Bottom of the barrel? What did you replace then with?
5B4AGN filter sets that I built from his kits. Measured data in the link
I provided.
N6RNO owns two sets of W3NQN filters that we use for CQP, 7QP, and FD in
W6GJB's contesting trailer.
Actually, I would
replace all of these if I could find a reliable unit for similar cost.
Cost is the root of their problem -- they are built with under-rated
caps and mediocre relays, and a lower grade filter design. Look at the
photos of the filters in my report, especially the photo showing three
different filters for comparison.
