I see I missed some posts. Sorry about that. Good news and bad news.
The good news is I swapped out my TX1 board using the same Nano and it appears the ghost readings are gone, so whatever was causing the readings is likely related to the TX board. But as with everything, time is the ultimate arbiter of truth. And now I have the unenviable job of figuring out what is wrong with the TX board that worked fine with the wind and rain, but not solar.
The bad news is now it appears there isn't enough gain, LOL. The sun is almost set, but the overcast sky is still back lit, and the other stations nearby are still showing solar readings, and mine is at 0.
While I was swapping the TX board out I reset the Solar/UV board to 4.7k ohms and I put the ADC1 wire back and twisted with the ADC0 wire. But at least it is now reading 0! Also set the clipping to 0.
