How do these time receivers work, Various standards bodies round the world broadcast an accurate time signal, backed up by an atomic clock with sub-microsecond accuracy. The German one is called DCF-77, is located in Frankfurt am Main, and can be received up to 1000 km away. I don't know if that includes your location, but it's likely that some other source would be available in Sweden. Have a look at http://www.igel.de/eiclock.htm for further details, but don't look at the prices. BTW, the $ price is significantly higher than the DM price mentioned in the German version of the page (http://www.igel.de/diclock.htm) > how much do they cost, I seem to recall the prices dropping to round the DM 100 mark (about $70) recently, but I can't be sure. > where can I get them? Offhand, at the office, I only found Igel. I'll check later when I get home. Greg
