These are recordings made by Arthur Goodnow, W1DM (SK), of 500 kHz in the Summer of 1974. It is incredible to realise just how recently 500 kHz was a major artery of international maritime communication and morse code the lifeblood that pumped through it. When I was first studying to become a radio ham in 1991, the frequency was silent but there was still some HF CW left. Now all gone: “Appelait tous. C’est notre dernier cri avant notre silence éternel.”
