Modifying old LRLs

[Geo]

Hi.
For this winter there are n't new projcts... i have construct a lot of lrls.
So i decided to modify some of them.
I started with the Andy's Flind MFD.
The main problem of this project is that it oscillates when buzer is near to coil and u try to give more sensitivity.
I found the solution and now i can give more... more gain, so i believe that its a super lrl.
Problem is that the weather is not good to try it. Later....
Also i connected a FM radio with TDA7000 so to have a "second" EMF detector.
