Why put a 50Hz filter when this signal is not there? If you use the lrl in a place where there are high voltage power lines it does not work.

Hello Franco. Years ago... when you built remote sensing based on a separate transmitter and receiver... I corresponded with you privately... after studying your new circuit... its performance is clear. And how it detects the target...many people do not know the philosophy of revealing the phenomenon and I think it is better to keep it secret. |

I don't remember exactly what you're referring to, but in my opinion even if there is a transmitter it still works as a passive receiver and not as a radar, in fact if that were the case the transmitted signal should reach the buried metal and then come back.
