[Elecraft] PF->RX EQ setting on K3

[Geoff Cottrell G3XGC]

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
