Question: 1 / 470

Why is it important to know the duty cycle of the mode you are using when transmitting?

It influences the signal distortion

It affects the message clarity

Some modes have high duty cycles that could exceed the transmitter's average power rating

Understanding the duty cycle of the mode you are using when transmitting is crucial because some modes operate at higher duty cycles, which can potentially exceed the transmitter's average power rating. The duty cycle refers to the proportion of time a transmitter is actively transmitting during a given period.

When operating a mode with a high duty cycle, the transmitter generates heat and demands more power than it typically would during intermittent transmission. If this exceeds the average power handling capability of the transmitter, it can lead to overheating or damage, affecting both the transmission equipment and the quality of communication.

Being aware of the duty cycle helps operators manage their power output and ensure they are within safe operating limits for their equipment, promoting reliability and longevity.
