Baracuda broken

[Qiaozhi]

Yes Muttiland

Now the detector works

OK - what was the fault?

[BKY1337]

Really?

[Andi68]

Jim Pugh mammy was the fault

Joking aside.

It was due to the setting, but I was looking for the error in the circuit

[6666]

What was the wrong setting ?

[Andi68]

With the scope I set the voltage exactly to 0V at Pin 6, Ne5534 and the sample delay with 16μs too small, VD 10 was broken.

And as I said, I was looking for the components, only today I tried a different setting without Scope

The circuit also works with C22 / 23- 470nF and C21-220nF

Replacement type for the 2N5485 = BF247

Now the world is alright for a short time

[kt315]

then time to do HH... you will see who from us is more angry my or Carl.

ahaha!

[Andi68]

I do not know which one I'm building, maybe I'll take a break too

Would you mind telling what are your coil specifications thanks ?

[Andi68]

These are rather test coils, so not yet valid.

Both coils are wound with copper wire 0.5mm, the number of turns I do not remember.

10cm, 1.3 ohms, 206μH

16cm, 1.5 = ohms, 295μH

For the small coil, I have the winding split into layers, it makes me a better impression than the 16cm coil.
