Which statement best describes the NACTEX filtering function?

• A. Automated weather forecast generation
• B. Prevents unwanted broadcasts by filtering at the receiver level
• C. Encrypts incoming messages
• D. Amplifies signals

Answer: (B)

Filtering is a receiver-side control that decides which incoming transmissions your equipment will process. The NACTEX filtering function specifically prevents unwanted broadcasts from being shown or heard by filtering at the receiver level, so you only receive the information you want. It isn’t about generating forecasts, encrypting messages, or boosting signal strength, which are separate functions handled by other parts of the system.
