for Carl - NC , gold gun AL 707 or 718

[Carl-NC]

Don't remember, I'll pull it back out and take some pics.

[Tim Williams]

I'll open the gold gun I have and see if it has white paint. If not I will post some pictures. I don't remember if it has paint inside or not.

Gold Gun

Tim,

What has been your experience with the Gold Gun?

Hi to all
Tim Williams , I am waiting see more about gold gun.
Carl, thank you.
Any body know about electronic section of gold gun?
Is it ion detector? Or is it long wave receiver ?

[Tim Williams]

Guys I will look at it today. It appears to be in the AM range. I will post some pictures also. The only responce I ever saw was North south line detection. If I turned the unit pointing either to the north or south I get a drop in digital value. Someone sent it to me to play with. He just purchased a mineoro unit. I will have it soon to play with and test.

Ok I looked at the unit I have here and the model is the 718. The board did not have paint on it so I made a schematic on the board. I need to check it again. I did not get to open the antenna yet. I will out today but will post tonight. I will tell you this. There are 2 jfets, HA17324 and filters. Not much more than that.

Here is the pictures and schematic. Carl let me know if your is different.

Good Job Tim!

Tim,

Thank you for going to the trouble in what you produced. Very interesting. Makes me wonder if their detecting the VLF Radio Stations carriers. With enough limiting you can really dig carriers out of the noise with a good filter on the output to clean up the harmonics. I've had real good luck using them on my loop antennas for the 160-190 KC license free band.

Do you have an inductance meter so the resonant frequency can be found out? This is the key obviously to seeing what the designer had in mind,but I'm betting on VLF beacons like the WADI receivers.

What say ye Carl?

thank you for the pictures and circuit description Tim Williams. Very good information.

Hi Tim Williams
Ok, thank you. it is very good reverse engineering also you working fast.
Please upload more pictures , specially from coil section .
Are you test it in real ? can you find gold and silver with it?
How much coil inductance ?
Best regards .

[FC247]

This can really find gold? Did you test?

[Geo]

Very Good

Hi Tim . Very good work. Gongratulation.
As i see in the photo of GG S1 must be with 3 positions (on-off-on) -(T..B..L-D), but at the schematic is 2 position (on-on). Who is the right?
Any info about coil ???
Thanks
Best Regards

[Tim Williams]

It is 3 position switch. I will open the coil up soon.

My GG looks exactly like Tim's, same PCB & components. However, mine is still covered in white gunk. May take me some time to get it cleaned out.

My recollection on some info I read some time in the way past is that the Gold Gun used ELF currents generated from the old submarine comms program. When that was shut down some years ago, Accurate Locators added a transmitter to the Gold Gun, and called it the "DLS." You can see one on eBay, right now, right here.

Thanks for the schematic, Tim.

ELF signals

Carl,

I once had a paper from a Geophysical publication that talked about using 60 hz for exploration away from surburban areas. Couldn't we use the european 50 hertz in the USA,should have no problem picking up the signal I would think with all the hundreds of miles of powerlines over there and many megawatts.
