satellite feed problem

[<kgcr@kgcr.org>]

A satellite question that has us stumped:  Overnight we lost our satellite 
feed.  It went off sometime after midnight.  Temperatures dropped to the 
single digits overnight.  When the sun came up the satellite feed came back 
and the ebno has been steadily climbing.  The ebno is now 9.2.  Temperatures 
are still in the single digits.  We have a clear plastic dome over the 
bottom of the LNB housing and, as least as close as I can tell, there is no 
moisture in the unit.  We've been having problems with clipping over the 
past six months or so but that always came during the middle of the day, 
usually between 1 and 3p.

Any thoughts?
