Keeping your competition on a distance
This is a grim example how to keep your competition on a distance! I won’t mention calls, but this screenshot is from the IARU HF contest this past weekend and this is a HQ station. If you look closely to the waterfall display you notice the splatter lines at least 30 kHz down.
Yes, he is strong but others are too without splattering. The result is that other nearby stations keep their distance and the splatter-maker has a very clear and clean place on the dial. Good for him, bad for others trying to work the weaker DX stations around him.
Looking at cluster spots from the weekend I notice that others also complained about their splatter. Even on other bands!
You draw your own conclusions.
