Thanks for the details! Helpful as always!

Cool, thank you. And I didn't put two and two together about the 3.5mm jack -- so the AudioMoth USB, it can serve as another approach for using external mics without needing to solder, like on the regular AudioMoth? That's a nice option for using a directional mic if needed.

Ah, what a bummer. But thanks. And I assume the rapid non-stop blinking from the red LED is a signal of circuitry failure, yeah? (I didn't see that particular blinking pattern mentioned in the documentation.)

Yep, though it sounds just slightly different/quieter -- like "better quality noise", ha. I just tried it with a different external mic, which wasn't part of the setup that got wet, and unfortunately got the same results.

Thanks so much, Alex!

Just wanted to comment with my own test. I recorded 30 seconds of silence with the AudioMoth in a quiet room on a soft couch and under a thick fleece blanket. The self noise measured -38dB to -36dB. That amount of noise narrows the radius of bird sound pickup I was hoping for, particular for the quality I was hoping to get for uploading songs and calls to eBird, but for ID'ing birds it's still pretty good. I'll post a screen recording of the self noise with audio below. A while back I got a good lav mic, partly with an eye (ear) toward using it to supercede the AudioMoth's own mic. But I'll need to find someone who knows how to solder.
