[goldfinder]

Hi Esteban,
Bravo amigo! You have finally learned not to respond to the nay sayers and focus on your very constructive ideas to help us out on this LRL detection.

Here are some questions regarding your circuit:
1. You have tape recorder but it looks to me like all you need is a tape player without the record feature ???

2. Please provide more details of the pickup coil design. Such as size, magnet size, number of turn of what size wire.

3. Please provide more details of the "detection" circuit on the output of the detector.

4. Where is the oscillator - not obvious on what you mean. ???


God Bless you and many thanks for your patience and help.
