To read data.

The easyTRX3 is based on SOTDMA technologies. The Transceiver TRX3 scans for time slots and will block available slots for its own transmission. Other AIS Class B units are then informed that this time slot will be used for next transmission. Thanks to the strong radiated transmission power of 5 Watt and the speed transmission rate, the easyTRX3 will make your navigational work safer and faster. Esspecially for faster boats it will make your navigation much easier and safer.   The TRX3 is modular designed. This allows the easyTRX3 to meet future requirements like to be connected/ communicate for example with DVB-T2 and DAB + or 3G mobile phone.

This board works then as some kind of an antenna and amplifies the received DAB+ signals before forwarding it to the DAB+ receiver. The DAB+ board has no integrated splitter for DAB+. The DAB+ signals will not be received by the top of the mast VHF antenna and not be forwarded to the easyTRX3.
