I'm sad to hear the service has gone off the air. I was a constant listener to BBC Radio 4 on 198 kHz growing up in Dublin. It was a valuable window onto the world.

Listening to the last transmission there, I note that the continuity announcer, (the Irish) Al Ryan, signed off with 'oíche mhaith', i.e. 'goodnight' in Irish. A nice nod, I think, to all the former LW listeners in Ireland.
