Hi all,

	I wrote some simple programs to solve the differential equations 
for a two coil resonant system. Plots of the voltages or other variables 
are made directly on an EGA (IBM compatible)or better screen. If anyone is 
intersted in doing cheap coil experiments, I'd be happy to send a copy.

Among things I've tested:
effect of the coupling coefficient, k, on the efficiency of energy transfer
"	" 	"		"   k, on the frequency splitting

Effect of Qs, Qp on the efficiency 

You can also easily see the effect on the voltage waveforms of the "magic"
K values of 0.6, 0.385, etc...
