Subelement T7, PRACTICAL CIRCUITS· Group T7B
Which of the following actions should you take if a neighbor tells you that your station’s transmissions are interfering with their radio or TV reception?
- A.Make sure that your station is functioning properly and that it does not cause interference to your own radio or television when it is tuned to the same channel (correct answer)
- B.Immediately turn off your transmitter and contact the nearest FCC office for assistance
- C.Install a harmonic doubler on the output of your transmitter and tune it until the interference is eliminated
- D.All these choices are correct
WhyIf a neighbor reports interference from your station's transmissions, you should make sure your station is functioning properly and isn't causing interference to your own radio or television when it's tuned to the same channel. The first responsible step is to confirm your own station isn't at fault, checking that it doesn't cause the same kind of interference to your own radio or television when it's tuned to the same channel, answer A. Shutting down and calling the FCC (B) skips that basic troubleshooting step, and installing a "harmonic doubler" (C) is a nonsensical, invented device that would make interference worse, not better, so D, which includes that option, is also wrong.
