When you are a "Superbowl" Operator and there are multiple stations keying down trying to be heard, it is wise sometimes to slide 'off the channel' to one side or another to be heard; the "mud ducks" are slobbering in their microphones on the channel while you and the person you are communicating with are are uninterrupted a few KHz off.
That's a real problem for "Channelized Hams", if your signal isn't on X.000 or, X.500 hertz, they cry about your radio is "Off Frequency"; No, my transmitter is on what frequency it is on and your receiver isn't. A symptom of your radio's receiver frequency being tied to your transmitter frequency.

Well I don't do a lot of 6 meters. So channelization is foreign to me except for being a kid on CB.
