How to build
If you wanted to buy a radio receiver in the
twenties, you could not just go to the nearest radio shop and buy one. The radio
shops was far apart and if you found one in many cases the price upset all
plans.
An alternative was to build the receiver yourself. Before starting this project,
in many cases one had to buy an instruction in how to do.
I have put an instruction on how to build a super-heterodyne receiver on this
site, but the principles are the same whether it is such a fine receiver or a
simple two valves. Included with the book are two blueprints so big it was not
possible to make a copy.

If you wanted to experiment with radio you could buy a magazine with diagrams like this Radio Flash from 1922:
