I think I am prepared to do that

I had to use several ferrite cores to reduce the interference from 3.3
MHz to 15 MHz to an acceptable level. The volume and weight of the
ferrite cores I used exceeds that of the adapter.

About ferrite cores and tapped coils.... I was wondering about
something...

Imagine a tapped coil from a inductance value, let's say "i". what is the
effect of progressively introducing a ferrite core (wand) inside the
tapped coil? Reducing, or increasing "i"?

We were speaking about a Collins receiver. If I read well, it seems to
use this kind of feature. Could be better for experimentation, no?

p.s. I need to buy something to measure capacitance and inductance (RLC
bridge...).
