The sodar-RASS went down on June 12, apparently due to heat related issues.  A 220/110V transformer appears to have burnt out - since this runs the computer enclosures air conditioning, the computer overheated and shut-down.  In addition a temperature safety switch in in the antenna electronics box also tripped.  This is separate to the enclosure so shouldn't be related, but if the environment is hot enough they could both have failed on the same day.   Replaced the transformer with a temporary arrangement and reset the temperatue switch - the sodar was running again from about 16:30 UTC.

    Sodar went down again after 0 UTC (June 14) - it appears the computer didn't come up after it's nightly restart.  Restarted around 13 UTC.

    Sodar went down again on June 15.  It appears that the upper temperature switch in the antenna electronics box tripped again.  Given that it was running last night and the box had been in the shade most of the time since, then it appears that this switch is faulty.
