| RSGB Band Plan (effective from 1st January 2012) | ||||
| 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. | ||||
| 76 GHz (4mm) | UK Usage | |||
| IARU Recommendation | ||||
| 75,500-76,000 MHz | ||||
| All modes (preferred) | 75,976.200 MHz IARU Region 1 preferred centre of activity | |||
| 76,000.000-77,500.000 | ||||
| All modes | ||||
| 77,500-78,000 | 77,500.200 MHz Alternative IARU recommended Narrowband segment | |||
| All modes (preferred) | ||||
| 78,000-81,000 | ||||
| All modes | ||||

| 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. | ||||
