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.

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.
