thanks dear nic
for frequency between 55 to 155 KHz
you think this frequency range is good?

55 to 115 khz is the Good for me
Because I experiment that

For other I don't know

hi dear nic


what is the 3 pin?
if i use variable cap i must remove cx??
thanks

Is for charger connector

Cx = 470nf

[jocelito]

Hello Nicolas capacitor cx this as 470N in another scheme that appears to have 470pf which is right?

Hi jocelito

Oh sorry you are right the best is 470pF the 470nF is the wrong sorry again..

and the other LC is 6.8nF

Hi See the morgan PDK you can understand

http://www.longrangelocators.com/for...ad.php?t=18145

To not enter the depth of the devices
It operates on the principle of measuring the signals emerging from the ground trove

Whether at a depth of 20 cm or 20 meters
It can range in some burials to 100 meters

Bank apparently do not know how to operate these devices

If you want to buy a device from the My Devices hello

http://kaisar-detectors.com/
Or sophisticated equipment hello

http://www.alphageofisica.com.br/mdl/quarryman.htm

Laser LRL with 3D ...long range to 1200m

Good luck my dear

[GOLDEN LILLY]

Hi Nicolas,

Please show the complete schematic and the parts list of this project. It is also suggested to better include instructions on how to tune this lrl to the desired target.


Regards....

This treasure was found by a married couple who were out walking the dog on their property. They saw a can sticking out of the ground under a tree.

Hello Nicolas, I would also print the pictures of the base to be able to stampare.tanks

Hi dear I have put all
you can find it here in topic

Hi Nicolas

Why 55-105khz ,
your 50-60 khz
80-100khz
also interesting for me.
I though you are from hungary?

frequencies between 50-60 are just british 52 57.4 60 and turkish 53.4 channels
and 80-100 just one british 82.80 and loranc 90-110

which band is better according to your field tests
regards
okantex

[okantex]

and, there is no varicap or trimmer in Nano level in practically.

since capacitor side of desing has to be fixed because of short varying range. only option to change pfrequency is L inductance. it is also mechanical structure which has to be fix naturally.

only and last option is using using rotary switch and having diffrent caps for each frequency . but practically we also can not have capacitors that we may need.
for exp. we can find 8n2 but if the result of calculation is 8n3 ,what can we do ? can you add 300p parallel to obtain exact frequency? not sure? need eelectronic experts ideas

[okantex]

btw , I am in the game , I bought components yesterday , but I can promise ,when will it be ready for the tests

ıs there anybody else ,who has constructed or going to construct this project

Hi Okantex

Here I put your advice for LORAN -C

http://en.wikipedia.org/wiki/Loran_C

http://en.wikipedia.org/wiki/Low_frequency

http://en.wikipedia.org/wiki/Radio_navigation

For Germany is 77.5khz

Standard time signals






In the frequency range 40 kHz–80 kHz, there are several standard time and frequency stations, such as

• JJY in Japan (40 kHz and 60 kHz)
• MSF in Anthorn, England (60 kHz)
• WWVB in Fort Collins, Colorado, US (60 kHz)
• DCF77 in Mainflingen near Frankfurt am Main, Germany (77.5 kHz)
• HBG in Prangins, Switzerland (75 kHz) (closed down on 1 January 2012)
• BPC in Shangqiu, China (68.5 kHz)

You are great to understand that

Hi Nicolas

i build your project

when i turn it on the red led turning on and i dont have any sound in speaker and led2 is off

i play with RV1 and RV2 but nothing happening

i want to test it but i dont know how

am i need a transmitter for it?

witch one you Offer?

thanks

[Nicolas]

So nice saber if you build it.

1-/ The led Red is for Bettery try the RV1 to calibrate your voltage for battery

2-/ The led Green is for detection target you need tray it in field test metal buried or in location you think exist Treasure. and try with RV2 for Gain

3-/ This PDK not work for fresh metal only for buried metal since times.

4-/ You can first choice your frequency to work. you can tell me your country I advice you the frequency

5-/ Not need transmitter my friend

you can add me in skype for help

I wish you good work

[saber]

thanks Nicolas for your reply

I'm from iran (the hidden Treasures country)

please help me for choice my frequency (how can i change frequency?)

thanks

Find fix your reception frequency between 24.75KHz and 44.03 KHz and try it in your country
and give me your comments and test

you can use this to know your value for coil and capacitor

hi Nicolas

thanks for your reply

im a amateur.i'll use 0.6mm wire and 6n2 capacitor for cx . is this true?

if its wrong please help me for value my coil and capacitor

Hi dear there is 620 pf not 6.2nf

0.00062uf = 620 pF
0.062 uf = 6.2nF

but you can use it is good for 25khz

WHAT IS DEPTH OF PDK???

DO YOU MR NICOLA SHARE PART LIST???
I AM WAITING TO ANSWER
THANKS

Hi dear about part list you find that here in Topic

and about calibration and other question you need read here in forum about all PDK's project. Before you built the LRL or PDK or others devices for understand

[saber]

hi Nicolas

thanks a lot for your helps

i use bc557 substitute for bc556 transistor and i use a buzzer

is it made problem?

when i turn rv1 the red led is lighting (is this true? how can i calibration?)

in your schematic you write %17 for RV1, is it for calibration?
