Eighty years ago this month, someone wrote in to the January 1941 issue of Radio & Television
magazine requesting plans for a one-tube set which would cover the broadcast bands and the shortwaves. The editors obliged with this simple circuit.

Coil winding data was included, and the editors noted that with the capacitor shown, one coil would cover the entire broadcast band. On the shortwaves, they noted that tuning would be very sharp, and recommended a smaller bandspread capacitor in parallel with the main tuning.
