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,

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.

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 .

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.

[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.

[Geo]

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?
