Yes! My best small/medium sized resonator is wound with Litz which a
sharp-eyed colleague who is not into coiling scored for me for $5!!
It is about 3" dia x 18" long (L around 20mH).
The mini coils are the only others I've built (much smaller) that
have performed beyond expectation and they were close-wound with
solid wire approaching 6 skin depths diameter. I didn't make any real
use of field control with those as they were a sight to behold with a
shower of streamers pouring off from halfway upwards.
All of a sudden I'm getting keen to revert to space winding as
tests show that I can do much better with smaller spaced wire. Looks
pretty too :)
