LARRY,

He is calling what I believe to be multiswitch a voltage switch and he said he switched it out with no difference. If you guys are right about one side of the LNB being 18 and the other 14 when using a switch then I would have to agree it is looking more and more like the LNB. Could also be a bad cable or end on one of the sides that is shorting to ground intermittently. It's funny but my multiswitch clicks all the time even when nobody is watching TV. It would make sense when changing channels but I wonder why it does it when not watching TV?
