# Kenwood KNS: documenting ARCP-590G radio communication

> Kenwood KNS documents the ARCP-590G client's communication with a TS-590SG radio over serial and KNS TCP connections. The investigation compares Wireshark captures with CAT commands and records UTF-16LE encoding, connection sequences, cleartext authentication, and keepalive traffic.
