NAVTEX Decoder

Decode NAVTEX marine weather transmissions on your Android device.

Are you on a ship? Do you need to be able to receive up to date weather and marine safety transmissions?

NAVTEX Decoder lets you view NAVTEX marine weather transmissions on your Android device. Just set it near a radio (or for better quality decoding, connect a cable from the radio's audio output jack to the microphone jack), tune in a NAVTEX frequency, and watch the transmissions.

NAVTEX weather and marine safety messages are transmitted from dozens of sites around the world. Now you can display these messages without buying a dedicated NAVTEX receiver.

Most NAVTEX transmissions are on 518 kHz. If you tune in to NAVTEX via USB mode, set your radio to 515.8 kHz USB, set the frequency in the app to 2200 Hz, turn off invert mode, and when the next scheduled transmission begins, NAVTEX pad will start decoding.
