RSGB Usage Plan (effective from 1st January 2018)
Access to this band is available to Full Licensees only
See Licence Schedule notes for specific conditions
5 MHz (60m) Available UK Usage
  Width  
5258.5 - 5264.0 kHz 5.5 kHz       5262 kHz - CW QRP Centre of Activity
5276.0 - 5284.0 8 kHz       5278.5 kHz - may be used for UK emergency comms traffic
5288.5 - 5292.0 3.5 kHz       Beacons on 5290 kHz (Note-2)
5298.0 - 5307.0 9 kHz  
5313.0 - 5323.0 10 kHz       5317 kHz - AM 6kHz max. bandwidth
5333.0 - 5338.0 5 kHz  
5354.0 - 5358.0 4 kHz      Within WRC-15 Band
5362.0 - 5374.5 12.5 kHz      Partly within WRC-15 band, WSPR
5378.0 - 5382.0 4 kHz  
5395.0 - 5401.5 6.5 kHz  
5403.5 - 5406.5 3 kHz  
Unless indicated, usage is all-modes (necessary bandwidth to be within channel limits)
Note 1: Upper Sideband is recommended for SSB activity. 
Note 2: Activity should avoid interference to the experimental beacons on 5290 kHz
Note 3: Amplitude Modulation is permitted with a maximum bandwidth of 6kHz, on frequencies with at least 6kHz available width
Note 4: Contacts within the UK should avoid the WRC-15 band (5351.5 - 5366.5 kHz) if possible

Notes to the Usage 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.
