Thanks.

I guess the issue with tuning of the K2 LPF inductors for increasing the
10/12 m output is that the cut-off frequency may in a few cases be too
low, so that the attenuation a the fundamental is too high. The cure
should be to decrease the inductance, ie. to spread the turns over a
larger part of the core?
