DroidNavtex decodes NAVTEX messages from your receiver through the Android phone or tablets microphone or through a connected interface.

Get your copy of DroidNavtex today, and never be without up to date marine weather information and marine warnings again..

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).
You need to have a receiver which can receive 518KHz or 490KHz SSB to use this app!!
Special audio filters even decode very weak signals through the microphone and make DroidNavtex a very affordable alternative to high priced decoders.



An “Auto mode” finds the frequency and the sideband of the Navtex signal automatically. With “Auto mode” turned off the frequency and sideband can be adjusted manually.
A built-in database stores the received messages which can then be filtered, sorted and shared. Messages can be deleted individually, in groups or by age.
To save battery power 7 timers can be set to start DroidNavtex at a given time to decode messages. All timers can be set in local time or UTC.

Excellent little utility

I mainly charter sailing boats and I have yet to encounter a charter boat with navtex. Receiving weather forecasts while at sea in remote parts of the world can be exceptionally difficult. This little utility will give me access to English language forecasts worldwide via my very old Sony ICF7600. I have only tried this utility at home a couple of hundred miles from the nearest transmitter but despite a really scratchy signal, this utility locked on and translated it to text. Very impressive.

A well thought out product

Easily decodes Navtex with magic auto mode.Handles weak signals well. Messages are easily managed in the database. Just need a ssb radio say a Sony 7600. Well worth the price of 3 coffees.

An excellent product

Installed on Samsung Galaxy SII and Asus Transformer TF101. A pleasure to use. The autotune function is the best I have seen, locking onto the signal in fractions of a second and at very low signal levels. Radios used – Sony ICF-SW100 and Sony ICF-SW7600.
