I'm using one (with xntp). It's a cheap DCF radio clock interfaced (self-soldered) with the (otherwise unused) gameport. A kernel driver collects the received bits and a user level program filters the noise and sets the system clock. (Currently running on FreeBSD 2.1.5.) However, nowadays there are easier solutions, not requiring any soldering. One is an interface for the parallel port from Conrad Electronic, D-92240 Hirschau, Germany for ca. 50.- DM (incl WinDOS SW :-). I think also modules for the serial ports are available -- don't know about the protocol. Maybe s/o else on this list has experience with this sort of modules.
