Sometime around 1990, Unix added the adjtime(2) system call. This allowed changing the frequency of the system clock, typically by adjusting how many wall-time ticks were added per hardware clock tick. If the clock was stable but off frequency, progressive adjustments (compared to a reference clock) would get it very close to the right frequency. This is pretty much always done with NTP, the Network Time Protocol.
If the KX3 clock is stable and is adjustable, the KX3 Utility could do this. Tweak the rate a bit each time the clock is set. If the KX3 clock isn’t stable with temperature, it isn’t worth bothering. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Aug 28, 2016, at 4:43 PM, Jim Brown <j...@audiosystemsgroup.com> wrote: > > I don't know either, but need accurate time on my computer to use the various > WSJT modes.
