Thanks Tom,
That calculator doesn't work for me for some reason. Every time I
tried to use it,it comes up with an error.
I have tried several different calculators but get varying answerers.

Hi Scott,
If My math is right I would need 23.5 turns of 12 gauge wire to reach
the same inductance as the original coil.

Sorry for what may seem like a repeat post,but for some reason I can
not seem to get comfortable with coils and inductance.

Thank You

I just ran the calculator at the referenced web site. It suggests
that you will have a hard time telling the difference between 25 turns
of 11AWG and 25 turns of 12AWG, wound on the same form and to the same
net length. The calc for the 12AWG shows inductance about 0.3% higher
than for the 11AWG. I'd have guessed it would be slightly lower. The
SRF's and Q's are similarly close, by that calc.

My feeling is that you are worrying the problem to death...

Cheers,
Tom
