Funny thing is, when I thought about how to make AIS available fot
jotties,
my idea was to have a simple VHF receiver connected to a computer through
a
modem, to enable the average jottie to receive the AIS signals from big
ships to avoid.

I'm building my own, it's not so complicated and the protocol is
publicly available.

There are ICs for GMSK modulation, just add a simple VHF receiver, a
microcontroller and some software.

Now you're talking :-). I haven't had the time yet to do a thourough search.
So I would like to ask you: where did you find a good clear source of the
protocol and what GMSK IC are you using?
