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 MHz (30m) Neccesary UK Usage
  Bandwidth  
10,100-10,140 kHz 200 Hz Telegraphy (CW)
    10,116 kHz - QRP (low power) Centre of Activity
10.140-10.150 500 Hz Narrow band modes
    Automatically controlled data stations (unattended) should avoid the use of the 10 MHz band
     
The 10 MHz band is allocated to the Amateur Service only on a Secondary basis.  The IARU has agreed that only CW and other 
narrow bandwidth modes are to be used on this band.   Likewise the band is not to be used for contests and bulletins.
SSB may be used on the 10 MHz band during emergencies involving the immediate safety of life and property, and only by stations
actually involved with the handling of emergency traffic.   The band segment 10,120-10,140 kHz may only be used for SSB  
transmissions in the area of Africa south of the equator during local daylight hours.
LICENCE NOTES: Amateur Service - Secondary User.
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.
