This one https://www.youtube.com/watch?v=3ehz4MT8ec8It's all Cepren's workI suggest you watch them all, you have much to catch up on.
this data might be of help to some of you while winding this device, of course the frequency with your catcher might be different but i'm sure you could build your own coil winding data base coil winding relationship.http://www.procato.com/calculator-wavelength-frequency/Wave length to meters1.67mhz 179.51644191616765 meters3.34mhz 89.75822095808383 meters 2nd harmonic 1 wave5.01mhz 59.83881397205589 meters 3rd harmonic 6.68mhz 44.87911047904191 meters 4th harmonic ¼ wave8.4mhz 35.68957833333333 meters 5th harmonic10.02mhz 29.919406986027944 meters 6th harmonic11.69mhz 25.645205988023953 meters 7th harmonic13.36mhz 22.439555239520956 meters 8th harmonic15.03mhz 19.94627132401863 meters 9th harmonic16.7mhz 17.951644191616765 meters 10th harmonic=======================Version 238 metera 7.889275210526315 Mhz19 meters 15.77855042105263 Mhz
All this demonstrates is that your calculator can spit out meaningless numbers after the decimal point. This is FALSE PRECISION. I challenge you to tell the difference between 7.889275210526315 MHz and 7.889275210526316 MHz, or between 17.951644191616765 meters and 17.951644191616764 meters using any actual measuring device available to anyone. The general rule in these matters is that you CANNOT have more precision in your result than the LEAST precise number that goes into the calculation. So saying, for example, that 19 meters = 15.77855042105263 Mhz is simply wrong, even though your calculator might spit out all those numbers as the result of a numerical calculation. The best you can say in the reality of actually measured quantities is that 19 meters = about 16 MHz. Or 19.00 meters = 15.78 MHz. Or that 19.000 meters = 15.778 MHz. Get the idea? This is the concept known as "significant digits" or SigDigs for short. Avoid false precision, as the more digits you have in the result of a calculation involving measurements, the more likely you are to be wrong.
Now I don't get the high frequency ringing any more, but just a single pulse that is limited [/size]at a lower peak voltage. This is causing diodes D3 and D4 to get hot with V+ set only to 12V. With V+ at 24V it looks like they could well burn.
Maybe try use shottky diodes 40-100 V?
