Note

In the event of repeater failure during an exercise or emergency, the SMRA asks that everyone use the following frequencies, in this order:

  • 146.460 FM repeater, plus 1,000 kHz offset, tone 67.0 Hz
  • 145.430 FM repeater, plus 600 kHz offset, no tone
  • 146.460 FM simplex (depending on your transceiver, you may be able to just turn off duplex on the memory channel programmed for this repeater)
  • 144.160 USB (meet dx stations beyond FM range here and coordinate a SSB frequency to use)
