Having just endured another weekend of truly awful audio with WPX SSB, I
couldn't even get my ear/brain to decode many of them. I heard at least
50 stations with audio so badly distorted, muffled, or wildly
overprocessed that I could not copy them, and at least a hundred more
where the poor audio quality made me take twice as long to complete the
I'm not suggesting that we don't use processing/eq/compression -- these
are excellent techniques if done WELL, but they destroy speech
intelligibility if done badly. I run my K3 with the three lowest
frequency bands set for maximum cut and some cut of the fourth (400 Hz)
band. The remaining bands are set flat. I have compression set for 10 dB
on peaks, and I carefully set computer playback level so that the radio
is not overdriven.
PLEASE -- the next time you are setting up for a SSB contest, either
listen to your own audio on another rig or get another ham to listen
critically to your audio.
