| RSGB Band Plan (effective from 1st January 2015) | ||||
| 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. | ||||
| 3.4 GHz (9cm) | Necessary | UK Usage | ||
| IARU Recommendation | Bandwidth | |||
| 3,400.000-3,401.000 MHz | 2.7 kHz | Narrowband Modes (including CW SSB, MGM, EME) | ||
| 3,400.100 MHz Centre of activity (Note 1) | ||||
| 3,400.750-3,400.800 MHz Local Beacons, 10W erp max | ||||
| 3,400.800-3,400.995 | 3,400.800-3,400.995 MHz Propagation Beacons only | |||
| Propagation Beacons | ||||
| 3,400.000-3,401.000 MHz | 200 kHz | 3,401.000-3,402.000 MHz Data, Remote control | ||
| 3,402.000-3,410.000 | Wideband Modes, including DATV Repeater Outputs | |||
| All modes (Notes 2, 3) | ||||
| Note 1: EME has migrated from 3456 MHz to 3400 MHz to promote harmonised usage and activity | ||||
| Note 2: Stations in many European countries have access to 3400-3410 MHz as permitted by ECA Table Footnote EU17 | ||||
| Note 3: Amateur Satellite downlinks planned | ||||
| LICENCE NOTES: Amateur Service - Secondary User - Subject to specific conditions and guidance | ||||
| 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. | ||||
| Foundation and Intermediate Licence holders are advised to check their licences for the permitted power limits and | ||||
| conditions applicable to their class of licence. | ||||
