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.

3.4 GHz (9cm)

UK Usage

IARU Recommendation

3,400.000-3,402.000 MHz

3,400.100 MHz                      Centre of activity

Narrow band

3,400.800-3,401.000 MHz   Propagation Beacons only

CW/EME/SSB

3,401.000-3,402.000 MHz   Remote control

3,402.000-3,456.000

All modes

3,456.000-3,458.000

3,456.000 MHz                       EME to USA

Narrow band

CW/EME/SSB

3,458.000-3,475.000

All modes

LICENCE NOTES:   Amateur Service: Secondary User.

Unattended operation is permitted for remote control, digital modes and beacons, except in the sub-bands

3,420-3,430 MHz  and 3,450-3,455 MHz within 50 km of  SO916223 (Cheltenham), SS206127 (Bude) and

SE202577 (Harrogate).

ISM = Industrial, scientific and medical

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.
