Richard VIALLE's new theory about negative mass and overunity

[Khwartz]

Hi Khwartz,
  thanks

I'm considering buying one of these SWR meters - 1.8 - 525MHz:

I'm considering getting into CB radio - to make the purchase worthwhile... lol. Actually - I'm planning on doing a load of experiments with HF eventually too - such as John Kansias's burning salt-water, Hutchinson effect etc... So i'm sure it'll be useful.

I'd like a VNA - but I'm not sure I can justify the expense of buying one... I'm still mulling the idea of making one, but I can't even get my ZVS driver going...

Hi tim

I think what ever you'll do will be a step in an positive direction

If you need financial support, I think I can help you up to 50€ in the next weeks, for the verpie's wattmeter or your NVA built. If you're OK, just PM me data for sending in PM.

Best regards,
K.

However, you cannot trust non-inductive bulbs to accurately indicate input power (because in that case the bulb is not the indicator and load in one - it is merely an intermediary between the power supply and a 3rd element in that circuit...

Hi Verpies,
  in this case, isn't the bulb the DUT? As we're trying to measure the power through it - and there's nothing else in the (output) circuit.

Also I have a couple of questions that perhaps you could help with:

1) The driver for the Vialle gen is clearly the most important part, and the hardest to get 'right'...

What do you think would be the 'best' way to drive the device - given the requirements of:
- High efficiency,
- Variable, high frequency
- Balanced output, sine-wave oscillator

For example, I have a linear amp - with a D1020UK, MOSFET. Balanced push-pull type. I've not used it yet. I'm reluctant to hook it up to the VG in case i kill it. That MOSFET is cool - but expensive. Is there anything similar but cheaper you know of?

A multipactor might be good. Shame they're not available to buy these days...(?)

I would like to be able to explore the higher harmonics of the series that is apparent in my device: 3.7, 7.3 MHz found, - so 14.6, 29.2 may be there too etc... Although the reactance of the coil may prevent them...

2) I think it's clear that there is capacitive coupling between the coil & tubes. The fact that putting my hand near the device makes the bulb go out is compelling evidence. Also, it would be remarkable if there wasn't, so:

I'd like to cancel out the electrostatic part of the equation - so we just have the magnetic component... How could I best do that?
- coil with 2 layers, one wound CW, the other ACW, drive one layer -ve, the other +ve...?
- shielding?

Tim,

What is the difference between:

- Touching a device changes the tuning and so the output by changing stray capacitance

And

- The device works by and because of capacitive coupling?


BTW, is that my translation so bad that the tests to check capacitive coupling looks not relevant for you? But true that verpies could suggest other relevant stests, so...

Hi Khwartz,
  I don't know. It's a good question... Changing the tuning would decrease the magnetic field... It would be so useful to have my ZVS driver working - as it auto-tunes...

If it does change the resonance - and the bulb then lights up at a different frequency - what would that mean I wonder?

BTW, is that my translation so bad that the tests to check capacitive coupling looks not relevant for you? But true that verpies could suggest other relevant stests, so...

No mate, it wasn't bad. I was just wondering if there was a way to cancel it out completely in the device itself - so I didn't have to try doing those calculations...

I could do the alu-foil shield - but i believe what Pascal said - and I'm not sure if it helps...?

I was also wondering if perhaps the cap-coupling might interfere with the desired effect - i mean - it's supposed to work because of the magnetic field - but maybe the electrostatic field is interfering with it... Just a thought.

The best idea i can think of so far - but it's not perfect - is the 2-layer counterwound coil - fed with balanced + & - signals... That way the 2 counterwound coils would make the same magnetic field - but the electrostatic field would (more or less) cancel out.

Maybe it would be possible with a normal bifilar coil...?

Correct, the output bulb is the DUT and a power indicator in one.
However, the input bulb is not the DUT.
