I've assembled and tested the LPF kit from 160m to 6m. All the filters work as expected without adjustment except 6m.
The 6m filter starts to roll off very early and has a high loss in the 6m band (over 4db at 52Hz).?
I've checked for solder bridges and cold joints, continuity is good through the inductors and all the pads that should be connected. I can't find any shorts anywhere.
Any thoughts?
