MNRC telemetry

The McLaughlin Mine property in Lake and Yolo counties is on property owned and formerly operated by Homestake Mining Company as a surface gold mine. The site is now managed as a UC Davis reserve.

Due to the remoteness of the site, digital telephone data circuits are not available. During 2003-2004, BSL engineers permitted, designed, prefabricated and installed a two-hop wireless radio bridge to a State of California radio and microwave facility at Mt Saint Helena, twenty five kilometers away. From the Mt Saint Helena site, data are relayed to the California Department of Forestry and Fire Protection (CDF) command center in the Napa Valley. At that point, a frame-relay circuit provides communications to UC Berkeley.

During early 2005, the State of California began installation of upgrades to the radio facilities atop Mt Saint Helena site. These upgrades are to include a new antenna tower. The State of California requested that BSL relocate and remount our directional antennas at Mt Saint Helena site. Concurrent with remounting the antennas, BSL engineers installed battery back-up for the radio system.
