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 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: All Internet voice gateways: 12.5kHz channels, maximum deviation +-2.4kHz, maximum erp 5W (7 dBW), 
attended-only operation in the presence of the NoV holder.
Note 10: May be used for Emergency Communications and Community Events
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 
Note 14: QPSK 2 Mega-symbols/second maximum recommended
   
LICENCE NOTES:   Amateur Service: Secondary User.    Amateur Satellite Service: 435-438MHz: Secondary User
  Exclusion: 431-432 MHz not available within 100km radius of Charing Cross, London.
  Power Restriction: 430-432 MHz is 40W erp 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.
