Today at the Macedon Ranges Amateur Radio Club coffee morning, Eric, VK3EJD, brought along a new gadget that he hopes will remove noise he experiences from a neighbour's solar system.
I used to have a noise reducing speaker from BHI but was never terribly happy with it. He reminded me that I'd started building a live noise reduction application for macOS using RNNoise so when I got home I did some tinkering and got it working. Here's a demo - although the noise is not terribly bad. (I switch it in and out during the video.
Here's an example of removing solar panel noise from an AM transmission:
It's promising but needs to be trained for your specific noise. In this I'm using the default model. This runs easily on an Apple M4. I wonder when we'll start to see this built in to amateur radio gear?
