In a world with near-ubiquitous adoption of mobile phones, the use of early 20th century radio technology might seem unusual. But it makes sense for a number of practical reasons. Shortwave radio is an old variant of what many people may remember as “AM” analogue radio, operating on low frequency radio waves to deliver audio services. Shortwave radio is far simpler than modern digital TV or telecommunications services: receivers are widely available (or can be built from spare electrical parts), and it works across long distances. In hostile environments, sometimes older, simpler technologies are more readily available, and can deliver a more reliable communications channel than more complex, modern alternatives.
