If you would like to try to build a little AIS receiver and you are located around the coast, read on.
SDR AIS Decoding using a cheap USB DVB-T Stick
Hi all, here is a little project for the tech savvy Venturer, Rover or Leader. This project will be of particular interest if you live near the coast. You can use a DVB-T STICK to build a low cost AIS Receiver. Full credit and thanks goes to the team from MarineTraffic.com … For more detail see: http://tinyurl.com/oo4r594
If you have not played with the AIS display provided by MarineTraffic.com this may be something new for your JOTA / JOTI station.
During the warmer months I run a smart phone app that puts me on the MarineTraffic.com map when on my little boat.. You may even spot our real yacht SwingShift around the bays or lakes. Enjoy! – Philip VK3JNI
