Re: Back to the basics - tuning techniques

Probably the info you seek is here:


Or here:


The streamer load is about 2pF/foot in series with 220K once past the diameter of the top terminal. That can be used directly to calculate the streamer load and the lower primary tuning to compensate for it. All these numbers and programs can probably "calculate" better than you can "measure" ;-))

Programs like ScanTesla can probably give numbers far more accurately still... But your splitting hairs there ;-)) Unless you have crystal referenced measurement machines, "be happy" with the above ;-))

Hey All,

After running my first pig powered coil, I had the misfortune of blowing a capacitor. With subsequent rebuilding and retuning the coil is runnig smooth now. I blame the trouble with the initial tuning.

Question, I remember reading once regarding tuning with a frequency generator and an oscilloscope. Can anyone point me to such directoins? Is there any other method to get the tuning "just right" without relying on dead reckoning?
