Dr Ronald Stiffler SEC technology

[NickZ]

   I've got my oscillator going, and lighting an led bulb on an AV plug. I think that that bulb may have been an AC bulb before being gutted.  My best output when running on 12v, so far, has been 39v, at the collector/emitter.  But, for some reason, the voltage starts to drop after a minute, or so.
   I've got it lighting on 12v, and just being careful not to overheat the transistor. I tried adding a 150K resistor in line with the 100k resistor that's on the base, but it would not start. And so I removed it, until I can find a more suitable one.  I've also, just had my first peak at seeing a wireless field effect, from this little oscillator. Lighting an led/AV plug an inch or so away. Finally!!!
   I'm excited... about my Exciter.

Thanks for the screen shots. Everyone having fun.  Hope you will forgive this comment, the projects are progressing nicely.
Some of the problems in years past has been matching first stage to the second with SG, variants, the nature of AC at RF.

I tried to find a video a professional good setup Zzz and also a hobbyist instruction so we can determine a good
impedance match.  Using a toroidal ferrite is one method of joining the signal to the amplifier for example.
The math and a little adjustment can give an outstanding result. An efficient transfer of energy.

Hopefully this will ad some content latter with Doctor Stiffler's concept and approach also not without electrical science.
The projects move toward understanding the SEC 18 hopefully get more definitive as it goes. (L3= ?Z) Crystal oscillator ?Z
On Impedance matching. Where to start ? output impedance, or input impedance, or maybe back and forth in small approximations.
Example: 10,000 ohm high impedance and a 300 ohm low impedance example could possibly use some math at first.

Slider,

something is not right i think, the signals are to small and wavy.
Are you sure your probe is ok, like is the tip firmly attached to the probe and/or is your ground lead
solidly attached to the probe (the lead sometimes breaks within the isolation).



Nick,

way to go, but are you running at 7.25MHz?




Microvolt,

thanks for the refresh on impedance, i think it will be important to take some impedance measurements of
the severall parts/components.

   Itsu:   
   I'm using the 7.2MHz crystal for now, as it shows the highest output at the led bulb. The oscillator will also run on the 13.5MHz crystals, but not as well. As that crystal runs the oscillator a few volts lower, like 32v, instead of 39v, like the 7.2MHz crystal.    Wireless field effects start to show up at around 40v, on, but are too weak below that voltage.
   Slider: I think that your scope's negative probe may not have been connected.

Hi nickz. you try 7.2MHz crystal on which circuit ?
thanks
