Open Theremin V3, volume oscillator not working

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.

CALIBRATION COMPTLETED

I have built many v3s and encountered many problems. Usually correct automatic adjustment, serial port output will be two digits. If not, there is a problem. As for the situation that the volume does not change, what I have encountered is that the ic4060 is damaged. I haven't found the real reason for the problem that can't be adjusted automatically. I check all the components one by one, and they are all OK. When I replaced the PCB, everything was OK. If you need, I can provide PCB manufacturing documents. I have made some modifications to the original version and removed unnecessary pads.

When you look at the calibration process, you see that both variable oscillators, pitch AND volume are running 110 to 120kHz too high, which is beyond the range which is foreseen by design and which can be adjusted with the calibration procedure. Thus it’s logical that the calibration procedure times out without success. The tuning range has to go from set frequency -2kHz to set frequency +2kHz. Since on both sides, you have a ~20% too high frequency, this is an indicator that there is a systematic problem with components in the analog oscillators, such as for example c2, c3, c9, c10 only 100pF instead of 150pF or l1, l2 only 560uH instead of 1mH. 
With correctly built oscillators and well dimensioned antennas, the pitch tuning range is about from 498 to 502 kHz and the volume tuning range from 458 to 562kHz. Without antennas connected, these values are about 5% or ~25kHz higher (which might make the calibration fail) but never as high as you reported.

@thierry I read what you write. I have some questions though.

 - could my antenna material or length be the only reason for this 20% too high frequency?
 - is it possible to address this in the software, hence move the allowed frequencies higher?

The problem can have many causes, but the length and material of the antennas can significantly affect the quality of the setup.

@Valery for me 'quality' would mean the precision with respect to able to play the instrument. I wonder if it would have the major influence the capacitance, the PCB, materials or soldering is more at play.

- As I already wrote, the antenna material and geometry is not responsible for such an extreme frequency deviation. Without antennas at all (extreme case) you’ll run 5% high, not 20%.

- Your problem can’t be fixed in software since the reference frequencies (set points) aren’t controlled by it, these come from the 2 xtal oscillators on the shield.

To me, there is no way around checking and fixing or rebuilding your variable oscillators.

I am sure I have used the right "labeled" components, that does not mean that the components were labeled right obviously. Could you recommend any path for debugging the issue? With too high, would you recommend ordering new capacitors and redo soldering, or is it more likely that there is a short circuit or what is the best way to check ic4060?

I didn’t say that it was your fault, I’ve already seen full batches of wrongly labeled components which were sent to me by a renowned distributor. That’s why I check every single component with a RLC-meter when building circuits by hand.
I pointed you towards the 6 most crucial components which I would unsolder and check, first.
The 4060 ICs (U2 and U3) can be simply checked with an oscilloscope and a frequency counter: Pin 7 of U2 should show a square wave with 5Vp and 500kHz, Pin 7 of U3 the same but at 460.7kHz. If both these are ok, you have several confirmations: 1.) The reference oscillators work both as expected and 2.) The problem is really with both analog LC oscillators and you should proceed as I wrote above. If both these weren’t ok (what I think is very improbable) please write back with the results of your measurements.

Thierry do you have any tip to run this board without the arduino attached, so it becomes possible to probe?
