![]() ![]() I think there are naturally small timing variances and imperfections in anything sent by hand that the brain of an experienced ham sees right through but totally trips up the computer. If you are receiving computer-generated code it is great but they positively suck at hand-generated morse. I don’t know about this Arduino based decoder but I have tried a lot of different soundcard/computer software based ones. Most of the morse actually found on the radio is sent by hand. “today, its trivial to send and receive morse with any kind of processor.” working professionals who happened to be hams could do that, but even the most techie ham who was not working in the field would not be messing around with controllers and such. in the 70’s, though, it was very rare to find hams that knew about controllers and were able to build morse decoders. Today, its trivial to send and receive morse with any kind of processor. did I mention, it only had a single char display? ) but for 1970’s, that was still pretty amazing. he bought an ‘A-tronix’ brand code reader that would clamp onto the speaker-out of your ham rig and you’d adjust the volume level on the code reader along with a ‘guessed bit rate’ and it would try to decode each letter and show a single letter on its single letter display. I could send and receive morse (I was a teen at the time) but my father could not seem to be able to pick it up. could never deal with the mechanical bug.

Or, you can check out some other Morse-based projects. Once you learn how to read Morse code, you might want to teach your Arduino to understand it, too. You can see the project in operation in the video below. The device acts like an old commercial model, the Datong D70, although it can optionally accept an LCD screen, something the D70 didn’t have. wanted a device to generate practice code, so he built it around an Arduino. The state of the art today employs a computer to randomly generate practice text. In the old days, you usually learned Morse code from an experienced sender, by listening to the radio, or from an audio tape. If you know Morse code, you could privately talk to a concealed computer on just two I/O lines. Finally, Morse code is a very simple way to do covert communications. Morse code can be sent using low power, equipment built from simple materials or even using mirrors or flashlights. ![]() Another reason is that Morse code can often get through when other human-readable schemes fail. First, some people actually enjoy it either for the nostalgia or the challenge of it. There are, however, at least three reasons you might want to learn it anyway. You don’t need it for a ham license anymore. You may wonder why anyone would want to learn Morse code. ![]()
