[Elecraft] KX1 IF Filter Tuning

[John C Ceccherelli]

You can add S/N 179 to the list.  Although I haven't put it on any test
equipment, my ear says at the narrowest setting, the peak response is at
around 400 Hz and the 600 Hz I want is about half as loud compared to wide
open (-10dB or so).

Since I like a lower CW note and because a lower pitch is far more
effective (psyco-acoustically) for weak signal, I just RIT down to the 400
Hz range and I'm happier than a pig in slop.
