In this review the Retevis RT3S DMR Radio is evaluated for hikers, travelers and amateur radio users who need an affordable dual band handheld with long runtime and location features.

The reviewer found it to be a capable entry-level DMR radio with strong value for money and useful programmable features.

Who It's For

The RT3S is best for ham operators, outdoor teams and travelers who want a versatile handheld that supports DMR and analog workflows and includes GPS APRS for location sharing. Its high channel and contact capacity suit users who manage many frequencies or groups, and the OpenGD77 support appeals to those who like to customize firmware.
