Watch "My new FrancoItaly LRL" where there is the full realization of Sneshko: "http://www.longrangelocators.com/forums/showthread.php?t=19076"
that did a really good job. However the important thing is to try to avoid the auto-oscillations, as TR2, TR3 and TR4 are a high gain stage, it's better a pcb not too small, maybe double-sided with one side connected to ground.

Hello Franco in advance thank you very much, only i commented that I interesting to do your project but with PCBs that you made and I would like to ask if you can put an image of the face below the sensor (8 mhz) to see how this your connection to ground you say, and image how you connected the antenna and the antenna as it should be because I have a television antenna but do not know if this type of antenna used for the project or only i have to use only the RF radio type with metal tip?.
I say I want to see pictures of your PCB because I think they are better such as do the Teacher Alonso.
It's something I do not understand but that making the PCB's so as make Alonso, the LRL work well.
You would have some difficulty in putting images of your PCBs? when you come back to Italy? if you have your lrl in Italy.
Also I would ask the inductance of the coil L1 and the diameter of the wire, because I made several coils of different sizes as you said to Nicolas, which should be 10 mm x 10 mm and I can't get the inductance you told to Nicolas that was less than 1 uH, I measure the inductance and only get 1.5 uH minimum and not less with 1 mm wire diameter.
Best Regards.
