I used the base while spraying this afternoon.  It obtained an immediate fix on my Pro 700/372 and was off by the same 6" that my FMX was off yesterday while I was working on adjusting the ENU location.  I was able to shift my line over and sprayed 80 acres without any issues. At about 4:00 I started loosing my correction with a message saying GPS satellites lost.  I was almost instantly able to engage and keep going but it happened many times.  I then changed to my RTX to finish.

I hope NNielsen can look at my stream history.  I suspect your comments about having to few satellites receiving both L1/L2 is my issue.  I setup the Mosiac X5 soon.
