Thanks Stefan - this is what I feared.

Guess that I'll have to be more conventional!

I did look for you earlier this evening, but couldn't see your signal.

I hope your new FETs arrive tomorrow.

The L will be much to high and the Q will be very low (=lossy). Also it has a high parsitic C and will have a self resonance below 137 kHz. So it rather acts like a capacitor.

BTW capacitor, this is what i suggest. Simply use the 2 mH and a small variable capacitor connected to the wire and GND. Then you can accurately adjust to LF.
