Hi, I'm newbye in thi world, I have assembled a Chinese version of open Theremir V3.
I have calibration problem, the frequency tuning range, it is out of value for the pitch.
I have tried different antenna configuration, but I can't modify this range.
It is a grounding problem?
I have checked every single component (is my first smd soldering) it seams ok, I can't check the integrate component but all seam work.
this is a bit of the output:
