The Morse Code was developed by Samuel F.B. Morse in 1844. Even after almost 170 years, it is still used today. The code can be sent quickly over the telegraph, and is also useful for emergency signaling (SOS) with a radio, mirror, or flashlight. This card set details all of the morse codes for the alphabet, numbers and additional punctuation symbols.

This set of cards shows the code signal on the front and the respective letter, number or symbol on the reverse. They are an invaluable aid to help you master Morse Code.
