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. BLURA ceased operation in June of 2020 and returned to the air serving Southern California's central Orange County coast in October of 2023.

Analog FM is with 114.8 Hz (Code 2B) CTCSS tone activated squelch and DMR is with Color Code 1 and Time Slot 1 on Talk Group 2 (local) from a location high above Newport's Back Bay in the Westcliff neighborhood. All users are welcome.
