| RSGB Band Plan (effective from 1st January 2015) | ||||
| 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. | ||||
| 2.3 GHz (13cm) | Necessary | UK Usage | ||
| IARU Recommendation | Bandwidth | |||
| 2,310.000-2,320.000 MHz | ||||
| Sub-regional | 200 kHz | 2,310.000-2,310.500 MHz Repeater links | ||
| (National band plans) | ||||
| 2,311.000-2,315.000 MHz High speed data | ||||
| Preferred Narrowband Segment | ||||
| 2,320.000-2,320.150 | 500 Hz | 2,320.000-2,320.025 MHz Moonbounce | ||
| 2,320.150-2,320.800 | 2.7 kHz | 2,320.200 MHz SSB centre of activity | ||
| 2,320.750-2,320.800 MHz Local Beacons, 10W erp max | ||||
| 2,320.800-2,321.000 | 2,320.800-2,320.990 MHz Propagation Beacons only | |||
| Beacons exclusive | ||||
| 2,321.000-2,322.000 | 20 kHz | FM/DV - see also Note 1 | ||
| 2,322.000-2,350.000 | Wideband Modes, including data, ATV | |||
| 2,390.000-2,400.000 | All modes | |||
| 2,400.000-2,450.000 | 2,435.000 MHz ATV repeater outputs | |||
| Satellites | 2,440.000 MHz ATV repeater outputs | |||
| Note 1: Stations in countries which do not have access to the all modes section 2,322-2,400 MHz, may use the | ||||
| segment 2,321-2,322 MHz for data transmission. | ||||
| Note 2: Stations in countries that do not have access to the narrow band segment 2,320-2,322 MHz, use the alternative narrow | ||||
| band segments 2,304-2,306 MHz, 2,308-2,310 MHz and 2400-2402 MHz | ||||
| Note 3: The segment 2,433-2,443 MHz may be used for ATV if no satellite is using the segment. | ||||
| LICENCE NOTES: Amateur Service - Secondary User: Users must accept interference from ISM users. | ||||
| Amateur Satellite Service: 2,400-2,450 MHz - Secondary User: Users must accept interference from ISM users | ||||
| Operation in 2310-2350 and 2390-2400 MHz are subject to specific conditions and guidance | ||||
| In the sub-bands 2,310.000-2,310.4125 and 2,392-2,450 MHz | ||||
| unattended operation is not allowed within 50km of SS206127 (Bude) or 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. | ||||
