All-Band Radio
Approx construction cost US$32
No-frills, low-budget, easy-build, sensitive radio with ONE might call this a “dog” of a radio. It doesn't pretend to any finesse. It doesn’t have high fidelity sound. However, it has good coverage, and good sensitivity. Moreover, it is a robust design that, unlike many others, does not depend on daintily wound coils, obscure parts, or a carefully constructed antenna. Built in Cape Town, South Africa, the prototype All-Band Radio brought in a good many stations from all around the world – loud and clear. This included the BBC, the Voice of America, Radio China, Radio Iran, the Deutsche Welle, and many more besides. Well into the night, it even picked up local Australian stations on the medium waves.
