What is it
Dual-channel AIS reception at 161.975 MHz and 162.025 MHz.
It is a real dual channel AIS decoder sharing NMEA message string via UDP.
The app uses a USB DVB-T dongle to decode VHF radio signals. It is working without internet connection.
The app is forwarding the decoded NMEA messages to 3rd party apps like BoatBeacon or OpenCPN.
What you see:
I start AIS share.
1st connection is set to localhost 127.0.0.1 here i share to OpenCPN for android.
2st connection i send data to my iPad where also a App is receiving NMEA data.
3rd connection is my PC. Here i run OpenCPN for PC.

F A Q
I installed Martin Marinov RTL2832U driver app, do I need yours
YES, my driver app is tuned to AIS message receiption. AIS Share will not work without my driver app.
RTL AIS DRIVER app will not influence any other RTL SDR related app you have installed.
Many thanks to Harmen Meijer for testing and tips.
