jjaja ok franco, i see fix these, regards

hi franco
VU meters using
I want to be linked to lrl quartz version
Where you can connect and link IC1A , IC1B , IC2A or IC2B

[brs]

TR1 5V
TR2 0V
TR3 1,1V
TR4 1,2V
TR5 4,57V
PIN 1 IC1 0, 800V and
Increases with voltage lighting gradually
---------------------
PIN 7 IC1 10.58V
And IC2 10.63V
With the lighting voltage is reduced without gradually to 1v

[FrancoItaly]

First unplug the oscillator disconneecting C2, the voltage of TR2-TR3-TR4 collectors have to be in the range 3 - 5V, to increase the collector voltage should increase the resistance between collector and base and vice versa.
For TR5 emitter 4.57V is ok. You can connect the VU meter at PIN 1 of IC1 with the calculated resistance suitable for 11 volt full scale. IC2 is not necessary and you can use IC1B for buzzer.

thank you Mr franco

hi franco
bc183c Alternative bc550c

[FrancoItaly]

Yes it's ok

[darkman]

any Professional one here try any thing with new sensor stage ?

[FrancoItaly]

The new sensor stage, self oscillation type, it's very critical and unstable and I do not recommend. Instead I have modified the Lrl with CD4046 and I lowered the frequency to about 59 Khz (gold frequency?) It's very stable but I have not tested on real field. I used a ferrite coil with 200 turns (1.8 mH). If the lrl is ok on the field I will post the circuit diagram.

[FrancoItaly]

I just got back from the test field , unfortunately no signal from silver coins and a gold bracelet buried for over a year, so my ferrite coil LRL is not working.

Thank Franco
If quartz device best

[brs]

Battery and handle hand must be far away from the circle PCB

Bad news but no problem, you have so many workable versions.
Hello Franko, continue your fantastic work.

[FrancoItaly]

Hi Geo,
Thanks for the compliments, there is still a chance for the ferrite coil LRL, in fact I had no connected the stylus antenna, now I have done but I can not go in the test field, too hot and too many mosquitoes.
Best Regards

Hi franco , how are you ?
That is bad news .

[FrancoItaly]

I'm fine but I will return soon to Switzerland and will not return until a few months. The tests will be for autumn.
Regards

hello lrl builders brothers here i show yours my new lrl prototipe 2015 this is in aware of tries and news possible implementations i gave special thanks to my friend FrancoItaly for iniciate us in these actual projects a embrace for you and for all, gun semms succesfull here i need try in fields but havent gold buried but 20 coper coins https://www.youtube.com/watch?v=5RDR...ature=youtu.be

[detectoman]

a strange lrl whit capability for detect all class metal near the antens also static plastic

Mr. Franco
Do the phenomenon(Electromagnetic energy) of all-metal buried until flattened iron manufactured phenomenon

[FrancoItaly]

I must say that not much is known of the phenomenon, but I'm sure the iron is not detected, any form has.

[brs]

Thank Franco
worked on the assembly of a new quartz device and the work I have 2 silver ring at a depth of 40 cm was discovered phenomenon of almost antenna Pen distance 1.5 meter and be prompt on the place also discovered from the north to the south only

[FrancoItaly]

You say that you have detected 2 silver ring at 1.5 meters in north south direction?

[brs]

Yes almost 1.5 meters depth of 40 cm length of 9 months and buried detected from north to south and only weak from east to west
