The 3 centimeter or 10 GHz band is a portion of the SHF (microwave) radio spectrum internationally allocated to amateur radio and amateur satellite use on a secondary basis. The amateur radio band is between 10.00 GHz and 10.50 GHz, and the amateur satellite band is between 10.45 GHz and 10.50 GHz. The allocations are the same in all three ITU regions.[1]

Frequencies of note[edit]

  • 10.364 GHz Calling frequency
  • 10.368 GHz Narrow band calling frequency
  • 10.368.3 to 10.368.4 GHz Propagation beacons

Wideband FM Channels[edit]

Common Wideband FM frequencies used with gunnplexers. Operation is in full-duplex with a 30 or 90 MHz split:

  • 10.220 GHz
  • 10.250 GHz †
  • 10.280 GHz †
  • 10.310 GHz
  • 10.340 GHz
  • 10.370 GHz ‡
  • 10.400 GHz
  • 10.430 GHz

† Most commonly used pair for gunnplexers in North America.

‡ Should only be used if interference is not caused to narrow-band stations.
