Mecanical or electrical noise ?
Hi everyone,
I got all my recordings with this kind of noise (in picture) on a Hydromoth Firware Basic 1.11.0. We used SD card SanDisk Extreme 64 Go.
Could it be the SD card when is writing? Do you have any recommandations?
Thanks,

Hi Alex,
Thanks for the clarifications! Yes, please find in attachment one WAV file. We used 3 piles AA Energizer lithium.
