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.
70 MHz (4m) Necessary  UK Usage (Note 1)
70.000-70.090 MHz 1 kHz Propagation Beacons only 
70.090-70.100 1 kHz Personal Beacons
70.100-70.250 2.7 kHz Narrow Band modes
    70.185 MHz    Cross-band activity centre
    70.200 MHz    CW/SSB centre
    70.250 MHz    MS centre
70.250-70.294 12 kHz All Modes 
    70.260 MHz    AM/FM calling
    70.270 MHz    MGM centre of activity
70.294-70.500 12 kHz All modes channelised operations using 12.5 kHz spacing.

Note 1: Usage by operators in other countries may be influenced by restrictions in their national allocations
Note 2: May be used for Emergency Communications and Community Events
LICENCE NOTES: Amateur Service 70.0-70.5 MHz   Secondary User: 160W (22dBW) Maximum
                                Available on the basis of non-interference to other services (inside or outside the UK). 
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.
