3-centimeter band
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]
List of notable frequencies
- 10.368.1 GHz Region 2 narrow band calling frequency[2][3]
- 10.368.2 GHz Region 1 narrow band calling frequency[4]
- 10.368.3 to 10.368.4 GHz Region 2 propagation beacons[2][3]
- 10.368.75 to 10.368.99 GHz Region 1 propagation beacons[4]
Wideband FM Channels
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 frequency pair for gunnplexers in North America. (10.200 to 10.300 GHz is reserved for gunnplexers in the ARRL Band Plan.[3])
‡ Should only be used if interference is not caused to narrow-band stations.
