Please see http://www.meinberg.de/english/info/dcf77.htm, the page
contains a short paragraph concerning the pseudo-random phase noise of
DCF77. Our PZF models (like the PZF 509) are able to get in the range
of microseconds and this is something other DCF77 receivers do not 
archieve (AFAIK). If you know of any other receivers using this
feature of DCF77, please let me know :-)

Kind regards,
