In the Border Scotland area, those receiving signal directly from the Caldbeck transmitter will continue to receive the radio services, as long as they are tuned into the English radio services from the mast on C25-. This may require a manual tuning on a Freeview box.
The BBC did consider pulling a "red button" channel during 5pm-midnight, and also the unwatched (but politically important) BBC Parliament channel, but decided that this would cause "likely loss of significant public value". Quite why BBC Parliament could not become an audio-only or quarter-screen service is not explained.
The BBC will be providing at least an extra eight national DAB transmitters in Scotland during 2011, which will mitigate the problems here somewhat.
Kevin Finn: No, this channel is only available on muxes carrying BBC Scotland, ie all Freeview transmitters in Scotland plus Caldbeck. The service is available throughout the UK and some other parts of Europe via satellite.
