RSGB Band Plan (effective from 1st June 2016)
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.
3.5 MHz (80m) Necessary UK Usage
3,500-3,510 kHz 200 Hz Telegraphy - Priority for inter-continental operation
3,510-3,560 200 Hz Telegraphy - contest preferred. 3,555 kHz - QRS (slow telegraphy) Centre of Activity
3,560-3,570 200 Hz Telegraphy 3,560 kHz - QRP (low power) Centre of Activity
3,570-3,580 200 Hz Narrow band modes
3,580-3,590 500 Hz Narrow band modes
3,590-3,600 500 Hz Narrow band modes - automatically controlled data stations (unattended)
3,600-3,620 2.7 kHz All modes - automatically controlled data stations (unattended), (Note 1)
3,600-3,650 2.7 kHz All modes - Phone contest preferred, (Note 1). 3,630kHz - digital voice Center of Activity
3,650-3,700 2.7 kHz All modes - Telephony, Telegraphy
    3,663 kHz may be used for UK emergency comms traffic.
    3,690 kHz SSB QRP (low power) Centre of Activity.
3,700-3,775 2.7 kHz All modes - Phone contest preferred
    3,735 kHz Image mode Centre of Activity
    3,760 kHz IARU Region 1 Emergency Centre of Activity
3,775-3,800 2.7 kHz All modes - Phone contest preferred
    Priority for inter-continental telephony (SSB) operation
Note 1: Lowest LSB carrier frequency (dial setting) should be 3,603 kHz.

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.
