| RSGB Band Plan (effective from 1st January 2016) | ||||
| 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. | ||||
| 1.8 MHz (160m) | Necessary | UK Usage | ||
| Bandwidth | ||||
| 1,810-1,838 kHz | 200 Hz | Telegraphy | ||
| 1,838-1,840 | 500 Hz | Narrow band modes | ||
| 1,840-1,843 | 2.7 kHz | All modes | ||
| 1,843-2,000 | 2.7 kHz | Telephony (Note 1), Telegraphy | ||
| 1,836 kHz QRP (low power) Centre of Activity, | ||||
| 1,960 kHz DF Contest beacons (14dBW) | ||||
| Note 1: Lowest LSB carrier frequency (dial setting) should be 1,843 kHz. | ||||
| AX25 packet should not be used on the 1.8 MHz band. | ||||
| LICENCE NOTES: 1,810-1,850 kHz Primary User: 1810-1830 kHz on a non-interference basis to stations outside of the UK. | ||||
| 1,850-2,000 kHz Secondary User: 32W (15dBW) Maximum | ||||
| 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. | ||||
