![]() ![]() In addition to these programs, I also found this article that describes a stand-alone CW decoder based on a PIC processor. The website includes a simple circuit for interfacing a receiver’s audio output to a computer’s serial interface. ![]() There is both a free version and a commercial version of this program. Since this one is free, I think I’ll try this one first. This program seems to have a lot of users. Except where noted, these programs run on PCs: Googling around for computers programs that can copy Morse Code, I found the following. Tech Note 078 - ESP32 Real Time Morse Decoder 5,417 views An ESP32 together with an OLED display and a basic microphone are used to decode in real-time Morse code. The problem, of course is that most computer programs are still not great at copying Morse Code, and what the kids send will probably be very choppy. I’m also thinking of setting up another display that will let kids tap out their names on a key while a computer tries to decipher what’s sent. One thing that came to mind is to have a computer set up to let kids type their names in to a computer and then have it spit it out in Morse Code. As part of this station, I wanted to have some kind of “hands-on” activity. Nevertheless, CW Decoder is unique, useful, and free, and we recommend it to anyone with an interest in Morse code or amateur radio.Here in Ann Arbor, I’m working to establish a permanent amateur radio station at the Hands-On Museum. chm files we feel this should be a problem for the developer, not the user. Same with syllables in I or E for short and A or O for long. There is also a luminous variant, the presence of a clignotant light for 2 distinct durations is a Morse code handle. Our only real gripe is the Help file, which won't open in some recent versions of Windows, such as 64-bit Windows 7, due to a known issue involving. Morse code is an auditive code, any long and short beep sounds, it can be Morse. However, the program did decode radio signals to text, and that's what we wanted it to do-it's up to you to configure it to your own system. After much fiddling, we managed to get a scrolling text display, though unfortunately not in readable English. If, like us, you don't happen to have a ham radio at hand, we recommend trying one of the many sites online for learning or using CW. New users will probably need some time to sort it all out it's actually quite a basic setup but with lots of options. Variable displays for signal-to-noise ratio, peak frequency, and other readouts run along the bottom of the interface. On the taskbar, there are menu items like AFC (Automatic Frequency Control) and Transmit, interface sliders for Rx Gain, Rx Coarse, Nx Blank, Tx Sync, and Squelch, and looping controls that are common in amateur radio components and software. Its hands-free operation means you don't have to stop keying to click the mouse.ĬW Decoder's colorful, feature-packed interface is a bit busy for our tastes, but its close resemblance to an amateur radio's faceplate will be familiar to many of the program's users, and many of the controls will be, too. 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.
