What can lead to frequency interference?

Frequency interference can occur when signals overlap or disrupt one another, which is often the result of poor conditions and improper use. Poor conditions may include physical obstacles, atmospheric conditions, or environmental factors that can degrade the clarity and strength of a signal. Additionally, improper use—such as operating on the wrong frequency, poor equipment setup, or non-compliance with prescribed operational procedures—can contribute significantly to frequency interference. Thus, ensuring that frequencies are used correctly and under the right conditions is crucial to maintaining clear and reliable communication.

In contrast, the other options involve practices that generally help to prevent interference: authorized frequencies are designated to minimize overlap, effective modulation techniques enhance signal clarity, and regular maintenance ensures that equipment functions optimally. Each of these practices contributes to reducing the likelihood of frequency interference rather than causing it.
