We've all been there: the radio is installed in the corner of the navigation unit, but a microphone at the helm would be much more practical for communicating with the lock. The X100 from Em-Trak solves this problem by using an app to turn any smartphone or smartwatch into a radio microphone. An AIS transponder is also on board.
The Connect-X app for iOS and Android turns smartphones and smartwatches into wireless steering microphones for the X100. Users can make and receive radio calls from any position on board, monitor VHF/DSC communication, track AIS traffic and receive navigation alerts. The system integrates with the on-board WLAN.
At the same time, the X100 offers private crew intercom between all connected Connect-X devices. This function works independently of the VHF radio and is designed to enable smooth internal communication without occupying the radio channels. In the event of MOB alarms or AIS-PLB signals, all connected mobile devices receive immediate warning messages including rescue instructions.
The X100 contains a class B AIS transceiver with five watts of transmission power that operates using the modern SOTDMA method. A mute mode with automatic timer allows the AIS transmission to be switched off temporarily, for example during anchor manoeuvres in crowded bays. The system has a lossless VHF antenna splitter so that one antenna can be used for both AIS and VHF.
The DSC functionality includes safety, urgency and distress calls as well as direct dialling communication with AIS targets. A standardised phone book combines DSC, AIS and intercom contacts. The X100 streams AIS data to navigation apps and supports NMEA 2000 and NMEA 0183 for connection to chart plotters and other on-board systems.
The X100 uses a clear-wave digital audio system for voice transmission, which, according to the manufacturer, should ensure clear communication even in high ambient noise levels. The internal loudspeaker delivers five watts of output power; external loudspeakers or a megaphone system with 15 watts can be connected as an option. The full-colour display should be readable in sunlight and the controls should also be operable with gloves or in wet conditions. The Em-Trak X100 is available in Germany from Ferropilot and costs around 1,900 euros.
