There\u2019s an interesting and promising project that leverages AI to remove noise from radio audio signals\u2014including SSB and CW.<\/p>\n

The project is called RMnoise<\/b><\/span>, and it uses artificial intelligence trained to recognize desired<\/i> signals. Once trained, it can dramatically reduce background noise in received audio, making weak or difficult signals much easier to copy.<\/p>\n

You can learn more about the project here:<\/p>\n

https:\/\/ournetplace.com\/rm-noise\/<\/a><\/p>\n

And dive into the technical documentation here:<\/p>\n

https:\/\/ournetplace.com\/rm-noise\/documentation\/<\/a><\/p>\n

How It Works<\/b><\/h3>\n

In practical terms, RMnoise sits between your receiver and your ears using your computer\u2019s sound card. Audio from your radio is fed into the computer, where RMnoise processes it in real time. The AI attempts to suppress unwanted noise while preserving the signal of interest, then sends the cleaned-up audio back out through your computer\u2019s audio output.<\/p>\n

There are several demonstration videos\u2014with audio<\/i>\u2014that show how effective RMnoise can be with challenging signals:<\/p>\n

https:\/\/ournetplace.com\/rm-noise\/videos\/<\/a><\/p>\n

You Can Try It Yourself<\/b><\/h3>\n

Perhaps the most exciting part: you can try RMnoise right now<\/b><\/span>.<\/p>\n

It\u2019s simply a matter of installing a small program, configuring it to work with your computer\u2019s sound card, and routing audio from your receiver into the computer. RMnoise picks up the incoming audio, does its \u201cmagic,\u201d and outputs a noticeably cleaner signal.<\/p>\n

RMnoise is for anyone interested in experimenting with modern signal processing techniques.<\/p>\n
