Wilson Relic & Coin 1V

[gl1945]

Can anyone help with the values of the Sensitivity/Depth and the Discrim Pots? I have the PCB's and the coil. All I need is these two values and to construct some hardware and I'll be up and running!
-Many thanks

i have a wilson rc 1v the pots are both 10k do you know what the chips are as the numbers are sanded off regards.

First post is from 2007

hello people and russians
i got an offer to copy the wilson board. now Mike can write here. welcome Mike.
we are seeking the pcb Mike could send it to me...

first pic from him.

This also is a 2007 year, but I was told the numbers of the chips that are sanding off of the chips. but as I do not know for use if the number is correct or not, I hesitate to post the number on the sanded off chips...

thank you Melbeta. i do not hope to get the schematic, but the pcb seems not so hard to copy even ICs are sanded.
some pics i have.
i have -
- tester of comparators and opamps. it will give good ID.
- tester of CMOS chips. it will give ID what a chip is functionally.

Just take chip numbers from this board. This is other Wilson detector. The chips are exactly same layout as other board, but surrounding components and tracks are somewhat different. I suspect that the chips will be the same.

The 16 pin chip on the bottom right corner of the PCB on both boards has a crystal resonator nearby, which leads me to believe that it is a CD4060. This is part of the oscillator which drives the TX.
You also see this type of oscillator arrangement on the Wilson atd/VLF 770 PCB on which a CD4060 chip is clearly visible.
The two 8pin chips are necessarily op amps. Or perhaps one of them is a LM393 comparator.

you are good researcher DB... i give you a contact of Mike, in msg. your english is perfect vs mine and
i hope you will navigate him on all aspects.

I found an old schematic drawing, and a HP engineer friend of mine, put in what he thought is the correct chips numbers. So check it out and see it they work for the chips. Okay, I managed to finally attach the .pdf schematic, with the unknown chips names. Now I cannot guarantee that the chip numbers are correct. But you can try and replace it with these chip numbers, and I think it will work...

I found an old Wilson IV schematic drawing, and a HP engineer friend of mine, put in what he thought is the correct missing chip numbers. So check it out and see it they work for the chips. Okay, I managed to finally attach the .pdf schematic, with the unknown chips names. Now I cannot guarantee that the chip numbers are correct. But you can try and replace it with these chip numbers, and I think it will work... Aaahhhh damn, some thing like Cloudflare popped up and will not let me post the schematic drawing. I do not know what it is, and why it is stopping me. But I have to live with what happens..... My problem is trying to attach something to a post. 9 times out of every 10, I am not permitted to attach something as it does not see to find my IP address. I use Firefox, and have it configured so that I am not tracked. And something cannot track me and stops me from posting. It does not hurt me, but since I have the answer, I cannot post the answer......

Whoops, I just noticed it let me post in above along with the attachment.... It is crazy!

thank you Melbeta. try to use more long way for the attachments - via GO ADVANCED, ATTACHMENTS (paper clip icon), ADD FILES etc

Bravo KT315.

You are truly a super hero of entire universal trash to treasure man. Great job for so many years.

So thanks
