What is the frequency of JRC NCR-333?

The JRC NCR-333 is a NAVTEX receiver that is capable of tuning into three specific frequencies: 490 kHz, 518 kHz, and 4209.5 kHz. These frequencies are dedicated to broadcasting NAVTEX messages, which are essential for marine navigation. NAVTEX stands for Navigational Telex and is a system that transmits navigational and meteorological warnings, search and rescue information, and other critical messages to ships at sea. The JRC NCR-333 is designed to receive these broadcasts and display the information on a clear and easy-to-read 5.7-inch LCD screen. This allows mariners to stay informed and make informed decisions while navigating the open waters. The ability to receive and display NAVTEX messages is crucial for the safety and efficiency of marine operations.
