Audel's Handy Book of Practical Electricity
My grandfather, Roland (my middle name) Somers, on my mother's side was a residential
(aka house) builder. He owned and operated a small (2-3 employees) business in
Mayo, Maryland in the middle of the last century. Being his
only grandson, I got what survived of his books like this
Audel's Handy Book of Practical Electricity,
c1942, by Theo. udel & Co. Publishers. I also have
a couple of his carpentry and hand tool books of the era.
The scanned page below is titled, "List of Abbreviations to Be Used Radio Communication,"
as dictated by the
International Radiotelegraphic Convention (IRC).
Amateur radio operators will recognize the list as being a collection of the familiar
"Q" Signals, although stated in sometimes archaic prose; e.g., QRN = "Are the atmospherics
strong?" and QSB = "Is my spark bad?"
The book is filled with good information on motors and generators, switching
and control circuits, electrical theory, and other stuff still valid today. The
section on knob-and-tube wiring can probably be skipped.
I used to see that stuff in turn-of-the-20th century houses when working as an electrician
back in the 1970s.
