This is the first time in the UK that a whole region will switch to digital only television. The process will see the existing five low power Freeview signals turned off, and then the analogue FIVE, Channel 4, ITV1 and BBC one. This will mean that for the first time in 47 years there will be no analogue TV signal from here.
Then the new high power Freeview signals will start transmitting. This will happen first at Selkirk, and then in the following half day, the rest of the relay transmitters.

If you are on a relay - and have only the BBC channels on your new Freeview box - you may need to rescan for channels during the morning, but you might have to wait while the engineers ensure the whole region is working.
