QSL from 50 years ago.... this is was a utility station on Guam, making regular transmissions on SSB across the Pacific to San Francisco, using 15 kW. This particular signal kept right on going, reaching Cape Town, some 15000 miles away or nearly 26000 km! That's more than halfway around the world, which is pretty distant even for shortwave. It's a form letter with all the relevant info but the Engineer added a paragraph about this particular transmission. Guam was in the news recently when North Korea announced it might send a missile to land in the waters just a few miles offshore. Not a nice thought, and perhaps a reason for Trump to engage directly with Kim. A long-term view on the Korea's is that they should merge, as did Vietnam, now one of the most dynamic economies in the world. It's possible. Recently, South Korea's president Moon visited Mt Paektu on the North Korean-Chinese border, a place sacred to both Korea's. The hope is that enough Koreans will continue to see themselves as that, given their long history. It would allow the US to take some military chips off the table, or move them. For China it would mean a complicating shuffle in the region.
