DroidNavtex decodes NAVTEX messages from your receiver through your phones/tablets microphone or through a connected interface. Special audio filters even decode very weak signals through the microphone and make DroidNavtex a very affordable alternative to high priced decoders.
NAVTEX broadcasts worldwide on 518 kHz and 490 kHz using a data mode called SITOR-B (amateur radio (Ham Radio) operators might recognise it as AMTOR).
Get your copy of DrodiNavtex today, and never be without up to date marine weather information and marine warnings again..
You need to have a receiver which can receive 518KHz or 490KHz SSB to use this app!!
