Signal Corps Two-Element Alphabet

This table contains links to each letter of the alphabet for the two-element code.  Click on the letter you wish to see.  Each page contains an animated GIF file illustrating what each letter should look like if you were receiving a message from a distant signal station.

When you look at these animated GIF files, remember the elements are opposite of what they are when you are sending.  (i.e., a "1" is the flag being lowered to your right, a "2" is the flag being lowered to your left.)  Also, please note the letter will repeat after a short pause.
