Re: [TCML] Secondary and Primary Assistance



Hi Mike,

The primary outer diameter is 14.25"? That doesn't sound or look right. Did you measure one side at a time and forget to account for the secondary diameter? Seems it should be 17.75" which has an average turns spacing of 0.22" (edge to edge).

Looks to me like the secondary is using 24awg and about 710 turns with 3.5" x 16" dimensions.

With the 0.009uF cap, I assumed it tuned in at about turn 10?

Here's a Javatc output of how I looked at the coil (note Javatc uses radius's not diameters). The primary tune point is shown, not the actual primary turns. Of course, I might have some incorrect inputs, but that's how it looked from my arm chair.
