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. 122 GHz (2.5mm) UK Usage IARU Recommendation 122,250-122.251 MHz IARU Region-1 preferred centre of activity Narrowband modes 122,251-123,000 MHz 122,256 / 122,400 MHz - UK centre of activity All modes LICENCE NOTES: 122,250-123,000 MHz Amateur Service only - 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.
