[Elecraft] K3: honest question re Audio Peak Filter

[Merv Schweigert]

AMEN.  what APF does is put rare DX in my logbook that most of the
others sit there and cannot pull the callsign out of the noise. 
I call it receivability,  you can have the best specs on the radio in the
world but if you cannot pull that weak one out and copy the call your
just second class. 
I can say over and over that my K3 is by far the best radio I own, but
it cannot pull the weakest signals out of the noise that the 1000D APF
can.  So when I have to revert back to the 90s radio to get the job
done specs mean nothing.,   if you never DX on 160 or even other bands
at the noise level you will never need APF.  Different tools for different
uses,  no one gripes when you guys ask for scrolling power up banners,
now that really helps the K3 receive better eh?
