[Elecraft] K3/KX3 Operating Tip: APF (audio peaking, filter) for weak-signal CW work

How about making it possible to switch the APF on and
off through a programmable function button

Dick said:

It should be possible using a command macro.

AP0; turns CW APF off,
AP1; turns CW APF off,

SWH29; toggles DualPB which is APF if you have the K3 menu parameter
CONFIG:DUAL PB set to APF.

I say:

It IS possible, I did it  months ago using SWH29; and have been using it ever since.

I use button M2 to turn on  APF,  SPLIT, and SUB, and move VFO B 1KHz above VFO A.
All this is  to get the K3 ready for a DX pileup.
M1 undoes all of that after  I leave the pileup.
