In the April 2022 edition of Wireless, we look at the part of the radio spectrum called shortwave, consider its importance in the past and continued relevance in a digital world. Founder of the SWLing blog Thomas Witherspoon discusses the historical development of shortwave, including its heyday during the Cold War, and explains how it continues to be used today, for instance to evade Russian internet censorship during the Ukrainian war. The programme also remembers Irish pirate shortwave operators of the 1980s as featured on our related site Pirate.ie.
