What is a symptom of RF feedback in a transmitter or transceiver?

• A. Strong signal strength reports
• B. Loss of connection
• C. Reports of garbled, distorted, or unintelligible voice transmissions
• D. Clear audio transmission

Answer: (C)

RF feedback in a transmitter or transceiver typically results in reports of garbled, distorted, or unintelligible voice transmissions. This occurs when radio frequency energy from the transmitter is inadvertently fed back into the microphone or audio processing stages, creating interference that degrades the clarity of the transmitted signal. The distortion may be perceived by others receiving the transmission, leading them to report that the audio is not clear.

Strong signal strength reports may indicate that the transmitter is functioning well in terms of power output, but it doesn't provide any information about the audio quality or any feedback issues. Loss of connection could indicate issues like equipment malfunction or interference, but it is not a direct symptom of RF feedback. Clear audio transmission suggests that the system is operating correctly without any distortion or feedback, which is the opposite of what happens with RF feedback. Thus, the correct identification of garbled or distorted transmissions as a symptom provides a clear indication of RF feedback affecting the quality of the transmitted signal.
