The 2nd signal received on Longwave was BBC Radio 4 LW on 198 kHz. Amusingly, it was the exciting play-by-play of a game of Cricket.
As these two are essentially examples of 'local' reception, they're not any sort of accomplishment in terms of DXing. But I'm still very happy to finally have a chance to listen to something on Longwave other than beacons and other noises.
