| 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. | ||||
| 134 GHz (2mm) | UK Usage | |||
| IARU Recommendation | ||||
| 134,000-134,928 MHz | ||||
| All modes | ||||
| 134,928 -134,930 | IARU Region-1 preferred centre of activity | |||
| Narrowband modes | ||||
| 134,928.800 - 134,928.990 Propagation Beacons Only | ||||
| 134,930 -136,000 | ||||
| All modes | ||||
| LICENCE NOTES: | ||||
| 134,000-136,000 MHz Amateur Service and Amateur Satellite Service - Primary User. | ||||
| Unattended operation is permitted for remote control, digital modes and beacons, except within 50 km of | ||||
| SK985640 (Waddington) and SE202577 (Harrogate). | ||||
| The following bands are also allocated to the Amateur Service and the Amateur Satellite Service:- | ||||
| 122,250-123,000 MHz Amateur Service only, Secondary User | ||||
| 136,000-141,000 MHz Secondary User | ||||
| 241,000-248,000 MHz Secondary User | ||||
| 248,000-250,000 MHz Primary User | ||||
| 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. | ||||
