TinySA Ultra+ sweeps from 100 kHz to 5.4 GHz on a touchscreen smaller than a phone, then doubles as a signal generator and vector analyser. It is the cult tool for finding rogue Wi-Fi, drone links, rogue microphones and out-of-band noise — lab-grade radio visibility for the price of a decent pair of headphones.
