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...

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.

I don't have a scope.

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.
