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: 431-432MHz not available within 100km radius of Charing Cross, London.
Power Restriction: 430-432 MHz is 40W erp maximum
