Hi All,
Here's my humble opinion, based solely on my LRL (with others like Alonzo PD or mineoro clone have not been successful). First of all I think that none LRL can only reveal the phenomenon and be completely insensitive to any other electromagnetic noise or static electricity.
1. Schematics. Is there any complete scheme of a LRL by anyone and whose proper operation is confirmed by most people? I agree that sometimes it is enough to change the value of some component to operate the LRL.
2. Coils. 3. Coils housing. 4. Box -case. As I said I refer to my LRL, the coil has 2 or 3 turns air core and it's no critic, the box is made of plastic and is shielded with aluminum foil (in some specimens rather I did not shield but the operation will change little ).
8. Signal from your hands etc. True bringing the hand to the LRL there is a change and holding the LRL with two hands there is an increase in sensitivity (the handle is also screen), though once challenged the behavior is normal. But despite this, the LRL works perfectly. My LRL has a stylus antenna and obviously it can not be shielded.
9. Ground and sky effect. True to eliminate ground and sky effect is necessary to adjust the total amplification.
This is not to say that Andreas is wrong, I just say it's not true for every LRL.
Best Regards
