ABSTRACT:
Disclosed herein is a communications system implementing a microphone wirelessly connected to a half-duplex communications device, such as a two-way radio or a radio-simulating cellular phone. The microphone may incorporate a transmit/receive switch wherein a transmit signal is wirelessly transmitted from the microphone to the communications device to direct the communications device to enter into a transmit mode. The microphone may communicate with the half-duplex communications device through a magnetic induction link.
