TYT MD-390 Review (2025): Rugged Waterproof DMR Radio

1 Quick Facts About the TYT MD-390

2 Pros and Cons at a Glance

3 2025 Update & Buyer Caution

Firmware Status: The last official TYT firmware release for the MD-390 dates back to 2021. Since then, no new updates have appeared, and community builds vary by hardware revision. Users report “bricked” radios after mismatched updates—so always back up your firmware and codeplug before flashing anything new.

Feature Relevance: Newer DMR handhelds (such as the Radioddity GD-77 or Anytone D878 series) offer dual-band coverage, Bluetooth, GPS, and USB-C charging. The MD-390 lacks these modern extras but still excels as a rugged single-band value radio.

4 Who It’s For

• Operators who need a waterproof, rugged DMR handheld for outdoor or emergency use.
• Users who operate primarily on UHF or VHF and value simplicity over extras.
• Anyone wanting an affordable backup or go-bag DMR radio that can take abuse.

5 Introduction

The TYT MD-390 first gained popularity in the mid-2010s as the tougher, IP67-rated twin of the beloved TYT MD-380. Designed for both commercial and amateur use, it offered a rare mix of durability and affordability. Its reinforced housing, sealed ports, and loud speaker made it a field-ready radio when others were still office-bound. Compatibility with MD-380 codeplugs simplified programming and transition for existing DMR users.

Nearly a decade later, the MD-390 still holds its own as a value-focused, field-proven handheld for operators who want a radio that just works.

6 Design & Build Quality

The MD-390 feels purpose-built for outdoors. Its reinforced case, raised knobs, and grippy texture make it easy to operate with gloves. A screw-in metal cover replaces the MD-380’s loose rubber flap, ensuring the IP67 seal stays intact. The plastic PTT button feels less tactile than the older rubber style but is more durable long-term.

7 Performance (Audio, RF & Interface)

Audio Quality: The speaker delivers loud, clear audio with excellent low-frequency response. Transmit reports are natural and well balanced on DMR and analog FM.

RF Performance: With 5 W output and both stubby (12 cm) and extended (36 cm) antennas included, the MD-390 performs strongly on repeaters and hotspots. The longer antenna improves range but adds bulk.

Display & Interface: The colour LCD is bright and readable, showing channel, zone, frequency, and talkgroup info. Menus are dated but functional; button response lags slightly versus modern DMR radios.

8 Programming & Compatibility

• Front-Panel Programming: Edit frequencies, colour codes, and talkgroups from the keypad — ideal for field changes.
• TYT CPS Software (Windows): Enables advanced zone and contact management. Fully compatible with MD-380 codeplugs for easy migration.

Firmware Note (2025): Before any update, verify your board revision and back up firmware and codeplug files. Incorrect flashes can render the radio unusable.

9 Battery, Accessories & Package Contents

The 7.4 V / 2,200 mAh Li-ion battery provides roughly 12 hours of mixed DMR/analog use. Charging via the desktop cradle takes 3–4 hours, and the green LED stays on even after removal — a minor quirk. Accessories (speaker mics, batteries, chargers) remain widely available in 2025.

• TYT MD-390 radio (UHF or VHF)
• Stubby & extended whip antennas
• 7.4 V / 2,200 mAh Li-ion battery
• Desktop charger cradle + AC adapter (120/240 V)
• USB programming cable
• Earphone with PTT and belt clip
• User manual

10 Alternatives to Consider

• TYT MD-380: The MD-390’s non-waterproof sibling with strong community firmware support.
• Radioddity GD-77: Dual-band DMR handheld with open-source firmware and USB-C charging.
• Anytone D878UV II Plus: Premium dual-band option with Bluetooth, GPS, and modern UI.

11 Final Verdict

The TYT MD-390 remains a field-proven, rugged, waterproof DMR handheld that continues to earn respect in 2025. Its aging firmware and limited features are outweighed by excellent build quality, strong audio, and reliability. For operators who prioritize durability over cutting-edge features, the MD-390 is still an easy recommendation — especially as a dependable secondary or outdoor radio.
