you have big massive metal under/near the table. nobody is able to help you

Ok, now I will test vertically with a small coil

while your coil on table (not moving) you do not need in ESFP. no need the shield.

it is impossible even without foil!!!

You could also try an omega coil. It has almost the same characteristics as a concentric, but is easier to construct.

Why can't the rx wavelength be steered left and right so that I can adjust the 20 degree difference? I can only shorten or lengthen the wavelength by moving the coil.

good example that the foiled coil is not possible be balancing. now time to re-go on STANDART way, be back on, graphite layer shield way.

in russian. ЕСЛИ НЕ ДОШЛО ЧЕРЕЗ ГОЛОВУ - ОБЯЗАТЕЛЬНО ДОЙДЕТ ЧЕРЕЗ НОГИ И РУКИ. russian army Rule.

If the problem is foil, I have a coil without foil, I will test it right now

big mistake that you do not see differencies between electromagnetic field and electrostatic field, EMF protection and ESF one, respectively.
i call somebody to give you The First Lesson here (better 2-3), be cause my english is very poor. english speaking guys will help.

The problem is solved. The volume volt/did had a problem. Now I can see it on 10 mv. I set the rx to 2.2, which is 2.2 x 10 = 22 mv, but nothing has changed. See, the rx does not move to the left or right at all, until I see the phase difference 20 degree between Rx and Tx!!

foil shields if tx and rx are touched. it is mistake.

So this is also mistake because it says that both shields must be connected

[kt315]

foil shields if tx and rx are touched. it is mistake.

You can null an unshielded coil, but then when you apply shielding usually the null will shift. The cable should have a minimal effect, you can test by moving it around.

I tried everything, but nothing changed. Up to 200 mv it can be seen correctly
10 mv is impossible

[kt315]

your photo is sad for me. you put fat (cabel) shield on coil and wait good balance that impossible.
what to do. turn over the coil so the cable has to go down, on floor. pass the cable via a hole in table. i write just as example for understanding.
your cable to the coil must be sheerly, in a space, to be less influence of the metal on the balance.

experiment with small piece of copper or closed copper wire ring.
1 change the size of it
2 change a place of it between windings

This is a good trick for altering the R-null, but what I see looks like mostly an X-null problem. You could try moving a small piece of ferrite around the windings.
