Purely for my own amusement I've put together a few pages for when the web is not available https://docs.google.com/document/d/1xb9sJMiDvfoZdIDqJSDnHBfrCyRnc90DbRfcxi1DhsY/edit?usp=sharing
Question
1) Does the AM have a resonance, or excess gain at 20kHz? I tried a dozen indoor/outdoor settings, and there is always a band at 20kHz. The spectrum below is inside a quiet room. 2) In most of the indoor, quiet room, recordings, I see a rising thin line in the 30-50kHz range, see the above spectrum, the five panels cover about 20 minutes. Could this be a form of self-noise? 3) The clicking noise, I saw on other posts that this is SD card writing? I only see this occasionally. The image below was from inside a parked car at night - very quiet. Is the suggestion still to get the "Extreme" version of the SD card? Thanks - I love the unit. Keep up the good work - you are making a lot of research possible.
Hi David,
Thanks for this, really useful for users out in the field.
Cheers,

It's a very good summary even if you're not in the field. Perhaps needs to be on the AudioMoth website.
As regards "What do the LEDs tell you" I think "With Switch set to USB/OFF" should be amended to "When the Switch is moved to USB/OFF". This maybe a minor point, but would be more helpful to someone using the device for the first time.
Yes really useful, thanks!
Thank you very much for this doc, It's very useful to have it on hand !
Thanks!
