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. |

|
|
|
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, 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: 10,450-10,500 MHz - Secondary User. |
|
|
Unattended
operation is permitted for 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 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. |
