That sounds "trivial" until you are 2 sec off one way and the other 50% are 2 sec the other way.

WSJT-x has a tolerance of over 2 seconds differential clock error between sender and recipient.  Therefore the solution becomes trivial:  If your computer is decoding signals seen on the waterfall, you are close enough.  If you aren't connected to the internet, as in "operating Field Day from a remote location without internet service (last weekend)" Meinberg will not help you.  However, the 1 pps derived from a GPS hockey puck or patch antenna is close enough to keep you whistling.  Second method: Find a cellphone app similar to HamGPS that can echo the cellphone site's 1 pps clock reference to your computer through a USB port, You can be up and running in near zero time.
