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.

24 GHz (12mm)

UK Usage

IARU Recommendation

24,000.000-24,050.000 MHz

Satellites

24,025 MHz  Preferred operating frequency wideband equipment

24,048.2 MHz                  Narrow band center of activity

24,048.8-24,049 MHz    Propagation Beacons Only

24,050.000-24,250.000

All modes

LICENCE NOTES:   Amateur service: 24,000-24,050 MHz, Primary user: Users must accept interference from ISM users.

24,050-24,150 MHz: Secondary user: May only be used with the written permission of Ofcom.

Users must accept interference from ISM users.

24,150-24,250 MHz: Secondary user: Users must accept interference from ISM users.

Amateur satellite service: 24,000-24,050 MHz: Primary user: Users must accept intereference from ISM users.

Unattended operation is permitted for remote control, digital modes and beacons, except

in the sub-bands 24,000-24,050 MHz within 50 km of SK985640 (Waddington) 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.
