The introduction of the new UK Amateur Licence in December 2006 overlapped other changes that were being agreed in the mm-Wave section of the frequency schedules. These changes are now implemented in the WT 2006 Act version of the new licence, issued on 8-Feb-2007.
Explanatory Notes
EU35 arose in CEPT after it was shown that QRM from new 79GHz UWB automotive short range radar (77-81GHz) would not be compatible
with the Amateur 77.5-78.0 GHz Primary allocation. As a consequence CEPT Footnote EU35 permits
the amateur services to remain in 75.5-76 GHz band on a Primary basis after 2006.
Subsequent to EU35, the bands 71-76 and 81-86 GHz were later designated by CEPT for light licensed short range high bandwidth links. Within these the 75.875-76 segment is a 125 MHz-wide guard band. Submissions to Ofcom highlighted this and the willingness to forgo 81-81.5GHz. Ofcom has used this segment to resolve the sharing situation. The continued use of 75.976 GHz by amateurs permits optimum separation from both datalinks and car radar, including the more common 76-77 GHz Cruise Control Long Range Radars.
The resultant solution reflects the culmination of submissions to Ofcom on car radar and CEPT. It is also in line with IARU-R1 2005 Davos Recommendation DV05_C5_Rec_08
