[Elecraft] Time Syncronization

[Ed Stallman]

Unless I missed it no one has mentioned " Karen's Time Sync " From the 
time JT44 was introduced  I used Dimension 4 , as computers became 
faster and Op systems changed . D4 started giving me intermittent 
problems ! Two weeks ago I started using  Karen's Time Sync with no 
plans to change .

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.
