Narrative:

Callback conversation with reporter revealed the following: the reporter stated the blind spots started with the installation of a new ASR-9 radar system. The radar would not detect non transponder aircraft departing runway 14 at hif. When the aircraft turned the transponder on a primary and beacon target were displayed. An evaluation team was sent from washington headquarters. After analysis, the team found a design problem with the ASR-9 and a fix is going to be made. The problem is with the mti system of the radar. Procedures have been adopted to preclude non beacon aircraft from departing hif.
