Hi there.. I just built the Opentheramin v3 from scratch (soldered all components individually) and checked my work, it all appears good.
The LEDs come on and behave as they should while I calibrate it.
I can calibarate it, I hear the calibration sound when it starts and ends, but nothing else afterwards.
That is the antenneas (long wires for now) do not seem to pick up anything nor do I hear anything..
PS: I have an oscilloscope..
its calibration looks like this:

Any ideas what could be wrong?
Many thanks, -t
