Hytera PD785G Radio
The Hytera PD785G is a premium, rugged digital (DMR) and analog handheld two-way radio featuring a full keypad, LCD display, and GPS, designed for high-duty environments. It offers superior audio, long battery life, and advanced encryption (ARC4/AES).
- GPS & Safety: Unlike the standard PD785, the “G” variant includes a built-in GPS module for location tracking and emergency messaging. It also supports “Man Down” and “Lone Worker” safety features.
- Dual Mode Connectivity: Operates in both analogue FM and digital DMR (Tier II & III) modes, allowing for a smooth transition from legacy systems.
- Rugged Design: Built to withstand harsh environments with an IP67 rating (dust-tight and submersible in 1m of water for 30 minutes) and MIL-STD-810 C/D/E/F/G compliance for shock and vibration resistance.
- Channel Capacity: Supports up to 1024 channels across 64 zones.
- Audio Quality: Uses narrowband codec and digital error-correction technologies to provide clear audio in noisy environments.
- Frequency Bands: Available in specific single-band versions for VHF (136–174 MHz) or UHF (typically 400–470 MHz
