Magnum on steroids!

Your lm 324 may be faulty or the tuning capacitor may not be holding

U2 pin 9,10,4,15.

14 number pin

on pin 14 of the lm324 what?

[Ruben2000]

I need your help friends!
I built MAGNUM TH; At Pin8 of the LM324 I get this signal (according to the images) and I don't know what it is due to. TX is at 14.7Khz. I would like someone to help me.

I built the DD coil. the CX winding is wound on top of the TX coil, but in the reverse direction as the TX coil. it is 1-3 turns. I put 3 turns. I need to know if the graphite shield is connected to the RX ground or the TX ground?

I connected it to the TX ground

Hello friends!
I configured my coils according to the image, that's the only way it works; CX only has one turn and is connected to TX in the same direction.

Cx 400mv should be But the signal is too bad .voltage too high I don't know how to set it up.How did those who set up and run this circuit make this coil?

[cnckecgo]

I'm having trouble setting cx with circuit.LM324 1st and 7th leg signal very distorted.Can anyone give a good description of how to set this up?
How will the cx adjustment be, the signals are very bad, the ground balance and the disc do not work well.

On the Magnum/Gold Mask is the graphite shield connected to the RX ground or TX ground? I'm having excessive chattering and false signals while searching. It is currently connected to RX ground.

Nikko 10 also gives details of it on page #4.

Here I share the wave signals on Tx and on U1 pin8 (LM324N).
Tx in 20uS, 5V.
Pin8 at 20uS, 0.1V.
