CwGet v2.55 is a software application for amateur radio operators designed to decode Morse code (CW) signals into text using a standard computer sound card, eliminating the need for specialized hardware. The program features a customizable interface with a spectrum display for visualizing signal frequencies and peaks, an oscillogram for monitoring signal presence and setting detection thresholds, and a received symbols window for displaying decoded text. Key functionalities include Automatic Frequency Control (AFC) to lock onto signals, adjustable FIR and IIR filters for noise reduction, and a burst filter to mitigate short noise impulses. It also supports automatic CW speed detection, multiple character sets, and the ability to record and replay received audio. Integration with logging software like AALog is facilitated through double-click word transfer, and transceiver frequency control is possible via the Omni-Rig interface, allowing for automatic tuning of the radio's VFO or RIT. The multi-channel decoder feature can simultaneously decode up to five strong signals within a 1600 Hz bandwidth, displayed in a separate Multi-RX Window with an adjustable squelch. CwGet also offers the capability to decode signals from pre-recorded WAVE files and can function as a narrow-band sound DSP filter for aural decoding. This is a commercial version and it has been tested on latest MS Winows versions.

CW Decoder provides a robust solution for amateur radio operators aiming to decode Morse code directly on their computer. The software processes incoming audio, presenting the decoded CW as text on the screen, which can be particularly useful during crowded band conditions or for those refining their copying skills. Additionally, it offers the capability to generate a sidetone, allowing operators to monitor the decoded audio in real-time. The application features a **spectrum display** of the audio input, complete with a sliding cursor. This visual aid enables precise selection of a specific audio frequency for decoding, helping to isolate desired signals from QRM. My field experience with similar decoders confirms that a clear visual representation of the signal greatly improves decoding accuracy, especially when dealing with weak signals or multiple stations. Beyond decoding, the program integrates a **keying function**, allowing users to transmit CW directly from their keyboard. This feature supports full CW break-in operation, which is essential for efficient contesting and DXing, providing immediate switching between transmit and receive modes without manual intervention.
