RE: DRSSTC Tuning Paper (Rough Draft)

Original poster: "Mccauley, Daniel H" <daniel.h.mccauley@xxxxxxxx>

Here are the coil specifications:

Toroid:  13" x 4"
Secondary:  4.5" x 12" winding length
Secondary Wire:  30 AWG
Primary Coil:  Approx. 5.75 to 6.00 turns of 0.25" tubing (0.20 spacing)
Primary Capacitor:  0.108uF

Secondary Coil 1st turn is approximately equal to the top turn of
primary coil.  Spacing between toroid and top turn of secondary is about
2 inches.

Hope this helps.


thanks for the information. JAVATC uses raw geometry to calculate the
resonant frequency, coupling factor, recommended tuning point etc. So
it would be easier if I had some of the coil specs. However, I can
input some guesses until the electrical parameters match what you have

I assume the Cprimary is 0.108uF.

The actual tuning point is shown in the paper.  This equates to 9.2uH of
primary  inductance.

Lsec= 39mH
Coupling = .14 (for 9.2uH tuning point)
Cpri = 0.108uH
Csec(total) = 17.5pF
Rsec = 150
