RSGB Bandplan (effective from 1st December 2006)
The following bandplan is largely based on that agreed at the 2005 IARU Region 1 Conference with some local differences on
frequencies above 430 MHz.
10 GHz (3cm)                                                                           UK Usage  
IARU Recommendation    
10,000.000-10,125.000 MHz 10,002.5-10,027.5 MHz   Wideband transponders - 015 OUT
  10,027.5-10,052.5 MHz   Wideband transponders - 040 OUT
Digital modes 10,052.5-10,077.5 MHz   Wideband transponders - 065 OUT
  10,080-10,090 MHz          Packet links    
  10,090-10,110 MHz          Wideband beacons and operating (Note 1)
  10,110-10,120 MHz          Voice repeaters OUT
10,225.000-10,250.000 10,227.5-10,252.5 MHz   Wideband transponders - 425 OUT
All modes 10,252.5-10,227.5 MHz   Wideband simplex
10,250.000-10,350.000 10,277.5-10,302.5 MHz   Wideband transponders - 015 IN
Digital modes 10,302.5-10,327.5 MHz   Wideband transponders - 040 IN
10,350.000-10,368.000 10,327.5-10,352.5 MHz   Wideband transponders - 065 IN
All modes 10,352.5-10,368 MHz       Wideband modes
10,368.000-10,370.000 10,368-10,370 MHz          Narrowband modes (Note 3)       
Narrowband telegraphy 10,368.1 MHz                     Centre of activity
EME/SSB 10,368.8-10,369 MHz       Propagation Beacons only
Beacons    
10,370.000-10,450.000 10,370-10,390MHz         Wideband modes (Note 2)
  10,390-10,410 MHz         Wideband beacons and operating (Note 1)
All modes 10,412.5-10,437.5 MHz   Wideband transponders - 425 IN
  10,440-10,450 MHz         Voice repeaters RX
10,450.000-10,475.000 10,400-10,475 MHz         Unattended operation
  10,450-10,452 MHz         Alternative narrowband CW/EME/SSB (Note 3)
10,475.000-10,500.000    
All modes and Amateur satellite service ONLY
     satellites.    
     
Note 1.   10,400 MHz is the preferred frequency for wideband beacons but 10,100 MHz is still used.
Note 2.   Wideband FM is preferred between 10,350-10,400 MHz to encourage compatibility between narrowband systems, however
there is still activity between 10,050-10,125 MHz.
Note 3.   The current NB sub-band is at 10,368 MHz; however, a sub-band at 10,450 MHz is being considered as a possible future
alternative.  
Note 4.   Simplex TV operations should take place on wideband transponder inputs which are not being used by local transponders.
Note 5.   Wideband transponder pairs are designated by input/output frequencies.   The pairings shown are recommended but
occasionally variants may be needed to suit local circumstances.
Note 6.   10,475-10,500 MHz is allocated ONLY to the amateur satellite service and NOT to the amateur service.
LICENCE NOTES:   Amateur service: Secondary User: Amateur Satellite service:
                                  Amateur Satellite service: 10,450-10,500 MHz, Secondary User: Unattended operation is permitted for remote
                                  remote control,  digital modes and beacons, except in the sub-bands 10,000-10,125 MHz within 50 km of
                                  SO916223 (Cheltenham), SS206127 (Bude), SK985640 (Waddington) and SE202577 (Harrogate).
     
Notes to the Bandplan
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.
