I've been hacking LW time signal receivers for at least a couple of decades, always liked DCF77 because of the additional 512 count sequence (both it and MSF are great intro's to RF hacking in the UK/EU). I'd still got recordings of LW time signals from MSF, HBG and DCF for the midnight rollover from 1999 to 2000 (they didn't all get it right :) ). It's not well known, but quite a few LW transmissions also carry timecode. TDF Allouis in France and Radio 4 in the UK (R4 is pretty cool because it also carries certain 'additional data'). A couple of source that went off air relatively recently were HBG75[[0] and Loran [1].
