Aloha,
Considering recent posts, maybe you would be interested to hear about
the setup we used at KH6LC during the Stew Warmup. I brought my K3 SN
469, which has 2.7, 1.8, and 0.4 filters in the main and matched 2.7
and 0.4 in the sub. Now I know that I should have sprung for the other
1.8 filter

The filters don't need to be matched in bandwidth but they do need to
have the same frequency offset to avoid possible "beat note" problems
between the two (main/sub) synthesizers.
I didn't bother to pay the extra 60 bucks to frequency-match the 2.7 kHz

Today using SSB on 40M my K3 came up with pinched audio, the other operator
asked me to take the "clothes pin" off my nose. Full (and good) audio was
obtained with a power cycle. I was told that signal strength came up
significantly after the power cycle.
