Description
The TY77 RC Master is a professional-grade universal remote control programmer, signal analyzer, and frequency detector — designed for locksmiths, RF technicians, and after-market installers who need a single bench tool to read, decode, copy, and re-broadcast across 280–868 MHz RF protocols.
Unlike single-frequency cloners, the TY77 integrates three independent tool paths on one board: frequency detection (250 MHz – 920 MHz sweep), protocol decoding (Fixed + Rolling + Custom), and signal re-broadcast (compatible with the major European / North American garage-door, gate, and alarm families). The 2.4″ colour LCD shows frequency, code length, modulation type, and timing in real time.
