Exactly. This one apparently ain't got one.
Thanks for your answer Esteban.
I already have my conclusions.

About equilibrium, this is the adjustment in the best sensibility point capable to be dislocate for the signal received by the IR.

As this may not have any IR, it's serving as a low Q and low induction receiver coil to match the front loop. It's working on the relative near field instead of a mid distance or far field.

You have to recheck it cause it's maybe as this:

red,brown,red,black,gray,brown

If so , resistor values are :

2120 ohm 0.05% (tolerance) 100ppm/°K (temperature coeff.)

Kind regards,
Max

This resistor coding seems to be a mystery. Personally I would have thought it was 2.12k as well, although Fred showed that it may be 212 ohms.
Now Morgan has removed and measured it - and it's 18K.
Perhaps the colours have been misread.

this resistor its grey,and the colours -brown,white,black,red,brown,red...one of brown colours looks to me gold ,but its brown,sorry...
The measurment is 18.09k

Thanks!
In that case it's a 19K 1% resistor.

[Fred]

So its 6 colours!
Now its different,read backwards, using the calculator:
http://www.samengstrom.com/nxl/2020/...e_page.en.html

It give 19 k 50PPM/ºC
Now that´s a high precision resistor,you should be able to calibrate your tester with it!

I hope we discover all electronic mistery aroud this device...

Hi,
I think the puzzle of resistor is cause we read it at reverse:

red,brown,red,black,gray,brown

I think now it could be :

brown, gray, black, red, brown, red

That means:

18000 ohm (like you measured) 1% (tolerance) 50ppm/°K

What do you think ?

Kind regards,
Max

Hi,
I think it's 18K cause if it's 1% (as probably is) the multimeter cannot read more or less than 18K +- 180ohm, so from 17820 to 18180 ohm:
he reads a few above 18K (18.09K, so just about 90 ohm more) so it must be 18K.

Kind regards,
Max

According to the colours given by Morgan, it's a 19k resistor. Where did you get the gray from?

Hi,
I suppose it's gray cause of value he measured... it's easy confusing gray with white on some kind of resistors ... colors can be not well defined or external protecting laquer can alter shine of bands.

He measured 18.09K... so if resistor is really 1% tolerance it must be 18K nominal... otherwise the multimeter read a wrong value.

Kind regards,
Max

[Fred]

Yes Max,you are probably right :18 K if it´s grey.
But in that case Morgan have to confirm if it´s grey,or white.Can be the multimeter too,or the hands .

Hi,
yes, true, I supposed he measured resistor without touching both leads with fingers... so just resistor value and not parallel with his body resistance.

But I think he did right measure.

Kind regards,
Max

Hi,
??? which code is it ? I don't know of any code that uses 5 bands just for value of resistance.

6 bands code I know is different:

first 3 bands are first 3 digits
4th band is multiplier
5th is tolerance
6th is temperature coeff. (ppm/°K) (that's optional band and is not present in 5 bands resistances color code ... they have just tolerance indicated)

for me it's 18K cause probably white... is actually grey.

Am I wrong ?

Kind regards,
Max

[Esteban]

I have resistors with the 5th band red and another orange. I pressume:

fifth band brown = 1% (of course, all know it)

fifth band red = 2%

fifth band orange = 3%

But for me isn't important here 18 or 19 K. This resistor maybe was used because is in "stock".

That must be really a mess as you never know from wich side of the resistor to begin.

hello
the colour is white,not grey.
I´m more worry with antenna and ferrite,why a simple resistor is so important...
This device works,and it will be very good if Esteban help us to build antenna,because i can´t dismantle this one...

Kind regards

Hi Morgan,
On PCB3 , lower left corner, i need to know transistors
numbers,and the component in // with R11.

Here's circuit #5 - the one that connects to the ferrites.

Morgan - Please can you double-check the component values, and in particular the component names. Your original diagram is difficult to read, and therefore some of the names (e.g. C3, C11, etc.) may be swapped over.

The RED and BLACK wires are most likely the power supply lines, but where does YELLOW go to?
Also, does anyone have any ideas about the correct connections for the ferrite coils? Morgan - if you can shed any light on this question, that would be great.

Hello
The circuit 5,yellow wire connect with bar 2c.
The cicuit 5, black´D` wire connect with bar 2G.
The circuit 5,red wire connect with switch on-off,sensitivity.
