Are you using or boosting the receive EQ in CW mode? I believe at
lower BW settings the EQ will be negated thus you are losing the effects
of the applied boost. As an operating practice, little to no RX EQ
should be used for CW mode as EQ typically creates phase effects
impacting harmonic content of the audio signal. It is always much
better to "attenuate" as opposed to "boost".

“Selectivity”???
Do you mean DSP filter width?
Narrow width does decrease the background noise.

I noticed that during the contest, that if I selected 50 or 100 Hz selectivity,
the audio would drop way down. It didn't used to be this way. I tried reloading
an earlier version of the software but couldn't figure out how to do it.
Hope this comes through, finally!
