Hi all, is anyone aware of a published definition of the Wharton/W42 timecode protocol? I'm considering trying to implement an open source master clock for it, to help out a friend who has some ex-BBC clocks which use it, but as far as I can tell it's entirely proprietary and unpublished. Whilst I suspect I can implement something which syncs to NTP and spits out W482, reverse engineering the protocol is a whole other thing... Cheers, Dave W

The NTP daemon (ntpd) has a refclock driver for a Wharton clock: https://www.ntp.org/documentation/4.2.8-series/parsedata/#wharton-400a-series-clock-with-a-4042-serial-interface Maybe that description helps if you don't find some official specs.
