Hi Dragan

Nothing special.
No stimulator only one RFsnifer with 55 DB gain and one magnetis detector with 80db gain. Every detector has its own antenna. It needs null between antennas but not so big problem as at Alonso's PD.

Regards

Hi Geo.

Why your magnetic detector must have almost 18000 times amplification ? Why not 100dB - 100 000 times? Maybe it is upper threshold for stabile work ?

Thera are many new very high band OP amps with open loop unity gain beyond GHz. Why don't use some of them as input frontend?

Regards
Dragan

It is very simple!!!! because i had the pcb with the 2 ICs with total gain 85db at 100+ Mhz.
The problem is that i can't give full gain because it beeps

Hi Geo.
It looks good.... but.... but... I'm sure same as your previous habits have no decision to help other people here to make this or any other device like this....
So,.... so... what's advantage of presenting it? it makes no sense.
you know most of times that I remember you, think about your main purpose of this behavior?
Anyway I wish best success and results for you.

Hi Panos... how are you???

Where did you find my lrl??? i don't remember when i gave it to you.
With it a friend at peloponisos found many objects.
The funny thing of the story is that i never found something with it, only the other operators!!:
