Could you build this?
No Building a software-defined radio transceiver on an ESP32 requires deep expertise in digital signal processing (DSP), RF design, real-time embedded C/assembly, and hardware timing.
What it would actually take: Requires low-level ESP32-S3 firmware written in C/C++ or ESP-IDF utilizing direct I2S/DMA transfers, SPI radio control, and custom DSP algorithms for modulation (FM/SSB) and IQ demodulation. It interfaces with RF front-end hardware and implements the rtl_tcp network protocol for software interoperability. Key expertise involves embedded systems engineering, discrete radio frequency electronics, and algorithmic digital signal processing.
