Can anybody narrow down what this noise on my Lectro SMDWB's might be? I've tried different mics (all cos11d), different batteries, different frequencies, different microSD cards and it's happening on both of my SMDWB's. Seems to be only when recording directly to the microSD.
First file is while recording to microSD. Second is recording to my 633.
Apologies for the standard "Hey Hey Hey" Check.
