Thank you to Paul Maine for writing in and sharing his latest tutorial video, which explains how Single Sideband (SSB) modulation works. In the video, Paul explains the concept and mathematical principles behind SSB by showing how to create an SSB receiver using GNU Radio and an RTL-SDR.

Paul Maine “ The SDR Guy” recently released a video about Single Side Band (SSB). 

The SDR Guy shows how to create a single sideband receiver using GNU Radio and an RTL-SDR. He also shows how to modulate SSB signals. Paul collaborated with Gary Schafer in the production of this video. Gary has created a must read blog post on SSB.

Paul answers the question: What is SSB and what’s the advantage when compared to Amplitude Modulation. He used SDR++ to capture an IQ file using an RTL-SDR and his HF antenna and is included in his resources. This allows you to use the resources he has provided to demodulate SSB even if you don’t have an HF antenna.

In fact, you don’t even need to have an SDR. A GitHub link is provided in the video description to all flowgraphs and IQ files discussed in the video. Lastly, The SDR Guy has included a complete Upper and Lower Side Band receiver that’s implemented in GNU Radio using an RTL-SDR!

Be sure to look at his YouTube Channel (paulmaine6433). He has many other SDR related videos.
