This is an interesting discussion. Before I purchased my K3 in 2008, I had become addicted to narrow selectivity with my previous rigs, and was routinely tuning the bands with cascaded 250 Hz filters. Since I'm nearly 100 pct. CW, I purchased a range of crystal roofing filters to try out in

I'm wondering if the RFI is primarily due to the condition of the coax? If a tuner is located at the rig-side of the coax, and the coax is at high SWR, it could possibly be a cause for coax radiation. A test might confirm that. Perhaps you could find a spot on 40m where the SWR is null, and no
