[VHFcontesting] Time sync app for JT44 portable operation...

JT44 requires aprox 1.5 second timing accuracy to work. Since I will be
on a mountaintop this weekend, I needed a way to get Atomic Clock
accuracy without an internet connection.
I found an excellent app at http://www.kaska.demon.co.uk/ called Tardis
2000. It uses the standard internet time servers as well as any GPS
that supports NEMA output. I'm using a Garmin EMAP and it works very
nicely. This will be great for anyone who wants to try JT44 -- even
perhaps a rover who is stopped for the night in a good location who
wants to try some long-haul tropo.
Tardis is a networked app, and can serve as a time server, driving such
programs as AtomTime. So if your a multiop and you have networked
connectivity, you can use it to time sync the entire network.
I'm still looking for anyone interested in trying a long-haul tropo
sked in the wee hours via JT44... anybody interested? Let me know
and I'll stick it in between HSMS and EME skeds.
