SANDRA sponsors Nets on Sunday and Wednesday nights.  Our Nets are open to members and non-members alike.  You are welcome to list for sale or wanted items on SANDRA nets as long as they are ham radio related.  Amateur Radio Newsline is featured after roll call on the Sunday night Net.

When SANDRA Nets are held, the 2m, 220 and 440 repeaters on each hilltop are linked together.  You can check-in from any one of the three repeaters on Otay or Laguna.  The repeaters are only linked during Nets and in emergency situations.  Normal status for the repeaters is for them to operate independently of each other.

Many local clubs and organizations use SANDRA repeaters for nets, drills and other activities.  SANDRA supports equal access on a non-exclusive basis to its repeaters for all local clubs and groups who first request to use SANDRA repeaters for their activities.

SANDRA has a responsibility to maintain a list of all groups that use SANDRA repeaters for formal activities, including the days, times and duration of scheduled use.  This helps ensure there are no scheduling conflicts between two or more groups. It also helps ensure that our repeaters are continually accessible by our members, since no single group is permitted to have exclusive use of any repeater at any time.


In actual emergency situations, SANDRA defers to FCC part 97.101, subparagraph (c):

97.101 General standards.

(c) At all times and on all frequencies, each control operator must give priority to stations providing emergency communications, except to stations transmitting communications for training drills and tests in RACES

Please note also that ARES will be given priority but not sole use of the repeaters during actual emergency conditions.

For more information about SANDRA policy related to repeater use, nets and operations, please refer to the SANDRA club operating policy manual, Section 1, Paragraphs 2 and 3
