Note 1:  Non-Santa Clara County agencies are encouraged to use their own BBS(s) in their area. This reduces the chance of "hidden transmitter problems" and regular use, such as weekly check-ins, helps test inter-county communications.  The Packet Network Addressing page contains full details of how to address messages to/from BBSs outside of Santa Clara County.  In the event an agency doesn't have their own BBS or the network links have failed, the Santa Clara County BBSs listed here are recommended for each agency.

For complete message addressing information, see:  Packet Network Addressing.
