Improving DCF77 reception over longer distances
While working on their open source hardware Nixie Tube Clock, guys over at the Electronics-Lab.com are also working on DCF77 time synchronization part.
The DCF77 transmitter is located in Germany (Frankfurt) and they are trying to receive the signal from a distance of more than 1500 km away. They did some interesting testing with different antenna sizes and posted their results online: "It seems that antenna selection affects received signal quality, bigger length and better tunning plays significant role in reception in long distances form DCF transmitter. So if you plan to use a DCF receiver on long distances, look for a better antenna."
