N1MM+ Logger, maybe others, have a feature that is selectable on/off (defaults to on) that randomizes the actual frequency used to populate their bandmap from incoming spots.
As another poster mentions, in a contest, DON’T ZEROBEAT if you haven’t got the absolute strongest signal. Much easier to be picked up if you’re 30-100 Hz off of zerobeat, preferably higher pitch. I likewise use the XIT. However, if you’re tuned off one way to have a higher pitch, the station you’re calling could be using the other sideband, and now you’re a lower pitch. Your signal good go unnoticed. Operating as a Rover in the GQP each year, it’s amazing how many folks call us over and over zerobeat, 10 deep. New county, wash, rinse, repeat. I can see stations even a KHz away on the pan, out of the passband, calling me. They’ll get worked before the others spread out.
