RSGB Band Plan January 2024

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 Bandwidth 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.
