nelson y shahab, espero les salgan bien sus circuitos, yo he he podido estar mas activo aqui debido a que mi pc se averio y ahora escribo con la de un amigo, una vieja lap top que me dejo hace tiempo, y la verdad no me hallo a trabajar con ella
excusme nelson and shahab for my ausence, i m my own pc whit troubles in litte time i send regular activity in this forum, and build and projects on two box , for okantex please put here the photos of the box in the detector of japan made for citizen japanesse, for my observations on these rare and wonder earlier detector, regards for the forum fiends

i am yesterday in one personal project on one parabolics detector
whit antenna coils tx rx and frecuence aluminum rectance
ok
till tomorrow

Hi detectorman

When will come tomorrow???

[detectoman]

jajajajaa apologies shahab
say me how is going your two box project?
jajajaa in not easy? ok these detectors is ardue work but is big reward in you use
ok send please photos of proto

best regards

I find little error in Chemelec PCB photo. There is the same resistors R10. . Everything else is correct. Greetz

Error Corrected Now.

Cool Garry!

Lol, i must answer some questions here... Sorry! Im 'Lost' in time

Sonar, is that your version of the sevzirfo TR Locator?
I see you made schematics, but I just wanted to ask if you had finished the entire unit and what results you had with it.

No Martin. This TR construction was orginaly designed to VLF detector ALL1 by All/Alexander in Poland but for TR locators is perfect! Now i tried to make TR on Chemelec PCB with small corrections. My TR construction is the same like Alexander design
but i will make this much more stronger. I will test Sevzirfo TR there and finaly change electronic to my own design with
keys on 4066 and many others...
Here You are how make a coils to TR deterctors - All solution. Experience never 'stops'

TR locator

Hi Geo and thanks for your support.
Yes, i decided to build the TR locator, but i need to now a few things:
1.- Replacements or correct value for D1 and D2 (both are marked D311)?
2.- Value for the meter
3.- Correct values for C13, C14, C1, C7, C15, C16 and C3. This are marked number plus mkF, what is mkF?
4.- Need details for both coils
5.- On the modified shematic, there are two diodes marked 1N4150. I don´t have this, so wich diode replacement can do the job?
6.- There are two schematics, the original and a modified version that contains the 1N4150 diodes, wich one are best?
7.- I have the PCB, but i´ll like to know if this is the correct one.
I hope you or anyone can help.
Best regards.
Nelson Santiago-CHILE

Hmmmm...

1 - 1n4148 is good
2 - 200mA -x 0 +x
3 - MkF is in russian uF
4 - 150 w/0.4 on 38cm
5 - look at point 1
6 - again point 1
7 - Chemelec of cor'Z . Greetz Gary!
Thats all help from my side at this moment

5.- On the modified shematic, there are two diodes marked 1N4150. I don´t have this, so wich diode replacement can do the job?

HEY THERE PEOPLE ON THE MARS! what problems you have of! Lk attach

[sonar]

Good solution KT315 - bull in eye!

1n4148 - 100V
1n4150 - 50V

here is my coil


here is my pcb - ( after small burning - someone call to me ) - everything else is good - pheeew!



Greeetz!

[nelson]

Hi Sonar.
Did you build the tr locator that was modified by Gary?
I already made it, but still don´t have enough time to recheck the two coils. In my first attempt i did not made any success, i mean i did´t heard any sound comming from the speaker.
I cheked all frequency points and all were generated correctly. So i belive that the problem must be with the coils. Something very similar to my tesoro Golden Sabre, that did not generate any sound until i got the correct coil setup.
Please any comment will be well welcome.
Regards
Nelson

tow box

I want to build 2 box metal detector.Can anyone help me,providing me some good schematics,or links

thanks!

ye you yes you didnt you try garys t/r locator this is a letest of 2008 .......

Hola mi amigo Detectoman.
Después de varios meses sin contactarnos, como van los projectos?
Ahora estoy retomando el T/R Locator rediseñado por Gary y la verdad es que necesito urgente terminar este projecto, para probarlo en un lugar costero de Chile, donde se dice estarían enterrados tesores dejados por los Españoles.
También he pensado en usar PI de Gary o el Delta Pulse. Obviamente con bobina más grande.
Tienes alguna sugerencia al respecto.
Un abrazo y isculpas al foro por no escribir en ingles, pero ahora estoy algo apurado.
Un abrazo desde Chile.
Atte.

hola nelson

mira: pues yo termine un dos cajas, el witcher de charles rakes, y dificilmente consegui el ic dificil de hallar, a este detector le puse otro circuito transmisor que no es el que mostraba el circuito original' y pues me ha funcionado bien, no tiene mucha penetracion, quizas un poco mas de un metro en un objeto de 60 x 60 cms, suficiente para mi, y es el que uso es el modelo de construccion que presente aqui antes, y ya no busque mas, pues tal reune mis requerimientos
he estado experimentando con otros circuitos incluso un personal vlf de plato doble o y pues aun lo tengo en investigacion lo que pasa es que no he dispuesto de tiempo, y tengo otros proyectos empezados, de antenas o largas distancias pero no los he concluido pues no he estado conforme con los resultados, y asi seguire y cuando tenga mas tiempo me dedicare mas de lleno a esto
estamos en contacto
tu amigo

My TR is not finishet yet. I have no time now . I give You signal on PM. Greetz

[sonar]

We make a test on this TR Locator design with my friend JK...

What we think about this design at this time?

Detector is very unstable and give many stupid signals. Ground balance there was by good. Its realy good ground detector . Screen on RX module and generator + divider is good idea....

About TX transistors. We make a test on BD441 and 442. On 1,2 KoHm drive resistors voltage in TX coil is 35,7V - not 120V

We use 100 oHm there and this gaVe 90V in TX coil at this time. We think so this circut must be totaly 're-design'. Separation TX and RX PCB was be good.

We make some additional test with JK and trow out this by the window that PCB's

Test was made on Sevzirfo and Chemelec PCB with many corrections...

Now we make new one - own construction working with ground balance - not based on TR Locator...


Best regards...
