I fix a wave for rx and its ok but still the wave of tx asharp and big

[basellafe]

What do you think could be the problem

Vdi lugatek

I built
Vdi lugatek, I would like to remove the counter from 500 applications, I could help
thanks

Hi onuba, i would like to ask you about that Lugatek VDI...
Do you need to adjust vdi number's by rotating discrimination pot or no?

[onuba]

Not for sensitivity and reset to 00

Have You the full Program for PIC? ;–)

Look's very cool, would be so nice if u can post files...

Hello,
I have problem with my IDX. I made dd27 coil:


TX 530mH 0,7 6,60kHz 14Vpp
RX 35mH 0,15 4,64kHz


TX/RX phase about 90 degrees 150-200mV


Discrimination and PP works well only the GEB has a problem. I have 50k pot for the GEB and ferrite is invisible untill I set the GEB pot to 2kom then is visible to 50kom so the regulation is very unuseful. How to set this point in the middle position of the potentiometer? I increase 220p cap to 330p, decrease it to the 100p but no change. Any ideas, help?

50k is a lot of ground to control, rather 30k. Set ground control to the middle position and the selection of the reception capacity of the winding device to Achieve never seen ferrite.

Sounds like the phase is too far out. Try changing the RX capacitor a little

So RX coil needs correction number of winding? But what with recommended RX resonance frequency? It will be change.

Below is my TX/RX coupling
