Partial The companion PC tools (spectrum and constellation viewers) and the ESP32 firmware for arbitrary IQ playback can be vibe-coded. Verifying the RF output actually meets spec, and transmitting legally, needs RF engineering knowledge and bench instruments.
What it would actually take: Write ESP32-S3 firmware that streams IQ samples from SRAM through the DAC or I2S path at selectable rates, plus host-side tools to generate QPSK and 16QAM OFDM waveforms and plot spectra. The hard part is the RF front end: matching output levels, filtering, and regulatory-compliant transmit power need a spectrum analyzer and an RF engineer to validate. Expect embedded C, DSP, and radio-regulation knowledge.
