  • Mitigating echo and spurious audio noises in radio communication systems
    Patent number: 10609522
    Abstract: Audio output of a radio frequency (RF) portable communication device is controlled. A first portable communication device (PCD) uses an audio transducer to generate one or more audio tones in response to a voice transmit operation initiated by a user of the first PCD. One or more characteristics of the tone or tones can be selectively controlled in accordance with a first talk group which is in use by the first PCD to facilitate the voice transmit operation. The one or more audio tones are received at one or more second PCDs different from the first PCD, where they are used to selectively control an audio output volume of the second PCD.
