Hello, I'd like to ask you for advice on setting up a NTP server on an isolated (i.e. air-gapped) network with a locally connected USB clock (Gude USB mouseClock II) as the only reference.
I have managed to get this set up, but obviously reception of the DCF signal is sometimes bad. We find "parse: convert_rawdcf: INCOMPLETE DATA - time code only has x bits" in syslog, and the output of 'ntpq -c cv -c rv' shows it is in state "bad format" every now and then. I failed to find a place on our site where this does not happen, and I already bought a second clock to rule out bad hardware. This alone probably wasn't a problem, but we also noticed ntpd dies every few days without any traces in the syslog. This morning, systemctl showed me that ntpd had exited on morning of 08/26, and the last log line was one of these "INCOMPLETE DATA" lines. No hint what caused it to exit. I guess this is related to the reception problem. Does anyone have experience with such a setup? There is a version of the mouseClock with a BNC connector for an external antenna, but it is quite expensive (~190€/$200), could this help? What antenna would we need? I already took a look at USB GPS receivers, but these too are quite rare these days and not cheap either.
