## Discrepancy

CREW REPORTED THAT THE WEATHER RADAR WAS NOT DEPICTING THE WEATHER AS SEEN VISUALLY OUTSIDE THE AIRCRAFT.  THE CREW TRIED USING BOTH AUTOMATIC AND MANUAL GAIN MODES, BUT RADAR REMAINED THE SAME.  THE CREW DIVERTED TO KCMH AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE WEATHER RADAR RECEIVER/TRANSMITTER.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
