NAVTEX

NAVTEX is an international automated medium frequency (518 kHz) direct-printing service for delivery of navigational and meteorological warnings and forecasts, as well as urgent marine safety information to ships. It was developed to provide a low-cost, simple, and automated means of receiving this information aboard ships at sea within approximately 200 nautical miles of shore. (source NOAA)

I already did some NAVTEX DXing in Europe, and since noise levels in my location are reasonably low on medium wave I decided to start scanning 518 kHz over here too. The software I use is Frisnit NAVTEX Decoder. There is a Java version, but the Windows version under Wine runs very well, if not better, on Linux.

Taiwan is located in area XI-B and the current schedule is here.
