| 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. | ||||||
| 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 | ||||||
| 24,048.750-24,048.800 MHz Local Beacons, 10W erp max | ||||||
| 24,048.800-24,048.995 | 24,048.800-24,048.995 MHz Propagation Beacons Only | |||||
| Propagation Beacons | ||||||
| 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 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. | ||||||
