KaliAssistant/rpi-sdr-tx

rpi-sdr-tx is a utility toolkit built primarily as a wrapper around the well-known 'rpitx' library. While it provides a convenient interface for security researchers and hobbyists, it lacks a technical moat. The core innovation of using the Raspberry Pi's fractional-N divider in its hardware clock to emit RF was pioneered by Evariste F5OEO; this project is a functional repackaging for the Kali Linux / pentesting demographic. With 88 stars and low fork activity, it has modest traction but competes in a crowded niche of 'hardware hack' repos. The defensibility is low because it relies on specific, undocumented hardware quirks of the Broadcom SoC used in RPis, which are subject to change in newer hardware revisions (e.g., Pi 5). Frontier labs have zero interest in this space, as it is a niche hardware exploitation technique. The primary risk is maintenance fatigue and the project becoming obsolete as RPi hardware evolves or OS kernels tighten access to raw hardware registers (e.g., through the shift to gpiod/libgpiod).
