## Discrepancy

DIVERTED TO MIA DUE TO LOSS OF WEATHER RADAR. FLIGHT CREW REPORTED A GREEN BAND ON THE RADAR DISPLAY APPROX. 6.5 MILES IN FRONT OF AIRCRAFT.  MAINTENANCE REPLACED C-BAND WX RADAR CONTROL PANEL.  SHOP FOUND CONTROL PANEL TILT CONTROL MISADJUSTED TO 14.5 DEGREES DOWN WITH TILT CONTROL SET AT ZERO.  IN FLIGHT, WITH THE TILT CONTROL SET TO ZERO, ANTENNA WOULD BE TILTED DOWN 14.5 DEGREES AND WOULD BE RECEIVING SIGNIFICANT GROUND RETURN. THIS WOULD SHOW UP AS A GREEN  BAND ON THE RADAR DISPLAY.
