Lrl from Italy

[FrancoItaly]

Hi enjoykin4,
Very interesting but in my lrl (quartz version) there is only a 8Mhz oscillator (not tunable) and a tank circuit L1C1 (in the range 100Mhz-150Mhz). With CD4046 version we can measure the phase shift with no target and with target. With a more elaborate version of this lrl we can measure simultaneously the variations in amplitude and phase.I created this to get a kind of discrimination between gold and other metals but with poor results. Scalar waves could still explain the operation of the LRL. I'm glad you've tested positive my LRL, can you tell me some details?
Best regards

Hi Franco.
I have construct the xtal version (again) so to put it inside an new LRL that i have build this month but has some problems.
1. when i touch the antenna led don't turns on, but if it is on then it turns off.
2. with full sensitivity don't works as compass....
3. don't detects a gold buried coin but other lrl detects it.
Signal at collector of TR2 is 10mv p-p, at TR3 =110mv and at TR4 is 1.05V.


Any idea???

Regards

Hi Geo,
1. It may be that it works in reverse way, try change input+ and input- at the first operational (LM35
2. As I said in other thread If there isn't compass effect with max gain it is necessary to increase the gain of the LM358. With the gain at most there must be the compass effect, so you have to decrease until it disappears.
3. The use of the oscilloscope may change the behavior of the amplifier stages, it is best to measure the DC voltage of the emitter of TR5 which must be in the range 1-6V, also the DC voltages of the collectors of all the transistors (TR2-TR3-TR4) must be in the range 3-5V.

i built all version of your lrl , and lot of prototype of 8 mhz stage with modification , we can realise two receiver . magnetic and static

[FrancoItaly]

do you mean magnetic receiver for my lrl?

[abdou2014]

yes !

[FrancoItaly]

A magnetic receiver requires a magnetic antenna which can be a coil wound in the air or a ferrite antenna. In my lrl there is only an electric antenna, can you explain better?

[abdou2014]

of course i tried it with different antennas , and it can detect small transmiter from 3 meters

[FrancoItaly]

But it works as LRL?

[abdou2014]

I think. but i have not yet detected gold with it , what is the final step for you , can you help me ?

[Geo]

of course i tried it with different antennas , and it can detect small transmiter from 3 meters

So it is a radio... but are not all radios lrls.
Maybe a radio to catch a signal from a buried object but generally most radios don't have this ability. Make a test field with a buried object and try to locate it after some months. All the other are only to doing chat.....

Thanks Mr Geo .

Actually, according to professor Dr.Gennadiy Vasilevich Nikolaev - magnetic fields does not exist in nature (nor Vector - nor Scalar magnetic fields).

There are exist only GRADIENT ELECTRIC FIELDS which were caused by DELAYED POTENTIALS and deformation of COULOMB FILED at the movement of charges.

what is maximum detection distance and maximum detection depth of yours PLL4046 LRL ??
20 - 30 meters or more ?? about depth can detect big golden deposite 3-5 meters in soil ??

does your PLL4046 LRL detect "PHENOMENN" induced only by gold and silver or all other noble and non-noble metals in the soil ??

Hi enjoykin4,
I tested the 4046 lrl in the same test field of quartz lrl and I found that they had the same performance and I did not other tests in a real field. AS I said to Geo to achieve better performance with maximun gain you must have the compass effect, if it's not the case you have to increase the gain of LM358.
