For CW reception of weak 160m DX, I recently tried tweaking up the RX EQ
so that the sidetone frequency is enhanced and other frequencies are
attenuated. I think this works quite well as a primitive extra audio
filter. While the settings are great for CW, they are no good
(obviously) for speech. Does anyone know if such a "home brew" AF filter
CW response curve setting could be stored using say PF1 button, and then
be reset to a flat response using say PF2? Otherwise it gets fiddly and
time-consuming to keep tweaking each of the eight filter frequencies.
This would be handy
