Description
An HF receiver built on a piece of wood featuring a full rich audio response on CW and SSB with a tunable CW-SSB filter: Several modules make up the receiver: RP2350 Pico-2 microcontroller, AD9950 Direct Digital Synthesizer, ADAA1701-DSP 56-bit double-precision pro-audio grade processor, an AD831 strong-active 200 MHz mixer (zero overload). Headset and speaker amps. DC input 9-15V. Power consumption 3W.
Pico - Software: The authors goal was to write zero-code. Code to tune the synthesizer and display on color TFT display 100% written by AI using ChatGPT. First-time interesting experience.
DSP (audio) software. Graphical user interface of internal ADC-DACs, mixer, amps, and tunable filters.
A presentation would involve Power-Point, videos of operating, etc.
