Confirmation of OU devices and claims

I completed the 1 TX and 5 RX coils and put them in an initial setup, see picture below.

I noticed that there is some boundery around the TX in which the 5 RX coils perform maximum and thats at about  3cm distance.

Getting them closer will reduce the combined powers (probably due to the TX resonance (Q) deteriorate), putting
them further away also reduce the combined powers (probably due to loss to distance).

Putting 1 RC coil closer by the TX coil will rapidly increase its power, but the power in the rest of the 4 RX coils will drop.


Rough measurement taken with my PS which only measures the gate driver input shows an input of 540mW:

P=UxI
P=9x0.06
P=540mW

Estimate the FG input to be 20mW, so the total input power will be around 560mW (to be confirmed).


Each RX coil will give about 1V across 51 Ohm, so 19.6mW:

P=U²/R
P=1²/51
P=19.6mW

So the 5 coils together consume 5 x 19.6 = 98mW.

I will do some further testing and measurements this weekend.

Below screenshot shows a better input power measurement.

PS still at 9V, but now showing 0.07A (roughly 630mW).
The 5 voltmeters on the RX's show now in the 1.079 Volt range.

Measuring with the scope:

Purple: input voltage gate driver
green: input current gate driver
red:  math trace purple x green = input power
Blue is the input signal into the gate driver from the FG.

It turns out, each detector receiver consumes part of the transmitter power?
Will the ammeter switch on a large radio station, swing in a big way if I put on the headphones and adjust the variable capacitor to this frequency?

Since you are only using microwatts of the 10kW to 100kW or more being transmitted, it will not be noticeable.

Still doing some tests, but i cannot create more ouput in the receiver coils then stated earlier.

What i did notice with my hall sensor probe is that the max. RF coming from the TX coil is at its bottom, so the inverse as from a tesla coil.

The receiver coils are wired up the same way, so i guess they "expect" this max. RF at their bottoms too.
At least when i turn around a receiver coil its output decreases compared with its normal position.
