Plans

  • ** In flux **
  • Reposition W2GMD-SANBRUNO-RM5 to point at Daly City
  • Replace W2GMD-SANBRUNO-NSM5 with Rocket + Sector Antenna
  • Reposition and validate airFiber link to Fish Ranch.
    • Reconfigure networking
  • Make airFiber and EdgePoint available for management on AREDN LAN
    • Also on management VLAN and UISP
  • Add the LHG dish connecting to CCCC

Coordination

The San Bruno Mountain HAM site is own and managed by Matthew Kaufman as part of the WB6ECE Repeater Group. Coordination of changes to the site (e.g. new radios) is managed on the mailing list Sbruno_shack. Unfortunately this is an invite only group with no public archives.

Commercial Neighbors

The local WISP in this area is Etheric although they use a different tower. They license (WQTV709) spectrum from 11.2 GHz to 11.7 GHz.
