Sounds like you have a EMI problem. Electrical Magnetic Interference.

Or RFI Radio Freq Interference.

If you take it out side away from 60hz does it still do the same?

Try turning down the Preamp on the Receive side a bit.

Do you have any long wires on the Rx sections?

Touching the wand and it responding tells me you have serious EMI around your shop.

Sorry this is a English Speaking Forum only.

Please only respond in English!

I feel soft today so here you are!

Parece que tienes un problema de EMI. Interferencia eléctrica.

Radio Frecuencia Interferencia o RFI.

Si se toma fuera del lado alejado de 60hz ¿todavía lo mismo?

Intente bajar el preamplificador en el lado de recepción un poco.

¿Tiene algún largos cables en las secciones de Rx?

Al tocar la pared y me dice que usted tiene serios responder EMI alrededor de su tienda.

Thanks for you reply

Where can come from the EMI?

how can i turning down the Preamp ?

RX cable length is the same as the TX

If you just connect the TX coil is the same problem, watch this video:

Power lines, Florescent bulbs, you name it.

Try adjusting R36.

Did you use sockets for the Chips?

Starting at the front end, pull one chip at a time to see if the problem goes away.

If it does, the problem should be from that chip back.

I follow your Post on Geo Tech and there telling you pretty much the same.

Without Proper Test equipment like a scope, this is the only way to do it.

Hi homefire, I put the post in 2 places because I am desperate to get it to work.

Since I have no scope I made some measurements with the multimeter in the coils.

RX 25.8 ohms --- 107 laps

TX 23.8 ohms --- 98 laps

I also measured on pin 4 of the LM393, where in theory there-5v and 6v I have, actually, it may be that the problem???
