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.
50 MHz (6m) Necessary  UK Usage
50.000-50.100 MHz 500 Hz Telegraphy Only (except for Beacon Project) Note-2  
    50.000-50.030 MHz reserved for Synchronised Beacon Project (Note 2)  
    Region-1: 50.000-50.010;  Region-2: 50.010-50.020;  Region-3: 50.020-50.030   
    50.050 MHz   Future International Centre of Activity
    50.090 MHz   Intercontinental DX Centre of Activity (Note 1)
50.100-50.200 2.7 kHz SSB/Telegraphy - International Preferred
    50.100-50.130 MHz  Intercontinental DX Telegraphy & SSB (Note 1)
    50.110 MHz   Intercontinental DX Centre of Activity
    50.130-50.200 MHz  General International Telegraphy & SSB
    50.150 MHz   International Centre of Activity
50.200-50.300 2.7 kHz SSB/Telegraphy - General Usage
    50.285 MHz   Crossband Centre of Activity
50.300-50.400 2.7 kHz MGM/Narrowband/Telegraphy
    50.305 MHz   PSK Centre of Activity
    50.310-50.320 MHz   EME
    50.320-50.380 MHz   MS
50.400-50.500   Propagation Beacons Only
50.500-50.700 - All Modes. 
    50.520 MHz  FM/DV Internet voice gateway 
    50.530 MHz  FM/DV Internet voice gateway 
    50.540 MHz  FM/DV Internet voice gateway 
    50.600-50.700 MHz   Digital communications
    50.630 MHz    Digital Voice (DV) calling
50.700-50.900 12 kHz 50.710-50.890 MHz   FM/DV Repeater Outputs (10 kHz channel spacing) 
50.900-51.200 - All Modes
51.200-51.400 12 kHz 51.210-51.390 MHz   FM/DV Repeater Inputs (10 KHz channel spacing) (Note 4)
51.400-52.000 - All Modes
    51.410-51.590 MHz   FM/DV Simplex (Note 3) (Note 4)
    51.510 MHz  FM calling frequency
    51.530 MHz  GB2RS news broadcast and slow morse
    51.650 & 51.750 MHz   See Note 5 (25kHz aligned)
    51.970 & 51.990 MHz   See Note 5
Note 1: Only to be used between stations in different continents (not for intra-European QSOs). 
Note 2: 50.0-50.1MHz is currently shared with Propagation Beacons. These are due to be migrated 
              to 50.4-50.5 MHz, to create more space for Telegraphy and a new Synchronised Beacon Project
Note 3: 20 kHz channel spacing. Channel centre frequencies start at 51.430 MHz.
Note 4: Embedded data traffic is allowed with digital voice (DV)
Note 5: May be used for Emergency Communications and Community Events
Note-6: Digital Experiments to support innovation may occur around 50.6, 51.0 or 51.7 MHz  
              with maximum bandwidths of 50, 200 and 500 kHz respectively on a shared non-interference basis
LICENCE NOTES: Amateur Service 50.0-51.0 MHz - Primary User.
                                Amateur Service 51.0-52.0 MHz - Secondary User: 100W (20dBW) max 
                                Available on the basis on 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.
