Nigel and all,
I hope I have not caused any confusion, BUT ...
I have been refering to the classical filter 'corner frequency' as the -3 dB
point, which does place the upper 'physical corner' seen on the display at
400 to 500 Hz. Perhaps I should change my text to clarify.
73,
Don W3FPR

I have just finished installing the KSB2 into my K2 sn 3029. Both the KSB2
and the MH2 were recently bought.
I downloaded both Don's, W3FPR, and Tom's, N0SS, notes for alignment using
Spectrogram. Don suggests the lower roll off corner at 300Hz and Tom's
plots show it at 500Hz.
