Yes, it did detect a LNB drift. What does that mean?
Think of LNB drift as a loose radio knob. Slowly, the knob kinda works it way away from the FM station you are tuned in to. If its just a little off, it isn't too bad as you can get the station still. However, if the knob is really moving away from your radio station, you get all kinds of static (noise) and can't get the radio station to come in clear. Eventually, a really bad knob that drifts too far from your radio station would mean you get nothing but snow.
