UK 70cms Band Plan (430-440 MHz)
UK 70cms band plan for 430-440 MHz, or UHF for amateur radio operators. Foundation and Intermediate Licence holders are advised to check their licences for the permitted power limits and conditions applicable to their class of licence.
All band plans are based on the IARU International band plans, however, there may be slight variations to allow for local regulations. This 70cms band plan is for UK based radio amateurs.

Notes to 70cms band plan
- 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. - ATV carrier frequencies shall be chosen to avoid interference to other users, in particular the satellite service and repeater inputs.
- In other countries IARU Region-1 recommend 433.450 MHz for DV calling
- 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
- 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.
- May be used for Emergency Communications and Community Events
- IARU Region 1 recommended maximum bandwidths are 12.5 or 20 kHz
- Embedded data traffic is allowed with digital voice (DV)
- Simplex use only – no DV gateways
- QPSK 2 Mega-symbols/second maximum recommended
- Exclusion: 431-432 MHz not available within 100km radius of Charing Cross, London
- Power Restriction: 430-432 MHz is 40W erp maximum
