Hi all,

as I tested intensively the new VBF design, it looks quite good.
I noticed significantly less insertion loss on lowest BW of the VBF (b01/b02 settings).
Specially it is noticeable on weak signals where there is not so much attenuation on signal...

Boris made an excellent job on that design.

Thank a lot Boris,
