Hi,

I get 331.59mH
Medhurst C = 15.52pF
top 9 pF
Gives 55.72kHz

Seems like it will tune to a much lower frequency than you are expecting.

Cheers,

        Terry

Hi all,
  I'm getting ready to wind a 8.5" x 38" secondary.
It will have about 2533 turns of #28 wire.

  Is there any down side to this many turns?

Any feedback before I start winding?
                     Mike

P.S.
 My form is 8.5 x 42"
I figure about 3 lb of wire.
I think it's about a 280mh coil
Self resonant freq. should be 112khz
With a 9pf toroid should resonate at 75 khz
Have I made any errors?
