Question 1 of 27070

Which of the following procedures may be used in many U.S. ports as a quick field test to determine if a shipboard VHF receiver is operating properly?

🔍 Key Concepts

• VHF marine band frequencies and which services typically use which parts of the band • Difference between marine traffic/USCG working channels and weather broadcast channels • What a simple, no‑equipment field test would look like in a harbor

💭 Think About

• Which option relies on a signal that you can reasonably expect to be present and strong in most U.S. ports, day and night, without coordination? • Which choices describe procedures that really test the receiver only, and which ones actually depend on the ship’s transmitter or special test gear? • Think about what frequencies are commonly used for continuous public broadcasts related to marine operations.

✅ Before You Answer

• Look up which service transmits on frequencies around 162 MHz and whether those signals are typically continuous in coastal areas • Check whether a simplex self‑check truly verifies receiver performance, or mainly checks the transmitter/side‑tone path • Notice which answer involves specialized test equipment, and ask if that still fits the idea of a “quick field test in many U.S. ports”

Question 1 of 27070

Which of the following procedures may be used in many U.S. ports as a quick field test to determine if a shipboard VHF receiver is operating properly?

Tune the VHF receiver to 158.6 MHz and listen for local U.S. Coast Guard announcements or radio traffic from other vessels.

Set the VHF radio to a simplex channel, key the transmitter, and monitor the quality of the transmitted signal with the internal receiver.

Tune the VHF radio to 162.550 MHz, 162.400 MHz or 162.475 MHz and listen for broadcasts from the National Oceanic and Atmospheric Administration .

Connect appropriate test equipment to the radio and measure signal levels at the output of the receiver's RF amplifier stage.
