Send Morse Code Messages With Your Very Own Code Oscillator

Perhaps you're an electronics junkie enraptured by images of spies and aviators sending secret messages to one another in Morse code. Perhaps you are a professional who simply desires an efficient and effective means of transmitting messages electronically. In either case, a code oscillator might just be what you're looking for, and you can find a variety of code oscillators on eBay.

A code oscillator is an electronic device that enables you to send out electronic signals which can then be picked up by other electronic devices. The electronic signals are of a special type, however, because they are in Morse code. Morse code is a telecommunications encoding scheme that represents characters of text as different sequences of signals of differing durations. The different signal durations are called dots and dashes, respectively, and so each character is encoded as a given sequence of dots and dashes. An oscillator, therefore, allows you to transmit messages in Morse code.

Even though Morse code has roots dating back all the way to the 1830s, it's still in use now among amateur radio and electronics enthusiasts, as well as by professionals in the fields of aeronautics and aviation. A code oscillator can efficiently transmit messages in Morse code as long as the one using the oscillator has been trained properly. This ease and efficiency of communication make code oscillators widespread not only among jet pilots and aviators but also among those who just enjoy tinkering with machines and electronic equipment. A code oscillator is still a good way to send messages to others, and so people still use them to send messages.

All across eBay, you can find a wide range of different types of code oscillators. Sometimes, you'll simply find stand-alone oscillators that have a power button, a power jack, knobs with which to regulate your signal and a button that you push to send out pulses in Morse code. Other times, you'll see a more complicated set that includes things like a radio receiver and perhaps some additional electronic components for maintenance purposes in case something malfunctions. Sometimes, you'll find a full-fledged device, encased in a plastic or metal cover, and other times, you'll find a bare-bones chip with something like a volume knob and speakers directly attached.
