It can decode Morse code signals received on a radio at up to 50 words per minute, and it can transmit Morse code tapped out on your keyboard, keying a radio transmitter button via the PC's serial port. Which brings us to CW Decoder, a free application from WD6CNF.
The Internet uses the same basic technology, and probably the same wires, too, in some places, so it's appropriate that we should take a look at software for sending and receiving Morse code via a PC. Known by the shorthand CW, Morse code is a direct ancestor of computer code.
Most people know what Morse code is, too: Named for its inventor, it's the dots and dashes that the telegraph man so dramatically taps out on a metal key in old Western movies. OK, Computeers! What's the oldest form of electronic communication? If you said the telegraph, you're right.
