[Elecraft] KFL3C-400 offset?

[Grant Youngman]

Just an opine.  Since these are ROOFING filters, and not the means of determining the radio’s ultimate selectivity, you may not notice a substantial performance improvement of the radio with 8-pole vs 6-pole filters.

I have my flame suit on, just in case — (it can be almost guaranteed to be needed around here).  :-)

I had email exchanges with K3 support, most of which were helpful, but the question about a KFL3C-400 eight-pole filter went unanswered.  They seem to have a problem in this area.  Not exactly sure why.  Uncharacteristic.   So, I have two 6-pole 400Hz filters for sale!
