I can't think of why the sparks may get longer over time; usually with a 
poor gap, they get smaller over time.

I didn't understand the dimensions of your toroid - 22.5", 52".  22.5" is a 
reasonable major diameter.  What's 52"?

For your RQ gap, how was the number of segments determined?  How many and 
what is the segment spacing?  If the total gap is too small, performance 
will suffer.

Do you know if your pri-sec coupling is good?  Can you bring the secondary 
any closer to the primary, or do you already get racing sparks up the side 
of the secondary?  If the coupling is poor, performance will suffer.

To continue with my toroid troubles, my secondary is 22.5 inches closewound
22 AWG, primary 13 turns 1/4 copper tube spaced 1/4 inch and tapped at 6.25
turns (my LC meter reads 16.6 uH.) My saltwater cap. measures .013 uf .
Small RQ
style gap w/ muffin fan, toroid is semi-rigid ducting- 22.5", 52". My power is
a 15/60 NST.
No sparks without a tack!
When tuning using 30% power, sparks develop slowly. Also at full power w/
breakout point- they sputter and get slowly longer over time. Anybody know
what
this means?
Thanks in advance,
Robert Hanford
