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.
2.3 GHz (13cm) Necessary  UK Usage  
IARU Recommendation Bandwidth    
2,310.000-2,320.000 MHz      
Sub-regional 200 kHz 2,310.000-2,310.500 MHz   Repeater links  
(National band plans)      
    2,311.000-2,315.000 MHz   High speed data  
2,320.000-2,320.800 2.7 kHz Preferred Narrowband Segment  
    2,320.000-2,320.025 MHz   Moonbounce  
    2,320.200 MHz                      SSB centre of activity  
    2,320.750-2,320.800 MHz   Local Beacons, 10W erp max
2,320.800-2,321.000   2,320.800-2,320.990 MHz   Propagation Beacons only
Beacons exclusive    
2,321.000-2,322.000 20 kHz FM/DV    - see also Note 1
2,322.000-2,350.000   Wideband Modes, including data, ATV 
2,390.000-2,400.000   All modes
2,400.000-2,450.000   2,435.000 MHz                      ATV repeater outputs
Satellites   2,440.000 MHz                      ATV repeater outputs
Note 1:   Stations in countries which do not have access to the all modes section 2,322-2,400 MHz, may use the 
segment 2,321-2,322 MHz for data transmission.
Note 2:   Stations in countries that do not have access to the narrow band segment 2,320-2,322 MHz, use the alternative narrow 
band segments 2,304-2,306 MHz, 2,308-2,310 MHz and 2400-2402 MHz
Note 3:  The segment 2,433-2,443 MHz may be used for ATV if no satellite is using the segment.
LICENCE NOTES:   Amateur Service - Secondary User: Users must accept interference from ISM users. 
                                  Amateur Satellite Service: 2,400-2,450 MHz - Secondary User:   Users must accept interference from ISM users
 Operation in 2310-2350 and 2390-2400 MHz are subject to specific conditions and guidance
                                 In the sub-bands 2,310.000-2,310.4125 and 2,392-2,450 MHz 
                                  unattended operation is not allowed within 50km of SS206127 (Bude) or SE202577 (Harrogate).
                                  ISM = Industrial, scientific and medical.
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.
