GMDSS FCC Element 7 Practice Test 2025 - Free Maritime Communication Practice Questions and Study Guide

The transmitting range of most NAVTEX stations falls within the category of typically 200-400 nautical miles (360-720 km). NAVTEX, which stands for Navigational Telex, provides maritime safety information and navigational warnings via a dedicated service that operates in the medium frequency band. This range is achievable due to the nature of the service and the technology used, which allows for a reliable broadcast of safety messages and weather information to vessels at sea.

While it is true that factors like the height of the transmitter, the atmospheric conditions, and the sea state can all affect the actual range, the average operational range of 200-400 nautical miles is considered standard. This range enhances the ability of vessels to receive important maritime information while they are navigating away from the coast.

The other options reflect ranges that either exceed normal expectations for NAVTEX transmissions or suggest limitations that do not apply to the system's operational capacity. For example, suggesting that the range is limited to 50-100 nautical miles would underestimate the effectiveness of NAVTEX, while claiming upward of 1000 nautical miles would imply an unrealistic range for receivers, especially during the daytime. Hence, the noted range of 200-400 nautical miles accurately captures the operational capabilities of
