intermitant signal blips

[zionzr2]

On most of the channels I have noticed quick intermittant signal fades or blips. They dont happen very often but occasionaly enough to be noticed and a tad bit annoying.
It dosent seem to be weather or location related as my signal stats are in my sig. Does anyone else have these or know what i can do to prevent them?

Check your cables runs and connectors. If you have a switch, check it.
