I've just read "Text-book on Wireless Telegraphy" available to download 
here:  https://books.google.com/books?id=2a86AQAAMAAJ

This book was used by the Navy to train radio operators in 1914 and 
thoroughly documents the state of the art in electromagnetic physics and 
Marconi spark equipment.
I found it fascinating to journey back to the dawn of radio and see the 
rudimentary science known at that time. The Marconi equipment is 
thoroughly described including design theory, schematic circuit diagrams 
and proper operation and connection. I also located Navy documents that 
provides a detailed history of Navy wireless operations from its inception.

This little voyage into the past gave me a considerably better 
understanding of just what can be done with a 5KW spark station and 
crystal receiver.
