What could be a result of improperly tuned equipment in amateur radio operation?

Stronger signal
Clear audio quality
Increased interference and poor transmission
Extended operational range

The correct answer is: Increased interference and poor transmission

Improperly tuned equipment in amateur radio can lead to increased interference and poor transmission. When a transmitter is not properly tuned, it can radiate signals outside of its intended frequency, which can cause interference with other communications. This means that the signals can merge with those from other devices, leading to degraded audio quality and clarity for both the user and those receiving the transmission. Additionally, an improperly tuned antenna system can result in poor radiation efficiency, which means that the radio waves are not being effectively transmitted in the desired direction. This could cause a smaller effective coverage area and noticeably impact the overall performance of the transmission. Proper tuning, on the other hand, helps to ensure optimal signal strength and clarity, reduce interference, and improve the overall quality of communication.
