RSGB Band Plan (effective from 1st January 2009)
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.
24 GHz (12mm)                                                                             UK Usage
IARU Recommendation    
24,000.000-24,050.000 MHz    
Satellites 24,025 MHz  Preferred operating frequency wideband equipment
  24,048.2 MHz                  Narrow band center of activity 
  24,048.750-24,048.800 MHz    Local Beacons, 10W erp max  
24,048.800-24,048.995 24,048.800-24,048.995 MHz    Propagation Beacons Only
Propagation Beacons  
All modes    
LICENCE NOTES:   Amateur Service: 24,000-24,050 MHz - Primary User: Users must accept interference from ISM users.
                                                                  24,050-24,150 MHz - Secondary User: May only be used with the written permission of Ofcom.   
                                                                  Users must accept interference from ISM users. 
                                                                  24,150-24,250 MHz - Secondary User: Users must accept interference from ISM users.
                                  Amateur Satellite Service: 24,000-24,050 MHz - Primary User: Users must accept intereference from ISM users.
                                  Unattended operation is permitted for remote control, digital modes and beacons, except 
                                   in the sub-bands 24,000-24,050 MHz within 50 km of SK985640 (Waddington) and 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.
