I am located near Frankfurt, so the distance should not be the problem. Even 
in the basement I can receive the DCF77 signal. I played around with the fudge 
time1 parameter. At the moment I have it set to 

server 127.127.8.0 mode 19
fudge 127.127.8.0 time1 0.009

But until now I could not find a good value. 

Thanks for all of your help and your suggestions.

Regards
