[Elecraft] pow radio

[William E. Twaddell]

The razor blade radio regionally appeared in either Popular Science or 
Popular Mechanics in the early 1940's.
It was appropriately named the "Oatmeal Box" radio as you used a Quaker 
Oats box to wind the coil.
I built one and used it to copy many radio stations as the coil had taps 
to change resonance.
I used Lionel phones , a safety pin and a long wire out the window.
