So even today you don't really know what the diode was that was used in the context of the simple radio. It is quite simple to learn... en.wikipedia.org

The basic instruments were a Water-based barometer, standard themometer, sling psychrometer and electric wind vane and Anemometer and the all important cloud identification chart.

But the best description is here... samstoybox.com

And you can also see the Atomic Energy Lab orau.org
