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.

Mike,

Are you referring to a specific modulation mode?

How about adjacent channel interference issues?

I like your question.

I'd like to know whether it's ever been established that some very talented
hams can out-hear the best SDRs and/or DSP available. Can a skilled
ear-brain combo (such as some highly-skilled and talented 160 meter
contesters) beat state-of-the art digital signal processing when it comes
to copying the very weakest of signals buried in the noise?

I always thought Linrad was the best DSP software, though I never got it
working right here (older sound card issues in Xubuntu).

I asked the following question at

http://www.eham.net/ehamforum/smf/index.php?topic=104388.msg861047#msg861047
: "Are there any people who can hear weak signals with a good analog
receiver, who --if they could instantly switch their antenna and headphones
from the analog RX over to the best SDR made today-- simply couldn't hear
any better with today's best SDRs and/or DSP software?"

There's been a few opinions, but how about multiple valid tests?
