Matthias, I have a similar configuration with a simple DCF77 receiver connected to the serial interface of an old Sun.
The clockstats show poor signal reception: refclock_states="*NOMINAL: 27d+16:12:06 (54.58%); NO RESPONSE: 2d +23:36:07 (5.88%); ILLEGAL DATE: 20d+00:53:58 (39.52%); ILLEGAL TIME: 00:04:24 (0.00%); running time: 50d+16:46:35" but NTP is ticking happily: offset=-0.007, frequency=-22.766, jitter=0.539, noise=0.627, stability=0.000 The refclock driver is doing a good job of checking the validity of each DCF77 'telegram'. If a telegram is invalid, NTP freewheels until reception improves.
