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 GHz and 3.500 GHz, and it is available only on a secondary basis. The amateur satellite band is between 3.400 GHz and 3.410 GHz, 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 and Israel, the band 3.400–3.475 GHz is also allocated to the amateur service on a secondary basis (ITU footnote 5.431). In CEPT's "European Common Allocation Table", footnote EU17 allocates 3.40 GHz to 3.41 GHz to European amateurs on a secondary basis. In the US, the FCC is recommending removing the amateur service from this band in order to make room for the 5G cellular system. There have been many objections to this proposal by Amateur Radio operators, including the ARRL. Under an October 2020 decision, it remains available on a secondary basis to those who have acquired the license before October 2020.
