| Note 1: In Switzerland, Germany and Austria, repeater inputs are 431.050-431.825 MHz with 25 kHz spacing and outputs | ||||
| 438.650-439.425 MHz. In Belgium, France and the Netherlands repeater outputs are 430.025-430.375 MHz with 12.5 kHz spacing | ||||
| and inputs at 431.625-431.975 MHz. In other European countries repeater inputs are 433.000-433.375 MHz with 25 kHz spacing | ||||
| and outputs at 434.600-434.975 MHz, I.e. the reverse of the UK allocation. | ||||
| Note 3: IARU Region 1 FAX/AFSK. | ||||
| Note 4: ATV carrier frequencies shall be chosen to avoid interference to other users, in particular the satellite | ||||
| service and repeater inputs. | ||||
| Note 5: In other countries IARU Region-1 recommend 433.450 MHz for DV calling | ||||
| Note 7: Users must accept interference from repeater output channels in France and the Netherlands at 430.025-430.575 MHz. | ||||
| Users with sites that allow propagation to other countries (notably France and the Netherlands) must survey the proposed | ||||
| frequency before use to ensure that they will not cause interference to users in those countries. | ||||
| Note 8: Internet voice gateway channels: maximum deviation +-2.4kHz, maximum effective radiated power 10W (10 dBW) | ||||
| Note 9: The beacon band in the UK is scheduled to change to 432.400-432.500 MHz when agreed by the Primary User. | ||||
| Note 10: No longer used. | ||||
| Note 11: IARU Region 1 recommended maximum bandwidths are 12.5 or 20 kHz | ||||
| Note 12: Embedded data traffic is allowed with digital voice (DV) | ||||
| Note 13: Simplex use only - no DV gateways | ||||
| LICENCE NOTES: Amateur Service: Secondary User. Amateur Satellite Service: 435-438MHz: Secondary User | ||||
| Exclusion: 431-432MHz not available within 100km radius of Charing Cross, London. | ||||
| 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. | ||||
