RSGB Band Plan January 2024

RSGB Band Plan (effective from 1st January 2024) 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 134,256 / 134,400 MHz - UK centre of activity 134,928-134,930 IARU Region-1 preferred centre of activity Narrowband modes 134,930 -136,000 All modes 136,000 -141,000 All modes LICENCE NOTES: 134,000-136,000 MHz Amateur Service and Amateur Satellite Service - Primary User. 136,000-141,000 MHz Amateur Service and Amateur Satellite Service - Secondary User. Note specific conditions apply within 50 km of SK985640 (Waddington) and SE202577 (Harrogate). Notes to the Band Plan ITU-R Recommendation SM.328 (extract) Necessary bandwidth : For a given class of emission, the width of the frequency band which is just sufficient t 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.
