| RSGB Band Plan (effective from 1st January 2009) | ||||
| 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. | ||||
| 24 MHz (12m) | Necessary | UK Usage | ||
| Bandwidth | ||||
| 24,890-24,915 kHz | 200 Hz | Telegraphy | ||
| 24,906 kHz QRP (low power) centre of activity | ||||
| 24,915-24,925 | 500 Hz | Narrow band modes | ||
| 24,925-24,929 | 500 Hz | Narrow band modes - automatically controlled data stations (unattended) | ||
| 24.929-24.931 | IBP - reserved exclusively for beacons | |||
| 24,931-24,940 | 2700 | All modes - automatically controlled data stations (unattended) | ||
| 24,940-24,990 | 2700 | All modes, 24,950kHz SSB QRP Centre of Activity | ||
| 24,960kHz digital voice centre of activity | ||||
| LICENCE NOTES: Amateur and Amateur Satellite Service - Primary User. | ||||
| The band is not to be used for contests or bulletins. | ||||
| 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. | ||||
