Real clone Alonso-PD

[behnamvp]

good day

Here are a few measurements. hope to be useful for who interested to study Alonso-andreas PD.
Please notice that written values are all approx. values depends on ?measurement device?, ?how to wind coils? and ?what size of wire used to?.
Anyway, in any condition, I do not think the result will be out of the ?given range?.
It seems presence of ? UHF ? signal is vital for device to work as a long range gold detector and Just by making and assembling, device just works such as normal metal detector and not as LRL.

Once again: the UHF influences is taken from a video by Mr.andreas Christi, which is about ? pocket-size remote gold detector ?. This video available on youtube at his channel.

Here I must say: many thanks to Mr.andreas Christi from Greece also special thanks to Daniel for wiring diagram.

Here are a few pictures:

Adreas new pocket LRL

PGF170 Gold Detector by Andreas...

this LRL is working with IR/UV LEDs ???

I see video now, its other system LRL

Morgan, some questions about your famous original Alonso PD.
The PD detects massive metal targets (like cars) from a medium distance? say 3-5 meters.
Also when it finds a good old target, if you hold it stationary, has signal?

thanks Morgan.
so in conclusion ,the Alonso PD is no-motion and detects very big metal sheets etc.
I'm asking this because I had this "strange detection distance" with the ToTem (tuned in limits as you say).

those who manage to calibrate at 66khz will have success

Good day
66 KHZ receiver or transmitter?
if you notice to values given and written on the schema, by calculation other frequencies
will appear. practically as i measured by oscilloscope, not much difference in calculation
and in performance.
something is missing in alonso-andreas PD. there must be an "extra factor" which has crucial
influence that PD need it to work and detect even fresh gold under ground.





here you can see 181 khz which measured by oscilloscope.my device
