Since everyone is locked inside a home the last few weeks I ordered an open theremin v3 PCB with separate components. I have assembled it. My initial problem was that something in the pitch block went wrong, causing a "frequency tuning range: 0 to 0" [color=#111111][font=Verdana, Arial, Helvetica, sans-serif]in the calibration debug. Although I did not order at gaudi.ch, I did get a reply from Urs it was likely my newby SMD-soldering. So after a day of puzzling I still don't get a tone out of the device. [/font][/color]For sake of convenience I have soldered some short electrical copper wires as antenna.

What works:

1. LEDs and button work, I am able to trigger a calibration, which I am also able to see happen.

2. When connecting the device to my amplifier, I hear the tones when it enters calibration mode, but I do not hear any other side.

I have a DIY oscillator (JYE DSO150) which shows me a sine wave on both antenna's when I connect it to ground. Is there any smart way to check the board when it is connected to the Arduino?

My calibration looks like this, notice that the set frequency is in both case out of the frequency tuning range. I would love to hear some suggestions.
