In a recent post Dr. R.  mentioned that with a high power large secondary a 
conical primary will overcouple , I am in the process of building a coil 
with a 12" secondary and a 16 turn 30 degree inverse conical primary, power 
initialy will be 4 15/30 nst's with SRSG 120 bps , will overcoupling be a 
serious problem ? should I rebuild the primary to flat spiral and replace 
the SRSG with a sucker gap? could someone tell me what some of the effects 
of overcoupling are? I can also raise the secondary about 5" if this would 
lower the coupling equal to flattening the spiral.......suggestions?

thanks
