I tinker with radios and write about what I find. Most of my work involves software-defined radio (SDR), signal analysis, and exploring how wireless protocols work at the physical layer.
Hardware I use regularly: BladeRF 2.0 micro xA4, HackRF One, RTL-SDR v3, various antennas.
Software: GNU Radio, gr-osmosdr, rtl_433, Wireshark, YateBTS, OpenBTS.
Everything here is receive-only research on publicly documented protocols. I do not assist with illegal interception or unauthorized transmission.
