Hi.
Today is a good day but how to try the LRL??
Yesterday i replaced the 9V batteries with a pack of 4x1.2V rechargeable and o pcb with TL497A. All are OK but the LRL don't detect the electromagnetic field at Lab
. Problem??? the oscillator of TL497!!!
Pulses of it overload the input so it is not able to detect anything. Today i will try with a shielding coil for TL497 and if no results i will replace it again with 9V batteries.
Regards
