Unless otherwise noted, repeater usage for digital communications is at the discretion of the respective repeater trustee.

There may be digital users operating on frequencies other than the above. However, only those frequencies above have been coordinated via the SCDCC by the frequency coordinators.

Any other usage is either uncoordinated or was coordinated directly by the frequency coordinators to a specific trustee or group (Treat as if the coordination was to a "closed" or "private" repeater).

The following repeaters are noted as designated for disaster relief purposes only (including drills). Before using for other purposes, one should check with the coordinee.

Frequency Emission Speed - Restricted Use Repeaters:

1299.600 X 25K0 F2D 9600 Baud - Coordinated to LA County DCS - Note that
1299.800 X 25K0 F2D 9600 Baud - Coordinated to LA County DCS - these have
1299.900 X 25K0 F2D 9600 Baud - Coordinated to LA County DCS - an "odd"
1299.950 X 25K0 F2D 9600 Baud - Coordinated to LA County DCS - split.
