## Discrepancy

WX RADAR DOWS NOT PAINT FULL SCREEN IN "WX" MODE.  RETURNS ARE BLOCKED FROM APPROX 1 O'CLOCK POSITION THROUGH 3 O'CLOCK POSITION.  DOES THIS IN WX+T MODE AS WELL.  SEEMS TO WORK FINE IN MAP MODE.  PERFORMED WEATHER RADAR SYSTEM OPERATIONAL TEST AMM 34 43 00 710 802 001 & WEATHER RADAR SYSTEM TEST AMM 34 43 00 730 802 001.  OPS CHECK GOOD.  NO HISTORY LAST 90 DAYS.  THIS IS A SUCCESSFUL GROUND VERIFICATION.
