UK Band Plan 4m

4M / 70 Mhz
In the UK the 70MHz (4 Metre) band is allocated with Secondary status. It is available on the basis of non-interference to other services inside or outside of the UK. For Full Licensees the power limit is restricted to 160W (22dBW) – lower than normal.

RSGB Band Plan (effective from 1st January 2021)

Notes to the Band Plan
Note-1: Access to 70.5 – 71.5 MHz by Full Licensees is also possible by NoV 
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.
