In 2007, the Five Star DXers Association, FSDXA, organized a large DXpedition to St. Brandon Island in the Indian Ocean. This DXpedition still rates as the most successful ever in terms of the number of contacts during an absolute sunspot minimum. The call sign, 3B7C, was for three intense weeks in September 2007, synonymous with global fellowship and heartfelt joy that is so typical among large numbers of ham radio operators all over the world, as they shared the best hobby of them all – ...

Being part of a major radio DXpedition is very special. It is as much fun to provide a unique DX or IOTA contact as it is for the DX-IOTA chaser to receive it. It is exciting to sit in front of the transceiver and listen to the vast and endless pile-ups. It is satisfying to be able to provide radio amateurs with each hard fought contact. To be the hunted DX is incomparable and very rewarding and hopefully every radio amateur will, at least once in his or her lifetime, get the opportunity t...

A "riveting and thoroughly researched" history of language technology's effect on society across millennia—from Sumerian syntax to social media hashtags (Phil Lapsley).Writing was born thousands of years ago in Mesopotamia. Spreading to Sumer, and then Egypt, this revolutionary tool allowed rulers to extend their control far and wide, giving rise to the world's first empires. When Phoenician traders took their alphabet to Greece, literacy's first boom led to the bi...
