TENNIS RACKETS FOR "OPEN SCORE" A CRYSTAL-CONTROLLED FM TRANSMITTER WAS BUILT TO FIT INSIDE THE HANDLE OF THE TENNIS RACKETS. A CONTACT MICROPHONE ON THE RACKET PICKS UP THE SOUND OF THE BALL HITTING THE RACKET. THE SOUND IS BROADCAST TO A RECEIVER OUTSIDE THE TENNIS COURT AND FED INTO THE SPEAKER SYSTEM. THE FM TRANSMITTERS HAVE 10 mW OUTPUT AND OPERATE AROUND 90 Mc. ARTIST: ROBERT RAUSCHENBERG
