RSGB Band Plan January 2024

RSGB Band Plan (effective from 1st January 2021) 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. 21 MHz (15m) Neccesary UK Usage Bandwidth 21,000-21,070 kHz 200 Hz Telegraphy 21,055 kHz QRS (slow telegraphy) Centre of Activity. 21,060 kHz QRP (low power) Centre of Activity 21,070-21,090 500 Hz Narrow band modes 21,090-21,110 500 Hz Narrow band modes - automatically controlled data stations (unattended) 21,110-21,120 2.7 kHz All modes (excluding SSB) - automatically controlled data stations (unattended) 21,120-21,149 500 Hz Narrow band modes 21,149-21,151 IBP - reserved exclusively for beacons 21,151-21,450 2.7 kHz All modes. 21,180kHz - digital voice centre of activity 21,285 kHz - QRP Centre of Activity. 21,340 kHz - Image Centre of Activity. 21,360 kHz - Global Emergency Centre of Activity Note 1: 21,125-21,245 is also designated for use by amateur satellites LICENCE NOTES: Amateur and Amateur Satellite Service - Primary User . 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 t 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.
