RSGB Band Plan (effective from 1st January 2012) | ||||
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. | ||||
7 MHz (40m) | Necessary | UK Usage | ||
Bandwidth | ||||
7,000-7,040 kHz | 200 Hz | Telegraphy. 7,030 kHz - QRP Centre of Activity | ||
7,040-7,047 | 500 Hz | Narrow band modes (Note 2) | ||
7,047-7,050 | 500 Hz | Narrow band modes, automatically controlled data stations (unattended) | ||
7,050-7,053 | 2.7 kHz | All modes, automatically controlled data stations (unattended), (Note 1) | ||
7,053-7,060 | 2.7 kHz | All modes, digimodes | ||
7,060-7,100 | 2.7 kHz | All modes, SSB Contest Preferred Segment digital voice 7,070kHz; SSB QRP Centre of Activity 7,090 kHz |
||
7,100-7,130 | 2.7 kHz | All modes, 7,110kHz - Region 1 Emergency Centre of Activiity. | ||
7,130-7,200 | 2.7 kHz | All modes, SSB Contest Preferred Segment; 7,165kHz - Image Centre of Activity | ||
7,175-7,200 | 2.7 kHz | All modes, priority for intercontinental operation | ||
Note 1: Lowest LSB carrier frequency (dial setting) should be 7,053 kHz. | ||||
Note 2: PSK31 activity starts from 7,040kHz. | ||||
Since 2009, the narrow band modes segment starts at 7,040kHz. | ||||

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. | ||||
