Spent yesterday on Low-tech ship comms.
Started with listening to #morsecode on 17MHz from KPH. Then I changed channels to receive #WeFax on 7MHz.
Moving onto satellite systems: sent a test message via #GMDSS Sat-C (600 bps), and ended with 4 emails being sent in about 2 hours at 4800 baud using a satellite dialup connection (VSAT).
Good times.
