SDR AIS available in OpenPlotter 2

[Przemek]

Hi, when I install openplotter in my ubuntu laptop I see only GPS (/dev/ttyACM1) in Serial app. I open SDR VHF app, make calibration and after all process openplotter add automatic connection to my signalK server.

Regards Przemek

Hello Przemek

This is normal, only GPS is an serial Port.
The SDR-RTL Communication goes per Network with some help on translating the internal Audiosignal 
to NMEA ASCII Strings. The normal RTL-SDR Sticks have no Serial Port.

But there are other AIS-Receiver available, who do this, they have an Serial Port with the AIS Data.

PS: I also use these Sticks from NOOELEC
