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. 241 GHz (1.2mm) UK Usage IARU Recommendation 241,000-248,000 MHz All modes 241,600 MHz +/-IF - UK centre of activity 248,000-248.001 MHz IARU Region-1 preferred centre of activity Narrowband modes 248,001-250,000 MHz 248,800 MHz +/-IF - UK centre of activity All modes LICENCE NOTES: 241,000-248,000 MHz Amateur Service and Amateur Satellite Service - Secondary User. 248,000-250,000 MHz Amateur Service and Amateur Satellite Service - Primary User. Note specific conditions apply within 50 km of SK985640 (Waddington) and SE202577 (Harrogate). 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 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.
