Just a few decades ago, getting into hobby radio meant lots of specialty hardware, and making changes to your setup to work on various frequencies wasn’t particularly easy. Since software-defined radio (SDR) came onto the scene in an accessible way for most of us, this barrier to entry was reduced …read more
Nary a month since NASA managed to reboot Voyager 2 after a technical malfunction, it looks like we’re about to lose contact for almost a whole year. The radio antenna that acts as Earth’s sole transmitter to Voyager 2 will soon undergo important upgra… Continue reading NASA is about to stop talking to Voyager 2 for almost a year
For some reason, of all the ships that have sailed the oceans, it’s the unlucky ones that capture our imagination. Few ships have been as unlucky as the RMS Titanic, sinking as she did on the night of April 15, 1912 after raking across an iceberg on her maiden …read more
