I think it was about 578kh.
I can try a lower number of windings, but I'm kind of thinking maybe I need a breakout point or a smaller topload?
Thoughts?

What are the resonant
frequencies of the primary + tank cap and the resonant
frequency of the secondary + top load as determined by
JavaTC? The secondary plus top load should be about 10-20%
higher resonant freq then the primary tank circuit to allow
for capacitive loading of the secondary plus top load by the
streamers.
Hope this
helps

Circuit: Bucket capacitor measured at .0145uF, 7 turns of

spacing = .25" I tried tapping it at 4.4 turns, 3.4
turns, and 6.4 turns.

Primary windings go in the same direction as the secondary.
Primary coil inside winding moves in a counter clockwise
manner towards the outside end and the secondary starts at
the lower side and winds in a counter clockwise direction as
it goes up to the top.
