Abstract
Unwanted audible noise on a mixed voice data channel is reduced by disabling an audio output device in a radio receiver or transceiver when the receiver determines that the RF signal received contains binary digital bit data. Alternatively, the receiver enables the audio output device when it determines that the RF signal received does not contain binary digital bit data.
