I don't know either about the ferrite antenna, my Alonso replica is on the shelf for years collecting dust, was just a waste of time. I just bought a Minelab Metal Detector and have fun with it. At this time I think all this PDK stuff won't work anymore since WiFi, mobile phones, etc. are everywhere and will interfere with the PDK, PD, ...

Thank you Daniel.

Interfierence is not a problem with a well designed antenna input though.

Are there any photos in general from the original pd?


Thank you
Hi Jeg.
The ferrite is aligned with the outside of the omega.
I have all infos but now i am busy. I believe at end of October to have free time.

About the device, i have some spare time and so i am thinking to experiment with that. I ll start by using only the ferrite section and a modulated transmitter. We ll see.

So many people wants to construct the Alonso's PD, but it is not the best lrl.
It is possible to construct one lrl much more simple than Alonso's, more sensitive, more stable and more easy to adjust it. Where is the problem then???? problem is that so many years every electronic or hobbyist reads everything about Alonso's pistol but nothing for other solutions or conditions that must have a lrl.
And nobody (except only few members) are able to construct this lrl because they don't know every secret about it. They knows only what the owner decided to show ....

Do the change. Boost amplification withouth self oscillation.

Inside the circle of coil is vedry very difficult to null the signal. If u have n't a very good null then u have saturation on receiver.... This is the big problem.

Are you talking about zeroing the Tx signal relative to the Rx coils of the metal detector?
