 A terminal-based RF signal analysis tool for capturing, decoding, and retransmitting automotive keyfob signals. Built in Rust with a real-time TUI powered by `ratatui`. Protocol decoders are aligned with the [ProtoPirate](REFERENCES/ProtoPirate/) reference.
 
-**Supported hardware:** KAT uses **HackRF One** (or compatible) when present for full receive and transmit. If no HackRF is found, it will use an **RTL-SDR** (e.g. RTL433-style dongles) for **receive-only** capture and decode; transmit (Lock/Unlock/Trunk/Panic, Replay) is disabled when using RTL-SDR.
+**Supported hardware:** KAT uses **HackRF One** (or compatible) when present for full receive and transmit. For **receive-only** operation, **RTL433** (or any compatible RTL-SDR dongle) is supported: if no HackRF is found, KAT uses the first available RTL-SDR for capture and decode; transmit (Lock/Unlock/Trunk/Panic, Replay) is disabled when using RTL433/RTL-SDR.

-KAT starts in an interactive terminal UI. If no HackRF or RTL-SDR is detected, a warning appears (“No HackRF or RTL-SDR detected”) and you can press any key to continue without TX/RX support—you can still view, import, and export captures. The header shows the active device (**HackRF**, **RTL-SDR (RX only)**, or **No device**) and radio status; when no device is connected, the status is shown in red (DISCONNECTED). When using RTL-SDR, transmit actions (Replay, TX Lock/Unlock/Trunk/Panic) show “(no TX)” in the signal menu and display a receive-only message if selected.
