Hi Steve,
and thank you so much. That is a lot more than expected!
Now I need to work my way through your nodes and see how you had things done. That will be the fun part 
Just deployed and noticed that you split into A/B in the chart. That is not necessary as I want the total amount of messages (A+B). In real life there are these two channels just for the purpose of providing more bandwidth. Imagine a main port like Hongkong or wherever with hundreds if not thousands of ships. Each one sending an AIS message every 3 to 30 seconds. For the receiver it doesn't matter whether it was from channel A or B.
Another thing I discovered is that both LEDs (red and green) stays lit with your flow. Not sure what's going on, but will look into it. edit: my fault. For debug purposes I disconnected the off function nodes...display works fine.
