Narrative:
There is a continuous problem with false targets in all quadrants of our radar coverage at stl/T75. It is logged every day on our daily logs. Apparently nothing is being done. Callback conversation with reporter revealed the following information: reporter indicated that he believed that a ucr had been filed regarding the false beacon target presentation. He also stated that his union was pursuing this as a safety issue through their central region office. Supplemental information from acn 334508: the data blocks on our ASR-9 radar scopes at times will start to quiver and jiggle. The problem, according to maintenance, is old equipment and dirty switches. The fix? They have us rapidly FLIP the center/de-center switch.
