I have a large AIS network installed in the inland waterways and want to add voice monitoring. Currently using a AIS radio recievers(sr161's), and lantronix boxes. I would like to add channel 16 monitoring through the extra serial port in the lantronix box but dont think it will be possible. These boxes might be better suited??
They have dual ADC converters, ARM processors that can encode the audio into MP3, and would hopefully be able to scan 161 and 162 for AIS and monitor channel 16. It would reuire scrapping the curent 500 stations, but being able to use the same antenna's and network connection etc would make it an easy box swap hopefully.
