Falcon MD20

[kt315]

copper ring is for fine tuning of sensitivity. no trouble here. just some good and simple tech decision.

Hi , what I am saying is I own a factory made Falcon, made by the seller, if you are trying to make a copy the hardest thing to make would be the coil, the location of the copper ring is sensitive, I have not tried to make a copy.

The copper ring acts like a target, the closer to the coil the higher is the loading of the oscillator, which means the amplitude of the oscillation decreases and the Q is lower, it reduces the senitivity. I wonder why the manufacturer went to so much trouble, as it complicates manufacturing for no gain.

Thank you very much. 6666
Have you done the coil already?
Stable?

I have a real Falcon, it works well, the tricky bit to making one would be making the coil with copper ring
