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. 14MHz (20m) Necessary UK Usage Bandwidth 14,000-14,060 kHz 200 Hz Telegraphy - contest preferred 14,055 kHz QRS (slow telegraphy Centre of Activity 14,060-14,070 200 Hz Telegraphy 14,060 kHz QRP (low power) Centre of Activity 14,070-14,089 500 Hz Narrow band modes 14,089-14,099 500 Hz Narrow band modes - automatically controlled data stations (unattended) 14,099-14,101 IBP - reserved exclusively for beacons 14,101-14,112 2.7 kHz All modes - automatically controlled data stations (unattended) 14,112-14,125 2.7 kHz All modes (excluding digimodes) 14,125-14,300 2.7 kHz All modes - SSB contest preferred segment 14,130kHz - digital voice centre of activity 14,195+- 5 kHz Priority for Dxpeditions 14,230 kHz - Image Centre of Activity. 14,285 kHz - QRP Centre of Activity 14,300-14,350 2.7 kHz All modes 14,300 kHz Global Emergency Centre of Activity LICENCE NOTES: Amateur Service - Primary User. 14,000-14,250 kHz 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 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.
