| RSGB Bandplan (effective from 1st December 2006) | ||||
| The following bandplan is largely based on that agreed at the 2005 IARU Region 1 Conference with some local differences on | ||||
| frequencies above 430 MHz. | ||||
| 50 MHz (6m) | Necessary | UK Usage | ||
| Bandwidth | ||||
| 50.000-50.100 MHz | Telegraphy | |||
| 50.000-50.080 MHz Propagation Beacons only | ||||
| 500 Hz | 50.090 MHz Telegraphy - Centre of Activity | |||
| 50.100-50.500 | 2.7 kHz | All Narrow Band Modes. | ||
| 50.100-50.130 MHz Intercontinental telegraphy & SSB (Note 1) | ||||
| 50.110 MHz DX calling (Note 2). | ||||
| 50.150 MHz SSB Centre of Activity | ||||
| 50.185 MHz Crossband Centre of Activity | ||||
| 50.200 MHz MS Centre of Activity | ||||
| 50-210-50.250 MHz JT6M | ||||
| 50.230 MHz JT6M calling frequency | ||||
| 50.250 MHz PSK31 Centre of Activity | ||||
| 50.500-52.000 | 12.5 kHz | All Modes. | ||
| 50.510 MHz SSTV (AFSK) | ||||
| 50.520 MHz Internet voice gateway (10 kHz channels) | ||||
| 50.530 MHz Internet voice gateway (10 kHz channels) | ||||
| 50.540 MHz Internet voice gateway (10 kHz channels) | ||||
| 50.550 MHz Fax working frequency | ||||
| 50.600 MHz RTTY (FSK) | ||||
| 50.620-50.750 MHz Digital communications | ||||
| 50.710-50.910 MHz FM repeater outputs (10 kHz channel spacing) | ||||
| 51.210 MHz. Can be used by RAYNET | ||||
| 51.210-51.410 MHz FM repeater inputs (10 KHz channel spacing) | ||||
| 51.430-51.590 MHz FM (Note 3) | ||||
| 51.530 MHz GB2RS new broadcast and slow morse | ||||
| 51.910-51.950 MHz Internet voice gateways (10 kHz channels) | ||||
| 51.950-51.990 MHz. Can be used by RAYNET | ||||
| Note 1. Only to be used between station in different continents. | ||||
| Note 2. No QSOs on this frequency. Always QSY when working intercontinental DX. | ||||
| Note 3. 20 kHz channel spacing. Channel centre frequencies start at 51.430 MHz. | ||||
| LICENCE NOTES: Amateur Service 50.0-51.0 MHz Primary User: | ||||
| Amateur Service 51.0-52.0 MHz Secondary User: Available on the basis on non-interference | ||||
| to other services (inside or outside the UK). | ||||
| Notes to the Bandplan | ||||
| 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. | ||||
