RSGB Band Plan (effective from 1st January 2012)
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.
134 GHz (2mm)                                                                             UK Usage
IARU Recommendation    
134,000-134,928 MHz    
All modes    
   
134,928 -134,930 IARU Region-1 preferred centre of  activity
Narrowband modes    
  134,928.800 - 134,928.990 Propagation Beacons Only
     
134,930 -136,000    
All modes    
     
LICENCE NOTES:  
134,000-136,000 MHz   Amateur Service and Amateur Satellite Service - Primary User.  
                                          Unattended operation is permitted for remote control, digital modes and beacons, except within 50 km of
                                          SK985640 (Waddington) and SE202577 (Harrogate).
     
The following bands are also allocated to the Amateur Service and the Amateur Satellite Service:-
122,250-123,000 MHz   Amateur Service only, Secondary User 
136,000-141,000 MHz   Secondary User
241,000-248,000 MHz   Secondary User
248,000-250,000 MHz   Primary User  
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.
