Brett,
Every contest I run into several stations on CW who actually transmitt 3
signals. Main signal is usually 59+30 or more and two side bands spaced 1-2
kHz from the main can be as loud as 59.
No wonder, close by skimmers decode then on these sideband frequencies.

Another dimension to this skimming thing is spotting on wrong frequencies.
Or the wrong band. Take the RBN data for a day - a non-weekend day is
better, as few stations actually on >1 band at once then - and look for
the same call spotted say 3 kc or more from others at exactly the same
time.
Open that window to a more realistic minute or two & see just how many
there are!
