Airplane pilot communication aid

DETAILED DESCRIPTION It is the object of the present invention to enable a pilot to hear his transmitted audio signal, i.
e.
his actual on-the air signal.
The advantage of hearing his on-the-air signal is that the pilot is made aware of any transmission problems, i.
e.
if there is no output from the transceiver, if the output is distorted, an unintentional transmission is occurring, etc.
In accordance with the present invention, a communications system that is used on board an aircraft is therefore described wherein the amplitude modulated radio frequency output of the aircraft transceiver is radiated by the antenna while simultaneously being sampled, demodulated and presented to the pilot's headphones.
In short, the present invention is comprised essentially of two parts, the pickup and the amplifier.
The pickup is placed in series with the transmission line where it samples any radio frequency signal, modulated or not, as it passes from the transceiver to the antenna.
The sampled signal is demodulated and fed to the amplifier.
The amplifier, which is placed in series with the pilot headphone jack, interrupts the audio flowing to the pilot headphones and allows the pilot to hear his own transmitted signal.
In the preferred embodiment, the pickup and the amplifier are connected by a single electrical cable.
