1 INDUSTRY BRIEFING From Digital UK, the organisation leading technical co-ordination of the 700MHz clearance programme June 2017 Updated: 10 August 2017 Upcoming changes to transmitters in the STV region The UHF channels used to broadcast some DTT multiplexes at certain transmitters in the STV region will be changing from 26 July These changes are part of work being carried out for the 700MHz clearance programme. How will this affect viewers? Freeview viewers receiving their signal from a transmitter in one of the groups listed below may need to retune to continue receiving some TV programmes and radio services. Other platforms that use terrestrial TV, such as YouView, BT TV and TalkTalk, will also be affected. Most aerials are expected to be capable of receiving a reliable signal following the changes. However, some group C/D aerials may need to be updated. A wideband model is generally recommended. Help for viewers with reception issues will be available (see overleaf). Full details of the affected transmitters, multiplexes, frequencies and aerial group changes are listed at the end of this briefing.

Channelised distribution systems receiving a signal from one of the transmitters changing may need to be adjusted.
