Yikes! +/-30 secs and you might not even be transmitting when the other station is listening.
It's pretty well accepted that <1s is minimum accuracy for good performance. On EME you're looking for dT around 2.5 secs to help identify valid signals. If you're not within 0.3s, I'd be looking for a better solution. Dimension 4 worked great on my XP machine. When I upgraded last year to a much faster Win 7, per recommendation from EME guru W7GJ's site, I installed Meinberg which has been trouble free. Since K6QXY's computer for JT isn't internet connected, I got a USB puck GPS receiver and NMEATime from VisualGPS.net for Bob, and it's been an excellent solution. Software plus receiver around $50. I expected we'd have to put the puck outdoors, but it locked just fine laying on the computer desk. That's been my experience! 73, Josh W6XU Sent from my mobile device > > For what it's worth, plus or minus 30 seconds isn't all that big a deal. > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
