The Redsun RP-2100 is a multi-band commercial radio. It has no SSB internal support. However, it has an IF AM output that allows the user to connect a BFO or a Down-Converter (455 KHz to 12 KHz) to provide SSB, DRM and other modes. In this video I am using the SI5351A signal generator controlled by Arduino to listening to 15 meters band (USB mode).
