The 9-centimeter band is a portion of the SHF (microwave) radio spectrum internationally allocated to amateur radio and amateur satellite use. The amateur radio band, in ITU regions 1 and 2, is between 3,300 MHz and 3,500 MHz, and it is available only on a secondary basis. The amateur satellite band is between 3,400 MHz and 3,410 MHz, and it is only available in ITU Regions 1 and 2, on a non-interference basis to other users (ITU footnote 5.282). In Germany, Israel and the United Kingdom, the band 3,400 - 3,475 MHz is also allocated to the amateur service on a secondary basis (ITU footnote 5.431).[1]

In CEPT's "European Common Allocation Table", footnote EU17 allocates 3,400 MHz to 3,410 MHz to European amateurs on a secondary basis.[2]


Frequencies of note[edit]

  • 3,400.1 MHz IARU Region-1 Calling frequency and Global EME centre of activity[3]
  • 3,456.1 MHz IARU Region 2 Legacy Calling Frequency

EU17: In the sub-bands 3400-3410 MHz, 5660-5670 MHz, 10.36-10.37 GHz and 10.45-10.46 GHz the amateur service operates on a secondary basis. In making assignments to other services, CEPT administrations are requested wherever possible to maintain these sub-bands in such a way as to facilitate the reception of amateur emissions with minimal power flux densities.
