The Bay-Net system is sponsored by the Northern California Cactus Radio Association (NCCRA) and Sierra Radio Systems. In 2005, the board of NCCRA voted to take two of the Cactus UHF repeater’s in the bay area, link them together and create an open repeater system covering the San Francisco bay area including San Jose, Oakland, Berkeley and the surrounding areas. The system is used by the American Red Cross, ARES and other public service organizations for events and emergency communications. All radio amateurs are welcome to use the system. Sierra Radio Systems donated the control systems, radio and computer equipment to build out the system.
