During the NAQP SSB contest in January, I heard a single-op somewhere in the midwest calling CQ with a steady S9 +20db signal that was so overcompressed that he was literally not understandable. Nobody was answering him, but lots of guys were commenting on his bad signal behind his back. So I gave him a call and told him all of that, and suggested he crank back the supercharger. He backed off the compression three different times before he sounded crisp, and by the time he got there his signal was S9 +5db but FAR more intelligible.
There were many South American contest stations during the recent ARRL DX SSB contest that sounded like voice-modulated spark gap transmissions ... horrible stuff. It often took several tries to ferret out their callsigns, and what they thought they gained in terms of quick QSO rates is beyond me. The great thing about the K3 is that by speaking into the mic with the monitor set loud enough to drown out your own voice (the one inside your own head even while wearing headphones), you can set mic gain and compression for your own perception of crisp intellgibility instead of maximum average power out. The two are definitely not the same. 73, Dave AB7E Julius Fazekas n2wn wrote: > Thanks Jack! > > Based on your presentation and the voice settings, I'll be dropping my > compression back a notch.
