What is the minimum transmitter power level required by the FCC for a medium-frequency transmitter aboard a compulsorily fitted vessel?

The minimum transmitter power level required by the FCC for a medium-frequency transmitter aboard a compulsorily fitted vessel is defined as at least 60 watts PEP (Peak Envelope Power). This standard is set to ensure that vessels are equipped with sufficient power for reliable communication, which is critical for safety and emergency operations at sea.

Medium-frequency communication, particularly for maritime applications, often operates in the range of 300 kHz to 3 MHz, with 2182 kHz being a significant frequency for distress messages. The rationale for the 60 watts PEP requirement is based on the need to maintain effective communication with coast stations under various conditions and distances. By specifying a minimum power level, the FCC helps ensure that vessels can transmit clearly and consistently, which is vital for navigation safety and emergency response.

In contrast, other options refer either to specific technical configurations or power levels that do not align with official requirements. For example, A mentions 100 watts and highlights a single-sideband configuration, which isn't the general requirement across the board. C refers specifically to communication capability with the nearest public coast station rather than establishing a standardized power level. Lastly, D specifies a particular voltage and resistance scenario that doesn't align with the overall regulation concerning minimum power levels for maritime
