## Discrepancy

AFTER TAKEOFF FOUND RADAR UNSUITABLE FOR FLIGHT OPERATIONS INTO KNOWN CONVECTIVE ACTIVITY. ON ROTATION WX RADAR DOES NOT STABILIZE REGARDLESS OF PITCH KNOB SELECTION, RADAR SHOWS COMPLETELY COVERS SCREEN. DURING CRUISE RADAR INDICATES FALSE TARGETS ON ALL PITCH SETTINGS.  AC RETURNED TO DEPARTURE WHERE IT LANDED WITHOUT INCIDENT.  POST FLIGHT INSP WAS PERFORMED. REMOVED AND REPLACED NR 2 VERTICAL GYRO, RADAR ANTENNA AND RADAR INDICATOR. OPS CHECKS WERE SATISFACTORY. AC WAS RETURNED TO SERVICE. NO OTHER DEFECTS WERE NOTED. (K)
