the power supply is 18 V (2 X 9V battery) the IC is 7812 that, yes, requires more than 15V. Usually for low battery voltage I fixed 16V then an operating range from 18V (full charge) to 16V.

Hi Walkman,
Have you already tried the LRL in the field?

Bravo walkman!
Congratulations and thank you for PCB!
Now it's OK!
Write about your test results.
Thanks in advance!

Dear sneshko

Stll selling GPR for 20,000 bucks ??



You must be one of the Reachest GOLD HUNTERS (lot of Golden coins) in Serbia if you have such kind od proffesional equipment in your prospecting menu!!

Would you like to share with us your personal experience in work with this very expensive professional equipment ?? I am interesting in real detection depth and precision of underground mapping software at real hard soil - hot rocks and highly mineralized ground !!


ps:

Dear signore Franco !!

What do you think your LRL crystal version can work at 10GHZ - 12GHz ??



No it is not a joke Franco. I have plans to modify one old LNB (low noise block) from my old satellite antenna 1.8m dish - make simple feedhorn antenna at 10Ghz-12Ghz and use his very temperature stable and compensated VXO with integrated pin diodes amplitude detector at output. For signalization like you did - 10 highly bright led diodes in VU meter row.

Input oscilating circuit can be easy tunned at higher or lower freq. using integrated dielectric resonators for strip line waveguides matching. Also bandwidth can be adjusted at some range with tunnable short circuited stubs for both horizontal and vertical polarizations.

Maybe this .... 10GHZ-12GHZ version is secret to miles away long range distances ??
Who knows ????


Ps: Also i wish to hear your professional oppinion and advice about Russian long range locator IGA-1. Would you like to analyse schematics and give your prfessional sugestions about this device ?? It is not so hurry to me - so when you find some time will be fine to hear from your about behaviour of two low drif PID regulator loops of IGA-1.

Correct name from Russian is Geophysics Anomaly Sensor !!



Check this Jura's site

Hi enjoykin4,
I do not know if such high frequencies can be operated, without a doubt in the sky there are many transmitters that can "excite" the phenomenon, but would not know how to adapt my LRL at these frequencies, perhaps it would be better to study a new circuit. As regards the long range locator IGA-1 at first glance it seems a selective amplifier that can work on different frequencies but I have problems with the Russian language, however it seems a passive receiver as the Zahori.

Best Regards

hi franco
Are minerals buried a meter deep and a half Ahumicr logic far from the transmitter towers and communication do you need with a passive receiver transmitter stimulates buried metals and if it was necessary to send Is there a circle

You mean a kind of radar? Transmit on one frequency and receive on another frequency?

If even.
At least Zahory iz able to detect something (static charge), not so IGA-1 which is pure waste box.

1- - According to the scheme Franco Italy, the buzzer is connected to the pin OUT1 IC B are not to pin 2 to IC A

2--Look this photo there is a track to add

Dear Nicolas!
Thank you for Radiation Meter!
Coming strange time ... who knows? Perhaps all of us this device will be necessary...
Can you put it on forums for a free download and Programmed controller ATmega88PA-PU?
Regards!

Hello Franco !!

Signore read how this ********************************************** AGAINST HIGH-END RUSSIAN LRL DETECTOR IGA-1. {75meter detection distance for underground water veins is very nice result for LRL !!)

Hi dear enjoykin4.

Please need respect for all other members see this the third insult and not respect. i not have what do here go elsewhere or stay and speak with much respect we are all here for knowledge please and not be racist stay tolerant.

Because i see this behavior for person ignorant lacking knowledge or awareness in general; uneducated or unsophisticated.
