[Elecraft] Selectivity

[Vic Rosenthal]

This is probably because you are using the rx equalizer and have boosted your preferred cw pitch. The narrowest filters (50 and 100 Hz) do not support the equalizer, so the boost disappears (this is slightly oversimplified, since there is an option for the type of DSP filter used for the narrow bandwidths that also affects this).

Anyway, the trick is not to boost any frequency ranges — just have the equalizer cut the ones you don’t want.

The rx equalizer doesn’t do much on CW with narrow bandwidths anyway, since the bandwidth determines the range of pitches that you hear.
