1938 Two Tube Regen

1938SepRadioNews2Eighty five years ago this month, the September 1938 issue of Radio News carried detailed construction details for putting together this two-tube shortwave receiver. It used a 1B4 as regenerative detector, followed by a 1F4 as audio amplifier.

The set tuned 160 through 10 meters, and the author advised that the beginner should start on 160 meters, since most signals will be relatively local and easy to tune in. He also gave pointers on which bands would work best at different times of day.

The article concludes by noting that once the reader becomes acquainted with the operation of the set, it would be a reliable and consistent way to bring to your headphones most of the DX signals of the world.
