Nice close-up. Choking of some of the lines seems OK, but not the

Could you find in this picture choke?

What material is used in the ferrite?

For transformer - low magnetic permeability (50) for chokes - high.


So, now where is the schematic of the biasing for these
varicaps? If those two clear insulation lines are going to the loop,

It's lines from resonance loop to amplifier.

Does this mean the varicaps are across the loop?
