Quick update before Francina brings her class here for a tour....

lconvm (and thus all lconv networking) died again last night, along with lconv2, at 22:00 and revived just before I arrived this morning.  Presumably, this is due to power loss, despite us adding an extra solar panel and swapping in 2 new batteries yesterday, with an entire afternoon of sun coming through scattered/broken skies.  lconv1, lconvt, and all rel seem to have stayed up.

Campbell reports that all 5 sonics that we sent to them as dead were working fine as received.  This is really annoying. So far, we have 3 dead CSAT3As here – both of our spares and one deployed (now at 1.5m.a1.rel).

Given the guy tensions measured yesterday, every tower will need to be retensioned. <heavy sigh>

    PM addendum:

    • After speaking with Kurt, we decided not to chase the guy wire tensions.  The towers still seem to be pretty solid.
    • Spent most of this afternoon back and forth with Campbell.  By changing an internal QC parameter (and changing it back!), we can get a "bad" CSAT head to report data that <seem> reasonable, but we want to be sure before calling this a "fix".  This conversation is ongoing.
    • GillWO.0.2m.uconv revived itself, undoubtedly with the same water-in-the-connector problem as before.  I'll swap the cable and sonic tomorrow to be sure.

    I intended to add a pmon to lconvm today, but didn't get a chance.  (The battery box has to be moved closer to get the USB cable to reach.)  Another tomorrow task.  We're wondering if this has an excessively high load for some reason.  I'll also plan on changing out the second battery with a recharged one.
