Compact Body, Professional Performance
The ETMY ET-D330 is a digital two-way radio that packs full Tier-II DMR performance into a palm-sized body, weighing only 285 grams and measuring just 125 mm in diameter. It delivers 10 watts of RF output power in VHF, UHF bands, providing city-wide communications for security teams, construction workers, and outdoor clubs without incurring hefty phone bills.

Out of the Box, True DMR Digital
No need to plug and unplug encoders or purchase expansion boards—every ET-D330 comes pre-installed with digital mode, featuring 12.5 kHz DMR channel spacing, Color Code 1 encoding, and the same 16-channel selector as most common analog solutions. This plug-and-play functionality makes it the ideal DMR handheld radio for beginners, allowing them to immediately experience clear digital communication while leaving room for future expansion.

Rugged and durable, superior quality.

Supports IP68 high protection rating. This DMR handheld radio is completely sealed and dustproof, capable of continuous submersion in 2 meters of water for 30 minutes, even in torrential rain, offshore drilling platforms, or dusty industrial environments. However, its price is far lower than that of similar products from mainstream brands.

One-touch emergency call button

Press and hold the dedicated orange button for three seconds, and the radio will send an alarm signal with a GPS marker to all members on the channel, followed by a real-time voice call.

Built-in 10-minute recording function

The built-in 10-minute rolling buffer records every call, safety instruction, or shift handover log. Files are timestamped and can be played back through the radio's built-in speaker.
