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

HI
MR NICOLA HOW ARE YOU?
I M NOT EXPERT IN ELECTRONIC.ONLY I MADE ELECTRONIC KIT.
NOW CAN I CALIBRATION PDK WITH MULTIMETER???
AND OTHER QUESTION:
WHAT IS DEPTH OF PDK???
HOW DISCRIMINATE METAL FREE PDK PROJECT???
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

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?

No not cause neither problem it's good and work

hi Nicolas

Yes that is true my dear is for chek voltage to your battery

use sample: Led light on if you have 9 V Good
led off if you have 6.5 V Low

This need calibration with VR1 to find the exactly Value

the led Green is for target the RV2 is for Gain ans sensitivity

hi Nicolas

those pictures are from your free PDK who i make it

i read all pdk post in this forum but i dont have any idea for calibration this pdk

please if you know some way for calibration (with Multimeter or other way) post it here for me and others

you said this project need calibration but i cant understand why you cant tell us a way for it!!?

i wana test it in field but i cant calibration it by luck!

thank you again for your kindness

[Nicolas]

Wooh my friend really I'm glad to see my project is built by others that can not afford or have a detector for the aur position or the laws of their country.

nice work it's is same at my PDK

Tell me what the milliHenry for your coil? and the value for capacitor in parallel with her?
because you need try with vari capacitor for modify the frequency. Or you can make selector with various capacitors.(look topic PDK morgan to understand ggod)


I see two potentiometer on the box. Listen you need only a single potentiometer 20K for Gain
Parcontre the other is an adjustable normal varistor (Trimer) for the adjustment of voltage and monitoring the state of the battery. example, if the red LED is extinguished to 7 V, set by yourself means you must charge your battery.

I'm waiting your answer to tell you what frequency need to try in Iran.

Look this topic and see all videos. You can calibrate and made it work good and

Hi Nicolas,

very good work.

I enjoy your design. Congratulations.

Hi Nicolas,

very good work.

I enjoy your design. Congratulations.

Thank you my Master you are welcome

[saber]

thanks Nicolas

the milliHenry of my coil is 0.596008 mH and the value for capacitor in parallel with coil is 0.068 uF (682 disk capacitor) and Aantal windingen of coil is 78
ok, ill use a single potentiometer 20K for Gain.

the frequency i try in Iran is 25kHz.

im waiting for your answer

thanks.

Hi saber nice ok

We are agree for the frequency working in Iran is between 25 and 45KHZ Ok

To tune your Pdk for this frequency you need varicapacitor the value is between 22 and 70 nF.

Or use various capacitors with selector for tune this frequency look at detail Morgan
