When the very first radios and telegraph traces were set into support, primarily the only way to connect was to use Morse code. The very first transmitters experienced particularly inefficient models by today’s standards, so this was far more a useful limitation than a selection. As the engineering developed there turned less and less purpose to use Morse to talk, but loads of newbie radio operators continue to use this mode which includes [Kevin] aka [KB9RLW] who has developed a circuit which can translate spoken Morse code into a broadcasted Morse radio sign.
The circuit works by feeding the sign from a microphone into an Arduino. The Arduino listens for a certain threshold and keys the radio when it detects a word staying spoken. Radio operators use the terms “dit” and “dah” for dots and dashes respectively, and the Arduino is not actually translating the terms so significantly as it is sending a signal for the duration of nevertheless very long just about every term usually takes to say. The software for the Arduino is supplied on the project’s GitHub web page as very well, and works by using a selection of techniques to make guaranteed the keyed sign is as thoroughly clean as possible.
[Kevin] mentions that this unit could be applied by any one who wishes to operate a radio in this manner who may possibly have issues employing a classic Morse vital and who doesn’t want to retrain their mind to use other available tools like a puff straw or a foot critical. The circuit is remarkably simple for what it does, and in the online video under it appears to be [Kevin] is obtaining a blast employing it. If you are however wanting to learn to “speak” Morse code, even though, choose a appear at this guide which goes into element about it.
Thanks to [Dragan] for the suggestion!
