Notes: * = Entries where data was affected. % = Entries where data may have been affected. & = Entries where the site tech was called out. wea = Weather entries: MF# = Maintenance form or major downtime category associated with a problem. %AD = The percentage of an antenna affected by a problem. AMD = Total antenna-minutes downtime for a problem. Tsys = TP/SP x Tcal/2 ACU = Antenna Control Unit FRM = Focus/Rotation Mount RFI = Radio Frequency Interference VME = Site control computer CB = Circuit Breaker vclock = Program that compares site clock time to a standard.
