Indeed, at the full hour there are 3 pulses (starting at approximately 0, 200, and 400 ms) and at noon there are 4 pulses. I didn't check midnight yet. > then you are hearing the Swiss radio HBG on 75 kHz. It looks like. But it is very strange, since the receiver should be tuned to 77.5 kHz. Also, we are only 55 km away from Mainflingen where the DCF77 transmitter is located. > The coding is very compatible with the German DCF77.

NTP doesn't like it: It inserts an additional bit for each extra pulse, and then it cannot decode the telegram. If I patch the inp_rawdcf function (in libparse/clk_rawdcf.c) to discard all pulses that are less than 700 ms after the previous pulse then the driver can decode the signal. _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
