ADC0 is twisted with Vcc, and ADC1 is twisted with Gnd. Should I separate them and twist ADC0 with ADC1 and Vcc with Gnd?
They can be also happens due to a presence of a very small voltage at the ADC0 input, 1 or 2 mV are enough.
Wires are just long enough to reach and no longer. Looks like this. I didn't bring my side cutters with me on the roof and I was racing in-between rain showers so I didn't trim the leads of the SP-110. LOL I'll trim them the next time I go up there.
