I was "intimately" involved with HF military communications, working
transatlantic and transpacific paths using a variety of log periodic,
inverted discone and rhombic antennas and either 10 kw or 45 kw
transmitters from 1968-1970. The station was in operation 24/7 but I
generally pulled eight hour shifts...
