sort of familliar with pic's lately,i also know it is impossible to re-read it once is protected.
It was possible to gain some success with the early 16C84 ic's, but that bug was fixed
on 16F84 series. On 16F873 series is impossible to do that. The whole design is splited on 3
parts.Simple receiver, some kind of converter/buffer and Pic part with eeprom and rs232
(or simillar)communication part.The pic pcb is very "pro.look-like" and it seems that they used
already prepared "general use"pcb and just programmed pic.The other two pcb's look very
"hand made" and simple and can be easy copied.As i presumed, you need a ulf receiver and a good
software to analyze received data.Also there is a data logger included in the design with
16 000 samples capacity.
When u switch it on the pc, software transfer data from logger in to pc and later u can analyze
it on many ways."Nice and clean". Despite the price of 8000 e, still i would like to copy it and
make another.Is there any chance that somebody have .hex for UG12 pic !!??? I do have software
for pc also, which comes with device.It looks very simple and easy which provokes me very much!
O.K. ...now ...is there any chance to get that .hex for pic or not? If somebody know how...come
here and join the company!
This is it. I am gonna continue with my own ulf project and when ready i do intend to post all
here....for everybody to see.
I am very interested about your opinions people....come and talk..
regards

I talked to you a few years back about the ug-12. I could never make mine work as I am too far from the tx's, however I wondered if you would sell me the chip out of yours if u are not using it anymore. i did like the processor and software and wanted to use it with something else at some point. If you still have the PIC, and would sell it or even the whole board, please shoot me a price. Thanks, Mike

Ivconic don't read this site!!!

[buscadero]

OK, I will try to find him somewhere else.

Hi buscadero!
You might be an interesting booklet on UG-12?

Thanks, sheshko, but all I need is the chip out off of the processor board.

For the end i sugest a simple 10.7 IF from some radio
.....for example u can use some based on CA3089 or even
better on MC3357 or similar...3361,3371,3362,3359.....
even a simple transistor design would do a job.Further
analyze can be obtained,taking a part of signal from
later stage....(i am preparing some schematic on that).
For antena I would sugest a loopstick or even better
special design i am preparing and gonna post it soon.
You may experiment by winding 600-100 wind. of Cul 0.5mmm
on ferrite core, 30-45cm long and 3-6cm thick.
This is just an idea,I am very busy these days and off
.net so here is a little something just for a start.
regards....

your detector mod = gun detector or pistol detector or vlf metal detector ????

vlf metal detector ?????

yes it' a anomaly detector based on vlf tx/rx system

hi friends
Does anyone know what's part number of this varicap diode?
best regards.

[reza vir]

Hello my friend
This is a capacitance diode
Works in his suffering VHF and UHF
You can use the same

Hi dear friend
thank you for responce.
but frequncy range of this receiver is on VLF to LF band (30khz to 300khz) and this not a HF receiver.

[Agraz]

to capture vlf waves below 150 khz, I think you can also use a radio with coiled wire in a ferrite rod as an antenna:

[Agraz]

or if you do not have that radio with tuning in vlf, you can made a vlf converter for a shortwave radio, I can capture
several meters away, the TX of a two box detector that works in 90 khz.

can you share the TX schematic of your two box , thanks .

[Agraz]

I do not have the thor model transmitter schematic, I only have the explorer model that is similar but less powerful

Thank you !
