RSGB Band Plan January 2022

RSGB Band Plan (effective from 1st January 2020) The following band plan is largely based on that agreed at IARU Region 1 General Conferences with some local differences on on frequencies above 430 MHz. 134 GHz (2mm) UK Usage IARU Recommendation 134,000-134,928 MHz All modes 134,928 -134,930 IARU Region-1 preferred centre of activity Narrowband modes 134,928.800 - 134,928.990 Propagation Beacons Only 134,930 -136,000 All modes LICENCE NOTES: 134,000-136,000 MHz Amateur Service and Amateur Satellite Service - Primary User. Unattended operation is permitted for remote control, digital modes and beacons, except within 50 km of SK985640 (Waddington) and SE202577 (Harrogate). The following bands are also allocated to the Amateur Service and the Amateur Satellite Service:- 122,250-123,000 MHz Amateur Service only, Secondary User 136,000-141,000 MHz Secondary User 241,000-248,000 MHz Secondary User 248,000-250,000 MHz Primary User Notes to the Band Plan Note-1: Access to frequencies >275 GHz by Full Licensees is also possible by NoV ITU-R Recommendation SM.328 (extract) Necessary bandwidth : For a given class of emission, the width of the frequency band which is just sufficient to ensure the transmission of information at the rate and with the quality required under specified conditions. The use of Amplitude Modulation (AM) is acceptable in the all modes segments but users are asked to consider adjacent channel activity when selecting operating frequencies.
