K3 Receive equalizer affects narrow settings

[WA9VEE]

I think this is an interesting result.

I was attempting to enhance CW tones to the exclusion of highs and lows, so set Receive equalizer to:
1-3, 7-8 set to -16 and 4-6 set to +16; CW pitch 630.

With 250Hz filter kicked in, Bandwidth .05 and .10 are very attenuated no matter what RIT controlled audio tone is produced.

The two narrowest widths do not have the Rx EQ available.  What you are
hearing is the loss of +16 dB boost when you go to the narrowest
selectivity settings.  You can get around this by not using boost of the
desired frequencies.

In general, the Rx EQ will not add selectivity. It is *not* an
additional filter stage.
