Hey Guys, I'm new to audiomoths. I just purchased two. I'm trying to figure out a case situation for them. I designed and 3D-printed a case and discovered that I get noise and beeping if I try to record while the Audiomoth is in the case. I've also found that the beeping and noise happens if I try using a plastic bag as a case. The beeps look like this. Is this a known issue and has anyone else experienced this? Both audiomoths do it and they only do it when inside a case.
