RE: [dxatlas] Faros technique at VK4IU
- View SourceHi- My timing marks look nothing like these. I sit on 21.150Mhz beacon and
see it pretty well. Looking forward to some m ore info on Faros and timing.

Further to my investigations for accurate time within Faros, I have updated
the images on Google <http://picasaweb.google.com/Faros.VK4> to
include several days of observations of JA2IGY 14MHz in VK4. The
images are at approximately 15 minute intervals. For each of the UTC days in
November, if you change the display to have four images per row, you will
find it easier navigate the data.
Any comments on the data are welcome.

- View SourceHi Both.
This is just as well mentioned here as anywhere else.
I've been experimenting with the Windows port of NTPD by Meinberg.
Faros works with it quite well, (it's on a seperate PC at the moment.)
NTPD in turn is at the moment taking it's sync data from the 'net.
However, the NTP issues caused by the WAN here (ISP or carrier who
knows!) still causes problems, just that it takes longer for them to
show (and to recover.) But the overall Faros timing behaviour is
slightly improved, just by having another NTP server between it and the
outside world. Different algorithms and filters in software I guess.
I don't know enough to say for sure.
I still plan on getting the Meinberg NTP server to run from a GPS, but
though I've now discovered what I did wrong before, I've yet to "get
enough of the right sort of time" to try it again "the right way".
More news one day.
Idealy, I'd like all that to live on the same physical PC as Faros. As
above. "One day".
