Hytera MD785 UHF DMR Vehicle-Mounted Mobile Radio (400–470 MHz)
The MD785 UHF is a vehicle-mounted mobile DMR radio operating on 400–470 MHz - 45W high power, IP54, MIL-STD-810 C/D/E/F certified. Designed for dashboard or console installation, the MD785 UHF runs DMR Tier II/III and analog FM in dual mode with 1024-channel capacity, a built-in 5W speaker, and ARC4 encryption as standard. UHF penetrates buildings and structures effectively, making it the standard choice for fleets operating across mixed indoor and outdoor environments. The MD785G UHF adds integrated GPS for real-time vehicle and fleet tracking.
Why Professionals Choose the Hytera MD785 UHF
The MD785 UHF is a vehicle-mounted mobile radio - 60×174×200 mm, 1.7 kg - built for dashboard or console installation in fleet vehicles operating across urban and mixed indoor/outdoor environments. At 45W high power on 400–470 MHz, it covers the frequency range used by manufacturing facilities, warehouses, healthcare campuses, urban security fleets, and airport ground support vehicles where UHF's building-penetration advantage over VHF is operationally relevant.
The radio connects to the vehicle's 13.6V DC supply and supports the full DMR Tier II/III feature set. TDMA dual-slot operation doubles channel capacity on the same spectrum allocation. XPT pseudo-trunking dynamically assigns free slots without a dedicated control channel, keeping infrastructure lean for mid-size fleet deployments. DMR Tier III trunking unlocks via software licence — no hardware replacement. Dual-mode operation handles both digital and analog UHF channels per-channel, supporting mixed fleets during phased migration. Seven programmable keys and the keypad microphone allow in-cab operation without taking hands off the task.
IP54 covers dust protection and water splash resistance from any direction. MIL-STD-810 C/D/E/F addresses temperature from –30°C to +60°C, vibration, shock, humidity, salt fog, and sand — the standard compliance set for vehicle-mounted mobile equipment. The 2.0-inch TFT color display (220×176 px, 262,000 colors) provides readable status output from the driver's position.
The MD785G UHF adds integrated GPS with cold-start TTFF under 1 minute, warm-start under 10 seconds, and under 10 meters horizontal accuracy. Position data and GPS text messages display on-screen and integrate with Hytera dispatch software for real-time fleet visibility. FCC Part 90 licensed.

FCC Licensing and Compliance Support
The Hytera MD785 and MD785G UHF operate on licensed Land Mobile Radio frequencies under FCC Part 90. A valid FCC Business Radio License is required for each UHF frequency used in commercial vehicle or facility operations in the United States.
UHF frequencies in the 400–470 MHz range are widely allocated for industrial, commercial, healthcare, and urban fleet operations. Frequency coordination with existing licensees in your area is required as part of the licensing process.
As an authorized Hytera dealer, AXDIGITAL supports customers with frequency coordination guidance, licensing requirements, and fleet programming. Contact our team to confirm frequency availability and bulk pricing for your vehicle fleet.
FAQ
What is the difference between the MD785 UHF and MD785G UHF?
Both models share the same UHF platform, 400–470 MHz range, 45W output, IP54 rating, and accessory ecosystem. The MD785G UHF adds an integrated GPS module — TTFF under 1 minute from cold start, accuracy under 10 meters — with on-screen position display and GPS text messaging. It integrates with Hytera dispatch software for real-time vehicle fleet tracking. Specify MD785G if vehicle location visibility is required.
Why choose UHF over VHF for a vehicle-mounted mobile radio?
UHF (400–470 MHz) penetrates buildings, warehouses, and concrete structures more effectively than VHF, making it the right choice for fleets that move between indoor loading docks, parking structures, facilities, and outdoor yards. If your vehicles operate exclusively in open outdoor terrain — port grounds, construction sites, rural areas — the MD785 VHF may deliver better long-range coverage on the same repeater. For mixed environments, UHF is typically the safer default.
Can the MD785 UHF operate as a desktop base station?
Yes. With the optional PS22002 300W mobile power supply, the MD785 UHF runs from AC mains power as a desktop or fixed base station. This is a common configuration for dispatch offices, site command posts, and reception desks where a vehicle-grade radio provides higher output power than a typical desktop unit. An appropriate UHF external antenna is also required for fixed installations.
