RE: [TCML] Interesting pages on Q factors

["Jim Mora" <wavetuner@xxxxxxxxx>]

Hello Friends,

Who else has done coil analysis of high Q coils?.  My 8" coil which was
wound with 22 Awg 200 degree insulation and coated with oil based Poly. A 4
to one ratio, the secondary's Q was somewhat disappointing where the degree
15 turns was very high and was coupled to a .03Uf cap. Of course throw
enough power at it and it does very well.

My next coil will be 22" to 24" very well dried and coated inside and out
after the coating is removed.

Perhaps DC Cox or Jeff P will chime in with their experience with these
sized coils. The Q is largely a test of quality of a great verses a weak, so
so coil. I want a very sharp peak, not a wimpy one that is hard to turn too.

Thanks, Jim Mora
