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. 28 MHz (10m) Necessary UK Usage Bandwidth 28,000-28,070 kHz 200 Hz Telegraphy 28,055 kHz QRS (slow telegraphy) Centre of Activity. 28,060 kHz QRP (low power) Centre of Activity. 28,070-28,120 500 Hz Narrow band modes 28,120-28,150 500 Hz Narrow band modes - automatically controlled data stations (unattended) 28,150-28,190 500 Hz Narrow band modes 28,190-28,199 IBP - regional time shared beacons 28,199-28,201 IBP - world wide time shared beacons 28,201-28,225 IBP - continuous-duty beacons 28,225-28,300 2.7 kHz All modes - beacons 28,300-28,320 2.7 kHz All modes - automatically controlled data stations (unattended) 28,320-29,000 2.7 kHz All modes 28,330 kHz - Digital Voice centre of activity 28,360 kHz - QRP Centre of Activity. 28,680 kHz - Image Centre of Activity. 29,000-29,100 - All modes - See Note-1 regarding 29,000-29,510 kHz 29,100-29,200 - All modes - FM simplex - 10 kHz channels 29,200-29,300 - All modes - automatically controlled data stations (unattended) 29,270 kHz UK Internet voice gateway - unattended 29,280 kHz UK Internet voice gateway - unattended 29,290 kHz UK Internet voice gateway - unattended 29,300-29,510 - Satellite links 29,510-29,520 Guard channel 29,520-29,590 6 kHz All modes - FM repeater inputs (RH1-RH8) 29,600 6 kHz All modes - FM calling channel 29,610 6 kHz All modes - FM simplex repeater (parrot) - input and output 29,620-29,700 6 kHz All modes - FM repeater outputs (RH1-RH8) Note-1: Experimental wide bandwidth operation within 29,000 - 29510 must be on a non-interference basis to other stations, including the amateur satellite service segment at 29300 - 29510 kHz. LICENCE NOTES: Amateur and Amateur Satellite Service - Primary User: 26dBW permitted Beacons may be established for D.F. competitions except within 50km of NGR SK985640 (Waddington) 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.
