The first impressions - great place, unknown to many t.hunters. A lot of good signals with your phantom lrl , FrancoItaly. I like night prospecting and digging in full darkness. Lot of Roman bricks have dig out. Very probably ancient roman town or roman military fortress. The great number of lrl signals on some places 3 led diodes has full lit. With maximum dc amplification compass effect imminent. Also both lrl sensitive to ground with almost maximum amplification but without the compass effect.

Need further lowering sensitivity for normal prospecting. Dig up to 80cm with vlf DD sonde 38 cm , no usable signal. Also small 10 inch PI sonde not usable signal. Estimated target depth more than 1,5 meter in soil. The strong signal disappeared when the top of stylus-whip antenna was over tha possible target. Conclusion is very deep target, 3 led lit at full brightness. Scan area about 50cm in diameter with the hole of same size.

Francoitaly any idea how to G.E.B your phantom lrl - quartz version for fully rejecting highly mineralised Roman soil ?

How to estimate probably depth of gold and silver targets ?

ps. both lrl high tech tunned only for gold and silver coins at test polygon 30 cm deep before any prospecting job.

ps.1 posted alonso gold leaf cavity resonantor at 11hz because need additional modification of your lrl with some useful type of discrimination noble targerts.

ps.2 i have forgot to say about 10-12 UFOs tracked my activity from the safe distance. Maybe your lrl on some unknown ways ineract with alien hi-tech equipment in their space ships ? 10-12 UFOs all have been highly orange illuminated. In my oppinion they are very big space cruisers. All till the one flew without any hearing noise. I bet in 1 kg gold all ships have full invisibility to human eyes spectrum.

ps.3 What do you think about attaching alonso golden leaf ionic chamber to your lrl and pulsing the leaf with estimated telluric underground Tesla waves about 11 times in second ? Alonso's magnetic copper loop antenna is very interesting to be attached at front end input of your lrls, both versions - pll and quartz instead stylus-ship antenna and tunned for resonance in 120-140mhz band.

Francoitaly, i think we need some kind of antenna / coil stimulator for your passive rf sniffer, like it was for example in form of alonso's golden leaf ionic chamber and which is also implemented in Mineoro 2000 special series lrls.


for example

here instead not useful ionization chamber draw Alonso's pulsed golden leaf resonant cavity chamber. it is similar like RF resonant cavity thruster - NASA microwave cavity engine. In Alonso's case instead RF, resonator use Tesla telluric waves which produce surface acoustic waves of golden leaf resonator. i think dimesnions are very important for correct functioning lrl device.


remember that australian rangertell lrl use same very low frequency pulsing frontend rangertell antenna using close proxmity inductive coupling from texas instruments digital calculator with square wave pulses. Pulsing with sqw has a lot harmonics and very possible some of 11hz overtones hit the proper combination for saw waves sync.


Regards from ancient Roman fortress - probably with lot of golden coins.

As I have already said I do not have much experience in research so I do not know if you can evaluate the depth of the buried metal. The fact that the signal disappears on the vertical of the target is normal. I have never experienced a disturbance of the ground but rather a sky effect, ie the appearance of a signal by lowering or raising the lrl. However this effect is connected to the compass effect and disappear together by lowering the gain. As for the coil stimulator my first functioning lrl in practice it was a PI, a 60Khz pulse oscillator excited a resonant coil at about 5Mhz, the receiving coil, arranged perpendicularly to reduce the signal. The signal of the receiving coil and that of the antenna (V-shaped) were mixed in a toroidal transformer and sent to amplifier and sampler stages. The transmitter coil was the same as the oscillator at 8Mhz in my last lrl but according to me it was not useful for operation, or at least it is more complicated to realize and to fine-tune. We can say that the first exemplar of lrl built by Alonzo was a commercial metal detector modified with the addition of a ferrite coil, which was the receiving antenna. In my opinion, all lrls are of a passive type and no signal is transmitted, there may be some kind of filter to highlight gold but I have doubts about their effectiveness.
