This is the good capture for 100 ohm + 1mH
At 16 kHz (theoric reactance = resistance; works on simulation, but on real circuit resistance is still bigger )

At 20 kHz we achive the point.

Next I tried with a bigger resistor. I'm using a pot set at 925 ohms.

200 kHz. Theoretical/simulation happends at 147 kHz.
The ratio of the "freq offset" increased.
From 20/16 = 1.25
To 200/147 = 1.33
Doesn't it suppose to decrease?
I mean, using a higher resistor, my generator output impedance is now negligible.
About the LC,...
I'm using a pure LC, no resistor.
