If i understood it right, it's a normal single-wire, single-layer air-core coil. Nothing special. The only parameters which can be varied are wire size, coil diameter, and number of turns. But even if my coil has not exactly the right parameters, it should have a resonence somewhere, and this could be tuned to the desired frequency by varying some parameters, like numbers of turns for example.

Looks like you are spinning some theories here without even having done the most basic experiments...   :o

I have wound many coils and built multiple resonant tank circuits. I don't have a scope. I know from experience that you can strip windings back, and get the correct (SRF). You can get nearly close enough with the formula, then the scope work is needed. Stiffler's coils are like precious jewelry. I don't have the precision instruments needed to craft one.

I would offer to buy one from you if you could make one that works. You would find people behind me in line.

@skywatcher,


I would order a gross number if you could help find an outfit that would be willing to manufacture them with high tolerances.

OMG... that's a really serious problem.  Hint: You can get one for free, there are companies throwing out perfectly working digital scopes on the junkyard only because they are 5 years old and so they 'have to' buy new ones. I'm currently using such a scope for which i didn't pay a single penny.

What precision instruments you need for winding a coil ?  These instruments are called 'fingers'. 


As i already said, the problem is not tuning the resonance, the problem is that there is not even a resonance, so i don't know what i should tune...

This is my coil:

I just submitted an order to "Sag Harbor" industries for an estimate on the manufacture of the coils. I know what you're talking about because no one else can figure out how to do it either. It's like trying to make a transistor.

Professional equipment is really needed for it to come out right.

This is Lidmotor's coil. I can not see which wire size he used but the size of the coil is not so much different from my coil.
Maybe it's slightly bigger. But this should not matter because it can be tuned.

 Jonnydavro's L-3 coil is 620 turns of 26 swg wire.

62 of 26? Further evidence of "Mayan Synchronicty"? The "Runes of Saknussemm"? (Fictional character in Jules Verne novel) We may need the lagina brothers!

I got some hints how to measure the SRF (use a 1-turn sensor coil around the coil) and now i'm at least seeing a resonance... which seems to be slightly above 20 MHz so i have to make the coil a little bit bigger.

You're on the right track. Dr. Stiffler makes mention of a "sensor coil". Keep it up, it's getting really exciting. Can you upload a video? They may act as "Crystal Receivers" for a Quantum radio club.

I will buy a scope if you can show me how you made one that works. A lot of people would benifit from that kind of instructional video.

I made a new coil with 32mm diameter. Initial length was 53 mm.  SFR was 8.08 MHz.
So i removed some of the windings... at 40mm length it was 9.48 MHz...
Now i'm at 12mm length (almost nothing left  :o ) and it's at 11.04 MHz.
But i'm getting a second peak slightly above this frequency... 


Maybe i will go back to the 12mm coil.

What wire gauge are you using?

Jonnydavro's ratio would be 620 turns of 26 Swg = 0.018” / 0.457mm.
620 turns of 0.457mm wire would give a length of 283mm.  Which core diameter ?

Here's one from Blumoon:

L3= 100 turns of 0.3 wire on 3cm plastic tube.

Two coils, built to the same (SRF) in that wavelength, connected to two variable capacitors and tuned to high "Q" resonance would send a short wave signal to a receiver over International distances through an antenna and ground. Tesla patented this "Double Tuner" and it's known as the "Ham Radio".
