SNIFFER XR-71

OK Aban Thanks. Q7 (PNP)from XR71 is diference from Delta Pulse(Q8-NPN), the same with resistors R36 and R37. Now everyone who like XR71 can take the pdf file who is attacted in the forum. By the way does anyone has manual from XR71 or Delta Pulse?

[aban]

It is the same of Delta almost

Hi Geo,
The Xr71 is the same of delta pulse,the differents between them is in 4066 gates connection and frequency only.Some of the pepole belive that the XR71 is stable than deltapulse.Both are good pi detectors.

Hi Aban. I don't like to construck it but i want to see the differences between XR71 and Delta Pulse because i believe that is the same diagram. Any way thanks for the pcb files.

Hi Aban

thanks for your P.C.B file .

I have two kind circuit diagram about XR-71 sent by my friendes but I do not know true traced .

Thanks a lot here from Mrand and Esteban and Geo.

Please send me your correct XR-71 diagram .

I decide trace new P.C.B. in another size .

XR71

Hi Geo:
I have the XRshematic.I tried to uploud it in the froum,but it is big than 250K for upload in the froum.Now,i upload the diagram wiring that you can know the information from it.If you make it from my files,you`ll be succesful easily.

[Geo]

Hi Aban . You send me the pcb file not the schematic file. If you haven"t the schematic file then i"ll try to create it from pcb.

I sell XR-71P (sniffer) adjusted ready to use KIT pcb or naked pcb only
email to: [email protected] Full copy of the original XR-71P with factory made pcb.

I like this detector

Please,

Send me this information, i am working with protel 99 too. Can you send me the schematics of XR71.

The indications to made this locator, and others information that you consider important.

What about the coil using in this design,

What shape, diameter, wire gauge, and turns ???

XR71

Hi Geo,

see your mail box.I sent you the XR71 protel99se file in your email.

[Geo]

Hi Aban. I am working with Protel 99SE so if you send me the xr71 file i can convert it to gif and to put it in the forum.

PSll

This is an old version of psll.The new version of psll have microcontroller 68H... series.

You guys are strange! WTF is this panel of Pulse Star? I can draw it better using paint shop...reaaally funny actually is junk..btw Sniffer's adjustments are more interesting than the circuit itself.

PULSTARll WITH DISCRIMINATOR

Ok,It is good mashin,but i am converting it from analog display to digital LCD.The shematic of XR71 is in protel99SE.I am trying to put the good shematic detector and professional detectors shematic in the froum step by step.

Hi Aban
Please upload here PUSE STAR II and your SNIFFER XR-71 circuits .
