Subject: RE: question about "lambda" (fwd)

Can't reply your first question, but

For your second question, it was Steve Connor(UK) who put this on the web. 
When you have a coil in perfect resonance, streamers breaking out ADD TO THE 
TOPLOAD CAPACITANCE. So the resonant frequency changes. If you you de-tune 
your coil, the topload breakout will pull the coil in tune. If you keep 
de-tuning, there will be a point where no breakout will occur.
