           Checking VLCJ shows that the system temperatures                     
           have slowly decreased until it is reading a more                     
           normal value (~ 30 degrees).

           glitch at site. Bill Hancock was called up, he                       
           determined that due to rolling blackouts on the                      
           main island (local power company lost a generator)                   
           and weather conditions at the site, that it would                    
           not be practical to restart the compressor. As a                     
           result, the 20cm / 4cm / 7mm / and 3mm receivers                     
           are warm. Seeing high system temperatures at 4cm.
