Here in Ann Arbor, I’m working to establish a permanent amateur radio station at the Hands-On Museum. As part of this station, I wanted to have some kind of “hands-on” activity. 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. 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.
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. Even so, I’m thinking about trying it.
Googling around for computers programs that can copy Morse Code, I found the following. Except where noted, these programs run on PCs:
- CWGet. $30. This program seems to have a lot of users.
- WD6CNF Morse Decoder. Freeware. Since this one is free, I think I’ll try this one first.
- MRP40. 50 euros.
- RadioRaft. There is both a free version and a commercial version of this program. The website includes a simple circuit for interfacing a receiver’s audio output to a computer’s serial interface.
- MultiMode. $39-up. This program runs on the Mac.
In addition to these programs, I also found this article that describes a stand-alone CW decoder based on a PIC processor.
