If you think HF radio is old fashioned...
Not long before Portishead radio shut up shop (and before 11/9) I had their boss on the jump seat on a flight into Funchal. He said that on their maritime service they were still using morse code to talk to over 200 hundred ships worldwide! The reason being that the shipping companies had realised that an ex Russian Navy morse operator was much cheaper to employ than a Marconi trained voice operator.
