Could you build this?
No Building a zero-dependency Software-Defined Radio (SDR) server in C++17 requires deep expertise in digital signal processing (DSP), radio hardware protocols, and high-performance streaming architecture.
What it would actually take: Developing FernSDR requires implementing real-time DSP pipelines (FFT, decimation, I/Q signal demodulation for AM/FM/SSB) from scratch in modern C++ with low latency and zero external dependencies. The author must interface directly with various SDR hardware drivers (RTL-SDR, HackRF, Airspy) over USB, package web-socket/WebRTC audio and waterfall streaming into a self-hosted HTTP server, and optimize buffer management to prevent audio dropouts on low-power devices.
