1. Yes, you should see an 8170Hz signal no matter what.. It should be almost nothing on pin 1 of the LF353 when nulled though.

2. Signal will be maximum at resonance but at the same time minimum when nulled. (So look for a maximum while adjusting phasing but a minimum while nulling).

What is the value of L for your RX coil????

thank you, this is what i was looking for!!
i don't have LC meter but when i used coil calculator it gave me about 6.2 mH.
so i must first don't null my coils, then i must change caps to see maximum resonanse, ( now my tune is good) , then i must overlappe my coils litle by litle to see minimum resonance at signal(so this is fine null and fine tune too), tel me know if i am wrong!
thanks in advance

Yes, that is correct! So, if your RX coil is around 6.2mH then your capacitor for resonance should be 61nF. That would be the best place to start and then either go larger or smaller. http://www.whatcircuits.com/lc-reson...cy-calculator/

thanks a lot Mr Don, this is great help for me!
other thing i can't open the link since it have JS/Agent.NCA trojan!!
thanks a lot again
