in Southeastern Pennsylvania's northern Bucks and southern Lehigh counties. That repeater group ceased operation in June of 2020 and returned to the air serving Southern California's central Orange County coast in October of 2023.
The WA3KEY UHF repeater operates on the standard frequency pair of 448.720 MHz TX and 443.720 MHz RX with a 114.8 Hz (Code 2B) CTCSS tone activated squelch from a location high above Newport's Back Bay in the Westcliff neighborhood. All users are welcome.
