I believe all ships I’ve sailed had HF radio. The newer generation of HF (high freq) radio are pretty straight forward to utilize but one still has to know about frequency utilization if it is not automated which few are outside the military.
The pre digital HF equipment… I don’t think i ever saw it used even by the IT guys, more likely no one really understood it.
