| 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 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. | ||||
