@@chicken : Actually I have some experience with SMD/BGA soldering, and that's why I asked about DIY kit ;-) If you'd like to share with your spare parts please let me know so we can determine all the necessary costs.
Really impressive project @@chicken !
I live close to the port, so I think I could be able to receive the AIS signal. Did you considered about selling the PCB and parts for building own receiver? If so, I'd be interested for buying a DIY kit.
