5x5 LED field & 2 directional antennas

[Funfinder]

If the method described in my last post really works,
any LRL must have at least 2 antennas - one left and one right -
so it is directional and can show the output of the stronger growing
signal either on a screen or at least on a LED field!

No wonder if those so far low-level-LRL-detection-signals are vanishing
all the time if someone comes closer to the source - the circuit just
starts geting overloaded!

I have created an animated gif so you see how the output of
such kind of detector REALLY has to look like!
It will directly shows from where the signal comes and how
intense it is - exactly what is needed.


But if the detection of eddy-currents, created by very weak longwaves
from far far away, really works and how good or reliable, still remains a
completly different question. This needs tests first with long-wave-transmitters
from different distances and from very weak to stronger TX-output, so it will
be absolutly clear from what field-strenght upwards the high sensitive LRL-receiver
starts to be able to detect anything at all and how reliable this stuff works.

You LRL guys can't only adjust your devices to the given surrounding frequency-
situation in your home-country or test-garden, if it has to work everywhere,
if you wanna make good business with the rest of the world!

Who cares if in Brazil some long-wave transmitter covers the whole land
and creates powerful reception at a certain frequency everywhere,
if they claim the LRL works all over the world while its fixed to that frequency?!


Perhaps some receiver will work that is able to use all the EM-field-energy
from the frequencies 30-300kHz alltogether, with AGC (auto-gain-control)
so it doesn't overloads if the input becomes to strong.

Otherwise any LRL must contain a seperate transmitter that guarantees
enough eddy-currents creating field-strenght - everywhere!



save the animated gif to watch it, if your browser doesn't repeat it below.

shows that the ahead-orientated ferrite-antenna with its 2 different windings already
acts as some sort of directional-receiver.
But this is just a very simple amateurs-solution because the coils are so close together
and they can't detect left right which is absolutly important.

If this LRL stuff should have a chance to work usefully, 4 seperate ferrite-antennas are needed!

6 would be even better, to check out the vertically field strenght.


And its not good to include directly some sort of retro-metal-detector-circuit into
such LRL-device, because even if the MD is fully switched off,
the round, DD or omega coil of it will suck away or disturbs the weak long-wave EM-fields.


But highest priority has a useful signal output !!!

With one stupid LED or a beeper this doesn't work and sweeping the coil into
find direction also doesn't work because it would be like turning an AM-radio
away from its (best) reception position!

It depend on wavelength. As shorter wavelength are, so closer to each other can be placed antennas.

In our case it does not depends on wave-lenght but on field-strength,
otherwise long-wave antennas must be placed 100 meters away from each others.

Usually its important how those ferrite-antennas are orientated
(best angle in relation with the vector direction of the wave, as everywhere in
radio-reception) but whats really counts here is the detection of the eddy-currents
and how strong the "transformer cores" = "find-objects" disturbs the balance
of 2 ferrite-antennas in resonance.

In other words:
The "interaction circle result" of radio energy, find and closer ferrite coil #1 is different
as those of radio energy, find an more far away ferrite coil #2.
This is real induction balance because the transmitter is somewhere else.



btw. perhaps the found radio transmitter at the Mineoro test wasn't some evil trick
but indeed just a method for going shure that this detector outputs useful results
at a foreign country where the surrounding long-wave-situation is unknown.
But then of course they must have openly shown and placed it somewhere
so all the involved persons would have known already before what's going on -
AND - Mineoro must offer in such case all the time such a supportive transmitters
for orders from other countries - what this suspicious company for shure is not doing!

Everything else would be cheating on the customers or fraud and we would condemn it!
