Oscillator works perfectly

[FrancoItaly]

Well, what is the purpose of this oscillator?

[shahrayar]

To increase the earning
The internal oscillation will be in MHz
Increase the sensitivity until you discover this phenomenon from the antenna

Is this system more sensitive than my original lrl? when the sensitivity is such that the compass effect appears, well this means that it is useless to further increase the gain. As I said before the inside oscillator only serves to create a mixer with the phenomenon. It serves to make sure there is always a stable signal at the sensor stage output, even in the absence of the phenomenon.

[shahrayar]

My dear Franco, it is the original I made it before in this way, but due to the lack of capabilities to measure the signal, I used only simulations, and it turns out that most of these programs are a hoax
But with the new simulation program, I discovered my mistakes
Perhaps you studied in universities and schools, but I did not study in universities and schools, and you know your system from me, I am just learning

Now I understand that we do not need an oscillator, we need a gold phenomenon in order to activate the oscillator
The emulator program is : SIRCUITMAKER2000

I too have not studied electronics at school like you, but I have over 50 years of experience and I studied on my own. I use multisim but not to check the functioning of a circuit but to find the appropriate values, for example, related to a certain frequency.

[shahrayar]

Since you were twenty and you have been learning, then you are a teacher

[shahrayar]

Now that you have modified it, it is affected back by hand
For example, when rounded to the TV, the three lights are on, and when the hand is rounded 30 cm away, the lights start to turn off

As I said before, all tests with TV or mobile phones, however inside a house, are worthless. The only test, to be carried out if possible outdoors, is to touch the antenna and (after adjusting the threshold to have the first LED just lit) check that the LED turns off. This guarantees that all the electronic part of the lrl works correctly. Obviously the final test is in the field.

[shahrayar]

Thank you dear Franco
Now it looks good to me. In the Roman square near my house, I will try to see the result. This Roman square is rich in treasures

if anyone wants to test his Lrl which he made himself, i have places where the rocks are big and there are engraved signs on them,such as having a cross sign on the rock, snake, turtle circles, and arrows these signs are old civilizations and their meaning treasure signs my problem is i dont have lrl check site with signs of old civilization if anyone wants to see signs i can send a video clip from that place to every one ho is interested for this place

signal direction east of franco. Range 700-800mt

I don't think my lrl has a range of more than 20/30 meters (as I think most of the others). Are you sure you don't have a compass effect? If the signal remains constant going in that direction it is almost certainly this effect.

[okantex]

But walkman is saying..direction is east.
Not north-south direction
How can it be compass effect
Can bobins' direction have effect

If the amplification of the lrl is too large, in addition to the compass effect there is also the sky effect, i.e. lowering or raising the lrl you have a signal, the two effects can be combined making it impossible to use. The lrl is a directional instrument, the maximum sensitivity is proceeding from north to south, the minimum is proceeding from south to north and proceeding from east to west and vice versa the sensitivity is medium. Furthermore, approaching the target, the signal increases but cancels right on the vertical where the target is buried. I find it difficult to believe that a target at 500 m can influence my lrl, to be true it should behave as described above, i.e. approaching the target (i.e. at 500m) the signal first weak and then increasingly strong until it decreases and cancels over the target (500m ahead). My lrl like almost all the others ultimately reveals an electrical or electromagnetic signal and therefore is subject to many disturbances.

[okantex]

So, solution is easy
Another test with same adjustment
But without any target . At another place
İf there wont be change on leds...on east west
Then on south north. Directions.
Then on nort south , by increasing sensitivity if he will see compass effect and lose it by rotating to east south..voila..
Walkman will be right about his claim.
Am l right?

Yes

Hi Franco ,

I need some advises
I made circuit.. improved anttenna + 8mhz +display 3led +lm3919
I am detaching potansiometer middle leg..(4.k7) , to disable antenna input ..

buzzer is working..... circuit is single side pcb..but placed on aluminium case...and also ground ed to aluminium case. so , in a way it should act as double layer..
signal is strong..is it self osilation.. even playing with display stage pots ,it does not change

pcb paths seems good. I could not see any short cuts..
I used metal film resistors..ceramic condansators ,bc183c ,8mhz crystal

take care of yourself , stay at home.. stay away from corona risk factors.
wish good luck to all LRL family.
Okantex

[okantex]

btw , after reading helps...I disconnect 4k7 pot of amplifier stage.. means antenna input is cut.
buzzer was active
so , I also disconnect cristal..but buzzer is still active
entrance of IC1A = out point of sensor stage = is 8,25V
is not this too much... changing 560p to 470 p ..will this help...I feel not...

[FrancoItaly]

Thanks for the good wishes, I certainly do not leave home, also because I am in the risk category (over 65 years of age). 8.5V at the sensor stage output is too high, it means that there is self oscillation. I recommend using a separate pcb for the sensor stage. Try using BC ... B type transistors with less gain, replacing one at a time. The important thing is to set up the sensor stage before connecting the amplifier antenna and keeping the original connections.

[okantex]

no antenna
no cristal..
what can cause osilation? just resistors and condansators
btw .. I placed the pcb abovealuminyum .and made ground connection ..now 2.7V first led is brillient.. second and 3th are blinking

do you still advise to replace transistors

[FrancoItaly]

Yes, try replacing the transistors one at a time. Yes, try replacing the transistors one at a time. Of course C9 must be connected to the antenna during calibration, this is to restore the original conditions without the amplifier antenna.

[okantex]

sorry , I did not understand.
on antenna amplifier addition.. C9 is connected to 4k7 pot's middle leg. I already disconnect it to disconnect antenna from sensor stage..
after seeing Null ( 0 V ) on sensor stage output ( on IC1A 's pin 3) , I will connect antenna.

what do you mean by calibration.. the calibration on field ?
cause your sentence " this is to restore the original conditions without the amplifier antenna." I am confused.

because during calibration of sensor stage.. you already write in HELPs file..to disconnect antenna.
if I connect C9 to Pots middle leg.. and just detach the telescopic antenna.. then I may receive field effects from bobbins.? but on the otherhand it may be better to calibrate the pcb with this disturbances too.

so , what should I do step by step

1. connect pot to C9
2. disconnect just telescopic antenna
3. decrease value of C13 and C14 , 560P to 470P
or 3th start replacing transistors

[FrancoItaly]

The initial calibration is done in the laboratory, therefore C9 is connected to the stylus antenna, the sensor stage output must always be present (even without phenomenon) and the optimal value is between 4 and 6V, to achieve this follow my helps .txt. When you have obtained the required values, you can connect the antenna amplifier, but it would be better to first try the original version in the field.
