Back when it was “BBC Radio 7”, it had quite a few live programmes - so I imagine that the technical capability is still there, certainly.

Continuity on R4 Extra is recorded, unlike R4’s live continuity, although I am sure they can arrange continuity if required (probably from a spare radio studio).

Yes they had a series on Saturday mornings that was live links between the usual programmes.

All they need is a studio for the live programme itself, no need for any continuity studio or announcer. Other networks regularly mix pre-recorded and live programmes without the need for a continuity studio*. 4Extra isn't any different, it uses the same playout system as all the others



*although go back not that long and Radio 2 had newsreaders who acted as continuity. A friend of mine did some overnight newsreading there years ago and said it worked differently to every other station. Everywhere else the on air studio fades up the news studio.... at Radio 2 the newsreader faded up the on air studio between bulletins. A legacy that's now long gone
