This review examines the intersection of amateur radio’s oldest tradition—Continuous Wave (CW)—and its newest frontier: Artificial Intelligence. As we move further into 2026, the shift from basic digital signal processing (DSP) to true neural-network-based CW assistance is reshaping how we approach the “original” digital mode.

In the old days of ham radio, predicting propagation felt a bit like reading tea leaves. You’d check the solar flux index, look at a static sunspot number, and cross your fingers that the 20-meter band was open to Europe. In 2026, the "guesswork" is officially over....

If you’ve spent any time on the 40-meter band during a solar storm, you know the "noise wall" is the ultimate enemy. Traditional Digital Signal Processing (DSP) has been our shield for decades, but it often leaves voices sounding like "watery" robots or "underwater"...

Artificial Intelligence is moving from a novelty to a core feature in transceivers. Neural Noise Reduction: New "AI-DSP" chips can now isolate a human voice from heavy static with almost eerie clarity. Unlike old DSP filters, these use machine learning models trained...
