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
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.
