I remind everyone that I paid $2000-$1700 for these devices.  They quote 
$40,000 for a class 1.  So there are possibly problems.  CCD-World has been 
helpful in the past about problems.  First we have to understand what is 
seen, then possibly we can get help for a fix.

We also are operating much warmer than most places operate similar 
devices.  We could be seeing unfamiliar problems.
