Thanks again, all. I did ohm out antenna, is fine. Changed power cables, supplies. Verified no bent center pins. This morning I got about 15-20 minutes into on time, she just stopped again- using wall power. Same thing, wait about 10 minutes and it would then turn on again. While it was on, was getting same all-over strength readings with unit perfectly still and pointed as close as I can figure to the F3 satellite as indicated by two different utilities. Varying from crazy low neg values to just over +1, about every second jumping. Also, removed antenna completely, and the readings are identical in behavior.
I have another CHIP board coming as this to me feels very thermal on at least the shut downs. I do have an RPI 2, but not a 3 on hand. I know all the docs say only 3 for the Outernet application at hand, but does anyone know if a 2 might actually work?
Back to the power topic, I notice the LNA says 3.3 to 5.5 V. Is this not the real operating range? Also, I very much want/need to use the battery pack generally for how I’ll be playing. Any idea what run time might be with the kit battery?
Happy New Year,
