| 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 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. | ||||
