Hi Jeroen, This is a very interesting project. If there's anything I would change, I would add a more powerful CPU, capable of running some other applications, like chat, maps, email, pictures. Otherwise you could end up for example receiving a position report but no being able to plot it without an external computer. Have you considered using an SBC instead? Myself I am approaching this differently. I am pushing for a SDR solution but I lack the skills to design a good frontend with small dimensions. Components for ISM bands are plenty and cheap, not so for ham bands.
