I will describe the basics of shortwave listening - a hobby of listening to shortwave radio broadcasts between 1700 kHz and 30 MHz.
I’ll explain how to get an SWL sign for yourself, join contests, apps you could use to report your evidence for a listened radio exchange, and list many links to learn more and why this is a great hobby.
Then I’ll move to the next part of the article and describe the basics of an SDR[1] dongle (I believe most of them are not open hardware, I am not sure this is allowed at the Magazine), what kind of hardware you can purchase and what kind of open source software you could use to get started on Fedora Linux.
[1] A software-defined radio (SDR) system is a radio communication system that uses software for the modulation and demodulation of radio signals.
