Currently in the field where I deployed two Audiomoths, that were tied on a tree (next to each other). Each recorder was tested with different batteries to test how long they last (Duracell and Eveready). I am currently using a San Disk Extreme - UHS 3 as recommended and the latest firmware - 1.3.0.
After 3 days of recording, when I retrieved the memory cards, I see a ton of white lines at high frequencies in almost all of the recordings. Why is this happening? What's the solution?
