Narrative:
The transmitters system at hayward is operated through a microwave remote site. Since sep/xx/96 the microwave system has been inoperative. It is expected to be OTS for 10 days to 2 weeks. During this time all ATC communication is being performed with a battery backup transceiver for local control and a hand held transceiver for ground control. This creates an unsafe condition due to the fact that aircraft radio are able to override the backup radio. In the event that local has to issue a safety alert, traffic alert, or go around instruction, local cannot be certain the transmission will be received without other aircraft radios blocking it. Further, the quality of the radio transmission is greatly reduced, resulting in numerous request for repeated xmissions and greatly adding to the controller workload. Further, no training is able to be performed until the microwave system is restored.

Title: ATC RPTR CONCERNED THAT THE PRIMARY COMS SITE IS OTS AND THAT THE BACKUP BATTERY POWERED UNIT HAS TO BE USED UNTIL REPAIRS CAN BE COMPLETED. REPAIR WAS ESTIMATED TO TAKE 10 DAYS.
Narrative: THE XMITTERS SYS AT HAYWARD IS OPERATED THROUGH A MICROWAVE REMOTE SITE. SINCE SEP/XX/96 THE MICROWAVE SYS HAS BEEN INOP. IT IS EXPECTED TO BE OTS FOR 10 DAYS TO 2 WKS. DURING THIS TIME ALL ATC COM IS BEING PERFORMED WITH A BATTERY BACKUP TRANSCEIVER FOR LCL CTL AND A HAND HELD TRANSCEIVER FOR GND CTL. THIS CREATES AN UNSAFE CONDITION DUE TO THE FACT THAT ACFT RADIO ARE ABLE TO OVERRIDE THE BACKUP RADIO. IN THE EVENT THAT LCL HAS TO ISSUE A SAFETY ALERT, TFC ALERT, OR GAR INSTRUCTION, LCL CANNOT BE CERTAIN THE XMISSION WILL BE RECEIVED WITHOUT OTHER ACFT RADIOS BLOCKING IT. FURTHER, THE QUALITY OF THE RADIO XMISSION IS GREATLY REDUCED, RESULTING IN NUMEROUS REQUEST FOR REPEATED XMISSIONS AND GREATLY ADDING TO THE CTLR WORKLOAD. FURTHER, NO TRAINING IS ABLE TO BE PERFORMED UNTIL THE MICROWAVE SYS IS RESTORED.
