Filter ringing is probably what he is hearing. The sharper the
filter
the more the filter rings. And it will ring to the tune of off
frequency
signals as well as on frequency signals.
I should like to disagree. Neither of my two filters ring. Signals 5
kHz off frequency sneak past the 500 Hz and the 250 Hz filters in the
Icom IC-706mkiiG. I know it is "blow-by" because I hear the signals
offset by the correct amount (2.5 kHz to 7.5 kHz) as high pitched
(Morse). I can tune in these signals and of course they are _much_
louder inside the filter passband. Signal strengths I am talking
about are 40 over S9 within the filter passband and S5 or less when
"blowing by" the filter.
I trust that this is not going to be an issue with the ic7000
