[Boatanchors] Low Pass Filter Comparisons

[Michael D. Harmon]

Hi,

Can anyone give me an idea of the relative performance of the B&W 425 
and the Johnson 250-20 low pass filters?  I believe they are both 
supposed to be rated at a KW or so (probably AM).  I'm looking for one 
for my AM/CW boatanchor station and they both seem to be readily 
available, but I may as well get the one with the best specs and 
reputation for quality.

Anyone have any preferences?

Thanks,
Mike, WB0LDJ
