RSGB Band Plan (effective from 1st January 2018)
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
50.000-50.100 500 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

    50.110 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
50.500-52.000 12.5 kHz All Modes. 
    50.510 MHz SSTV (AFSK)
    50.520 MHz   Internet voice gateway (10 kHz channels), (IARU common channel)
    50.530 MHz   Internet voice gateway (10 kHz channels), (IARU common channel)
    50.540 MHz   Internet voice gateway (10 kHz channels), (IARU common channel)
    50.550 MHz   Image/Fax working frequency
    50.620-50.750 MHz   Digital communications
    50.630 MHz    Digital Voice (DV) calling
    50.710-50.890 MHz   FM/DV Repeater Outputs (10 kHz channel spacing) 
    51.210-51.390 MHz   FM/DV Repeater Inputs (10 KHz channel spacing) (Note 4)
    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)
    51.770 & 51.790 MHz   See Note 5
    51.810-51.990 MHz.  FM/DV Repeater Outputs  (IARU aligned channels)
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 by Aug-2014 
               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 5: May be used for Emergency Communications and Community Events
Note-6: Digital Experiments to support innovation may occur at 50.6, 51.0 or 51.7 MHz with a 100kHz maximum bandwidth 
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.
