SGP/TWR/C1 - Reprocess: 25m and 60m T/RH Comm Lines Switched

On 3 March 1997 an activity of unknown nature took place at SGP, causing 
the communication lines to the 25 and 60 meter T/RH to be switched.  The 
data indicates that the switch occurred between 1630 and 1700 GMT.  I 
submitted a work request to site operations to determine if the two levels 
were switched; they found that they were, as I suspected.  It is not clear 
where this occurred, although we do know that it did not happen at the 
tower CR21X dataloggers location.  The communication lines were temporarily 
"switched back" at the logger location on May 28 at 2110 GMT until it can be 
determined where the switch was actually made.
