Maintenance

[Tom Droege <tdroege2@earthlink.net>]

It looks like July is going to be a disaster for data taking.  All three
systems were sick today.  TOM1 has been sick for a week or so.  I ran it
with the chiller on constantly because I suspected that the chiller
switch was causing a noise problem.  This caused a lot of condensation
on the cameras and this got into the connectors.  The result was that
the connectors on both cameras failed.  It looks like the I camera is
fixed, but the V camera refuses to communicate.

Recent electrical storms seem to have killed the network card in TO3. 
It was the last thing I suspected.  Some time ago I bought 10 network
cards for $40.  One never expects the cheap card to die.  Sigh!  I am
down to my last spare.  I thought I was being really silly when I bought
10, but figured I might as well buy 10 at the price instead of the 2 or
3 I needed at the time.

TOM2 still has the problem where it wiggles in declination at some
angles.  I look and look but don't see anything that binds the axis.

Sigh!  Generally a discouraging couple of weeks.  The only good news is
that it has been raining and I could not have taken data anyway.
