CW Decoder

CW Decoder is a handy application that makes it easy to view and display continuous waves. These waveforms are crucial for carrying information, with Morse code being a prime example!

Understanding the Interface

The interface of CW Decoder isn’t super fancy, especially if you’re new to this kind of app. If you find yourself scratching your head, don’t worry! Just take some time to read through the help manual step by step to get the hang of all the buttons, sliders, and options.

Features and Display Modes

This application can show a graphical spectrum, along with text, signal strength, code status, WPM counters, and even an overload indicator for the input signal. You can pick between two display modes: line or waterfall. Plus, you have options to set threshold levels for the signal and choose from auto, quiet, noisy, or manual settings.

Audio Filtering Capabilities

Since CW Decoder processes sound signals, it comes with an audio filter that uses a noise reduction algorithm. When this feature is turned on, it might use up some system resources—but don’t stress! This mostly affects computers with processors under 300 MHz.

Text Features

The app translates signals into text and has a scrollable text window where you can adjust the text size. And guess what? You can save that text as a TXT file whenever you need!

Operating Modes

CW Decoder works in three different modes. The first one is ‘Scan’ mode which lets the app function as a spectrum analyzer with a neat graphical display. In manual mode, it acts like a decoder where you can type your own text. Finally, there’s decoding mode that translates CW into readable text.

Data Transmission

This software also allows data transmission using a COM port and helps synchronize receiving speed. Pretty cool right?

Final Thoughts on CW Decoder

In summary, CW Decoder is a reliable tool if you're looking to decode or encode messages sent using continuous wave signals!
