 Welcome
hi to all brothers
well  Smiley  i build snifeer xr71 Detecting
but i need to know hi i can use this circuit  Undecided
Possible to help me determine the value of a variable resistance in schema?? Pray
resistors varie (200kohm) and (trim 1 k ohm)??


and other varie resistors (220k ,10k.25k.25k,47k)??(and what is value puissance?)
 For example, what the result will be the value off  (47k ohm resistor)a min or max?
and what mode Battery
 and For the connections How can I do!!Between the varie   resistors?!
Please I need the information to be able to succeed in my work
 i would be grateful if you   help my Great
sory for my bad inglich  Wink

Hello housein , which schematic are you using ? I think the resistor values on your picture have been changed . Are you using this schematic ? Let me find the correct xr-71 zip folder  that has everything needed for the project . Regards.........Eugene

Hello . The xr71 schematic I posted here a few months ago should be the same as yours and the latest final version . Build it and let us know your progress .
Best Regards....................Eugene

housein;

Can you post a circuit diagram, perhaps I can tell you.... Im supposed to be an electronic (gee)whiz.... ha!

Ive been dabbling and making a living in electronics since about  1952, I am a Ham and my call is VE7EQP..... I do find locator electronics interesting, too.

Housein;
Must apologize semi-profoundly.... I didnt see all this thread an pictures, at first, because my browser often goes to the bottom of the page.... Now, I have collected stuff, and will go digest it like a snake after eating a big rat! (ik)
