Abstract
An arrangement for preventing inadvertent transmission by a push-to-talk transceiver that might join a communications channel. After the push-to-talk switch has been activated, an average background noise level is established. Audio from speech, for example, having peaks greater than a predetermined percentage of the average background noise level are required to maintain the push-to-talk function activated.
