Ham Radio SSB Processor with AVR Microcontroller

Gregory demonstrates the Ham Radio Baseband Speech processor, developed in the last video with an AVR microcontroller, on the bench, showing its behavior for different input frequencies in the audio range. The IQ zero-if baseband audio signal is recorded as an LR audio file and Octave is used to reverse the process, up converting it to the original audible range, proving the design works. Video showing the project design:    • DSP Baseband Speech Processor for ham...   The DSP runs on an AVR ATtmega164 microcontroller and implements all the processing stack in C++. This device will be used as a baseband processor for SSB transmission, where direct SSB generation is accomplished by quadrature up conversion.
