Morse code, invented in the 19th century, is still a widely used method of conveying information, as is semaphore. A knowledge of Morse code is compulsory for the first grades of the Radio Amateurs Examination, and signallers in all branches of the services use it.

Morse code can be transmitted either visually, by way of a lamp or wig-wam system or audibly, by radio, whistling, or tapping. Semaphore messages can be conveyed by someone waving his arms, using flags, or via a mechanical system, like two railway signal arms.

This program covers all aspects of morse code transmission, with the sound version using the TV speakers.

Semaphore and the wig-wag system use chunky, but adequate graphic figures. Each system covers the basic code, and if you place a finger on the keyboard an audible or visual indication of the letter, number or symbol will be produced.

Although it is many years since I used morse code seriously, I would judge the speed of the messages at about 12 words per minute. This is an excellent program.
