New Community-Requested DMR Features

The V3 adds two highly anticipated features requested by the ham radio community:

1. Talker Alias support
   During DMR digital contacts, the radio displays the caller’s assigned alias instead of only a numeric ID. This makes both local repeater communications and cross-region network calls much more intuitive and user-friendly.
2. Preloaded 30,000-entry contact database
   The radio comes factory-preloaded with a contact database covering mainstream DMR user IDs. New owners can get on the air with common contacts right out of the box, eliminating the hassle of manual bulk contact imports and drastically shortening initial setup time.

Important Compatibility Note

V2-generation HD2 radios cannot be upgraded to V3 firmware via software flash, and they are not compatible with the RETEVIS CPS programming software. This is due to the fundamentally different software architectures between the two generations.

Why Choose the HD2 V3

Moving forward, the HD2 product line is centered on the V3 iteration. By unifying the CPS software ecosystem, adopting a universal codeplug format, adding practical community-requested features, and upgrading the display, this DMR handheld delivers a noticeably smoother day-to-day user experience.

We will continue to roll out regular firmware updates with new features and performance improvements for the V3 platform going forward.

For anyone looking to pick up an HD2, the V3 version is the clear choice for simpler, more streamlined setup and operation, and the most complete, up-to-date feature set available.
