This morning, a quick trip to the field:

• reinstalled csat3a.1.5m.a1.rel (the same head and box that was removed yesterday, but now after changing AA to 50, as suggested by Larry at CSI).  Green Lights!
• swapped in a fresh battery to lconvm/lconv2
• connected power monitor to lconvm
• swapped out Gill.0.2m.uconv1 and its cable that had some blue corrosion and had died the night before last
