I used the CA3130 for the input stage in a low frequency and very high impedance version, but it proved to be extremely sensitive to walls, trees and the ground itself, therefore practically unusable and this excludes the possibility in some way to use the measurement of ions to reveal the "phenomenon". Furthermore, the first working lrl I made was in practice a pulse induction MD with a transmitting coil (about 10cm diameter), a receiving coil (a single turn) perpendicular to the transmitting coil and an input stage formed by a toroidal ferrite with three windings, one connected to the antenna (V-shaped), one connected to the receiving coil and one connected to the input stage. The three windings were tuned to the operating frequency of the transmitter coil (which was not damped as in the usual MDs). The oscillation frequency of the MD was 60Khz but that at the ends of the transmitter coil were not damped oscillations of about 5Mhz. In this type of lrl I can exclude that there was somehow the frequency of about 100Mhz as in my last lrl.

Thank you FrancoItaly
Very interesting experiments you did, and very smart configuration of your modified pulse induction MD wit non dumped transmitting coil.
maybe i need to start exactly from that configuration. Only i want to know, does this modified PI-LRL has ability to discriminate (classify targets) according to Esteban Cabrera Grinok, between gold, silver, copper, aluminium and ferrous targets ?
If your answer is positive, i think i would like start from exactly your configuration and listen your next suggestions and advices.
I think i can do it, but need some time to check up new hardware at real terrains with real ancient targets.
My logic is so simple. Why to rediscover something you already did and it work good. I need a real working LRL for me and my best friend, not for comercial purposes, not for glory, not for grants etc.etc. Only one good working LRL any possible type which tuned work good with GOLD, SILVER classifier for prospecting with my friend Bojan, mostly ancient roman's terrains here at South Serbia. I need to get away from mountain where i am currently living. Geo has some photos of my old house in highlands. I need to come back to city again and very probably get away from Serbia, maybe Greece, maybe Italy, maybe Brazil. Who knows ?
Best wishes and regards
from the mountain
