So, in the end...
1. We had to go in and tighten the connections to the antennas, etc.
2. We had to re-flash the primary and backup cards...all working well now.
Just odd how this is about the 3rd time we've had to do this....and I am super-careful about shutting the stratux down through the commands on Ifly. I never just pull the power.
Anyway, I will try to refrain from ever doing a re-boot while flying - somewhat distracting.
