Hello,

I recently purchased two AudioMoth 1.2.0 units, and I have updated the firmware to version 1.12.1.

I have been testing continuous recordings at 48 kHz, using both the "Low" and "Medium" gain settings.

In both units, I consistently observe strong interference around 8 kHz and 16 kHz, regardless of where the recordings are made. The interference is always present, even when recording in different locations.

The only way I have found to significantly reduce it is to cover the microphone with my finger.

Have you encountered this issue before? Could this be related to the AudioMoth hardware, firmware, or microphone?

Thank you in advance for your help.
