RSGB Band Plan January 2022

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.
