I think I got it this time. It is the geometry of the winds is all.
Look at the green winding with the spaces, capacitance and inductance. We get a frequency from that. The last youtube I made was driving just that with 4khz sine wave. I get ~8mghz out.
I realize this also looks like a shortwave antenna if the stranded was laid out straight. Then I remember the notched PVC coil has 2 of these GK coil primaries.
And I woke up!
If i have three layers of these windings with a slightly different spacing or wire length then I would be heterodyning in a circle. That means a rotating magnetic field.
If it travels across the scope screen then it travels in a circle.
Layer one tested with 4khz @ 140vdc. Screams at ~9mghz. I realized that is all there is to the lastest coil build. I can make a 3 layer, 4 quadrant tpu the size of a golf ball.
3 wire lengths. 3'8", 3'2", 2'8". The frequencies will correspond. An upcoming scope shot will tell.
I have my fet 6 inches from the coil and that equates to 140 volts with a jagged wave top. If I rasie the voltage to 242 then the wave top is very even on top, less ac wave part.
I like to keep my voltage down so tonight I will move the fet closer to the coil and put it in the center. My thinking is that is why the components are sitting on the ring. I know, why else. But it serves a purpose for the feedback of parasitic ringing.
top coil is 11.03 Mghz 18vpp
mid coil is 10.94 Mghz 19vpp
bot coil is 10.17 Mghz 28vpp
Serially connected bot to mid to top is 9.997 Mghz 19vpp
All in parallel is 4khz 5 vpp. No Mghz ringing.
Moving the fet closer after resonation starts does nothing. The ringing starts up immediately anyway.
The varicaps are in parallel for this test.
The vdc meter readings are taken when the oscillator side is always shut off. The meter readings are inconsistent when the oscillator side is turned on.
DC power supply across the fet, 100ohm 5 watt resistor, and bot coil has to be greater than 45vdc for the ringing to appear. Moving the coil nearer the fet at less then 45vdc does not actuate the resonation!
At 49vdc the ringing in chirp patterns starts to appear.
At 60vdc the ringing is solid and no chirping appears. I remover the varicap and the ringing stops, still at 60vdc.
No tank varicaps in parallel!
At 86vdc the ringing starts as the chirping waveform.
At 88vdc and above the chirping disappears into the full ringing waveform.
After the ringing is full on then raising the volts to 140 does nothing to the p2p of the gate ringing. Higher than 140vdc will give you headaches.
Hope this helps.
Another test I will do is to drive some of the coils on Mighty Little. I can almost predict the results. Short length, low turns count, fatter wire gauge relates to standard conduction. Large voltages can be applied to smaller gauges giving the better outer field generation. As the wire thickness increases we advance into higher levels of conduction if the voltage is not raised accordingly.
