Hello, During the leap second, I recorded the (V)LF radio spectrum between 10 and 204 kHz. At my location in Enschede, The Netherlands, this includes at least four time signal stations: - MSF (England) on 60 kHz; - HBG (Switzerland) on 75 kHz; - DCF77 (Germany) on 77.5 kHz; - the French AM broadcast station on 162 kHz which also sends time codes as phase modulation. The first three use amplitude modulation, so their time codes can be directly read from a "waterfall" display. I've put such a waterfall picture with annotations at http://wwwhome.cs.utwente.nl/~ptdeboer/ham/sdr/leapsecond_dec2005.png (This is a temporary URL; I intend to make a proper webpage later, with more explanations.)
