Topband: Which is best for copying the weakest DX - DSP or the ear-brain combo?

[Roger D Johnson]

Although I don't consider myself among the "highly-skilled and talented",  I
can't think of an instance where DSP made the difference between making
a contact or not. I do have an Autek QF-1A wired into the audio of the main
receiver of the K3 as the AudioPeakingFilter on the K3 is too sharp.
