This site contains several articles that focus on U.S. Telegraph-History.
The majority of these articles first appeared in the "Key and Telegraph"
column of "The AWA Journal," the quarterly magazine of the Antique Wireless Association (A non-profit historical society.)
These web versions have been expanded to include additional information, images and illustrations.
Some have evolved into comprehensive sites.
Other articles are original classic works by telegraph pioneers, engineers
and inventors.
Certain new articles will be added here in the future.
