Abstract
Techniques are described to determine that an electrical short has occurred on a communication channel based on monitoring a power level of the communication channel with respect to a reference power level. In an implementation, the aviation communication apparatus includes a first voltage source that provides a first voltage input to a first communication channel of a stereo jack for a headset, a voltage monitor that monitors a voltage level of the first communication channel with respect to a reference voltage level of the first communication channel and determines that an electrical short has occurred on the first communication channel based on the monitoring. Accordingly, an electrical short indicator may indicate responsive to the voltage monitor determining that the electrical short has occurred.
