List,

I have a theory that I came up with. I need to tell this story first:

One day, while in a theme park, I was waiting for a few friends to get off a 
roller coaster. Behind the bench I was sitting on was a fancy metal fence, 
and one end of it was cut off. I dunno why. But I put my finger on it, and 
started pushing on it slowly and steadily out of boredom. I kept the pace 
steady, and the section of fencebegan to bounce wildly. then, as the rest of 
the fence started to creak, the frequency of the fence lowered and my finger 
was no longer in sync with the fence. I thought about it, And I also thought 
about the swing so often used to descibe resonance. as the amplitude 
increases, the frequency lowers because the seat has a greater distance to 
travel. And the observation that makes me belive this:

I was fiddling with my coil one night. I had recently gotten it to work 
muuch better than it was by removing the topload completly. (just a wire 
now) It now throws a 10" streamer with half the original 1kW tank circuit. 
(still pretty bad, but improving...) I watched the length of the streamers 
carefully. They start off at 8", grow to 10" over a 3 sec. period, then 
stop, and start all over again.(the output never actually "stopped".)

I think it starts off at a high frequency, and then lowers as the amplitutde 
increases.  It would be real hard to make a primary do that...

Anyone else have this happen?  Comments?
