Yep rtl-sdr. It's actually not attached to the system in the video. TBH it was low on the priorities list. When I originally got the pieces parts I plugged the rtl-sdr in and made sure it was "working" but when it needed a purpose built antenna and adapters and tuning - it suddenly became a back burner project. It also started mingling with antenna theory and proximity to the vhf and wifi antennas.
Its a good reminder though since now that I'm up and running it is easy to just plug it in and play with it. As I recall 2 miles was a basic distance with the stock mini-anntena. Evidently this was dissatisfying to AIS affecionatos but seems good enough for me. Also the AIS guys were quite passionate about having a class A vs B? One only sends your info and one sends and receives. I've also heard about government regulations in the works which would require the use of AIS on vessels which were equipped...similar to the requirement to use radar and VHF if so equipped. I'm kinda a private sorta guy and while I don't mind passive systems which only receive, I do mind constantly transmitting my boat's name, location, and other details.
