Sorry, I misunderstood about the video. I understand it is not your MD now.
With your TGSL, after modifying the sensitivity, what happens if you turn the pot to max sensitivity? Do you hear any beeping of any kind?
Please do this:
1. Put a jumper across your RX coil leads (shorting the RX coil).
2. Measure the DC voltage at the output of each LM308 with a sensitive voltmeter using millivolt scale.
3. Remove the jumper from the RX coil leads.
4. Measure the AC voltage at the output of each LM308 with a good voltmeter that can measure up to 15 kHz.
Tell us the results.
