Hi Manolo.
This schematic drawn by me and it is from FG79. Not so good model, FG80 is better and has different schematic.

Regards:)

Hi.
60 cm is OK for FG80 or DC2008.

Regards

Can you write the values of this circuit?

I am sorry but after two crashes on HD there is n't nothing. I lost most of my work.
This is one of the reasons that i don't write so often.... and no mood to begin collecting schematics again....:angry:

hi, i can recover geo hdd data. If hdd stops, send it to me I can do data recovery.

Ohhh.... they gone for scrap..... time ago.
If will looking for maybe to find some dvds with schematics.
Other problem..... my pc has n't dvd player now :lol::lol:
Before one week my printer stop to work :lol:.
Maybe next week my pc stop working... so will be time to stop writing here :lol:

2022 did'nt come well :angry:

:)

I am doing data recovery business in Turkey. I could help with this.

!

Geo, I can also send you my files that i collected over the years in a stick if you like.

Mineoro DC2008
 

Hello! I will be very grateful if you send me everything about Mineoro DC2008

I ll search tonight my friend to see what i have got.;)

Thank you, but it's too late. HDs gone with garbage...:frown:

Jeg thank you.
Now there is n't reason. I have construct most of the existing schematics so now there isn't reason for the schematics. The years gone... and now no mood for constructions, also no mood for T.Hunting...:frown::frown:

btw.... maybe a trip to "Φουρνους" for fishing to give me energy :lol::lol:

Any time my friend!!! Any time...;)

Thank you!!!

Sorry bro. This circuit never published. Check your messages.

Hey Geo

Don't bother yourself to much. It will be good days for yours T.Hunting. You had have done more than 30 lrl's i have seen in your lab and all works - some are the best with special ferrite, some excellent like PD clone, others are normal and could do a job - a lot of small yellow coins.


Regards from the mountains. :)

Dragan i don't worry!!!:lol:
The best treasure is the health!!!

:):)

hello what is the transformer value primary 380uh secondary value in geo diagram?

Picture below

Hey Geo
What is your final conclusion on this? Detection happens through the loops or through the chamber?:oh:

Oscillation at the input of the receiver is too high as you have already seen. So it looks like that the signal coming from chamber is negligible and probably doesn't contribute as much as i was thinking!! I was ready to connect a switch so to separate the two circuits, but then i saw that you have already done it! (as always!!!:lol:)

ps. Does anyone know the exact length and diameter of the brass tip at the chamber circuit?


Regards

Try to make 2mH for secondary and wind one turn for primary.
Permability must be bigger than 400 (2000 is very good).

From my experiment detection happens through the loop. Maybe the brass tip works as antenna for electric field detection!!! (maybe).

Thank you Geo. Your experience is valuable.
Yes it is for electric field detection but everything show it doesn't work as intended. Mineoro failed at this point.

Is it possible to draw as a picture?

Ok, I found the answer to my question.
