In a message dated 97-05-06 20:53:57 EDT, you write:

<< I'm having some difficulty measuring the inductance of my primary
coil -
 I
 think because of old and crotchety test equipment, but maybe it's just
 stupidity.  At any rate, I'm wondering - I have 13 turns of 1/4" copper
 tubing on a 30 degree bank, spreading out from 6 inches to about 25
 inches.
  Does anybody with a similarly-sized primary know its inductance?  (I
am
 just
 trying to get a benchmark, to see where the problem might lie.)  
 Thanks!!

Aaron,

Assuming your spacing between turns is 1/4", I calculate approximately
54
microheneries.
