What would cause a broadcast AM or FM radio to receive an amateur radio transmission unintentionally?
The receiver is unable to reject strong signals outside the AM or FM band✓Respuesta correcta
The microphone gain of the transmitter is turned up too high
The audio amplifier of the transmitter is overloaded
The deviation of an FM transmitter is set too low
Explicación
A broadcast receiver's front end is broad and its circuits can be driven nonlinear by any strong nearby signal, so a legal amateur transmission far outside the broadcast band still gets through. This is fundamental overload in the receiver, not a defect in the transmitter, which is why the transmitter-fault choices are wrong.
