Morse Code Keyboard

The Morse Code Keyboard allows you to transmit at a speed of 40 to 206 PARIS (characters per minute, e.g.: 8 to 41 words per minute). It contains 10 memories; in the first one, you can store 46 characters, in each of the others, up to 22 characters. The memory contents can be stored for a long time. The inner buffer has a capacity for 64 characters. The speed after start up is 100 PARIS (20 wpm).

Mechanical performance
The Morse Code Keyboard is built as a portable unit - it is small, light weight and has a low energy consumption. It takes up only 1/4 of the space of a standard PC keyboard. Two metal strips allow you to easily transport it. The push-buttons (the keys) are a discrete type from an old PC, with conductive India-rubber. The instrument is very thin, as can be seen from a side view. The printed circuit board is mounted under the keyboard in a small tin box. Two connectors, supply and keying are located on the side.
