Hytera Communications, a Shenzhen maker of professional radio equipment, has added a compact repeater to its digital mobile radio, or DMR, line. The HR65X is the company's second repeater after it began renewing its H Series in 2021, and Hytera says it is small enough to mount on a wall or carry in a backpack, weighing about two kilograms, and is meant to let a business extend the reach of a two-way radio system where it is needed.

The device comes in a 25-watt version with a fan and a 10-watt version without one, and Hytera says it can run from mains power or an optional battery, which keeps it working for up to nine hours at the lower power when the electricity fails. It can serve a single site or link into a larger IP network, and with a drone it becomes an emergency coverage option. The company says a network management system lets an operator update settings and watch the equipment remotely.

New hardware, and the radios already in the field

The most useful detail is a backward-looking one. Hytera says the repeater works in analog mode, in DMR mode, or in a mixed mode that keeps older analog handsets talking to a new digital network. That matters to the buyers of this equipment — factories, hotels, event organisers, emergency services — who rarely replace a radio fleet at once, and who measure any upgrade by how much of their existing investment it protects.

Two things are left unstated. Hytera gives no price and no on-sale date, so a reader cannot judge whether compactness is worth the cost of a repeater plus a drone or a battery pack. And a coverage claim is a laboratory or site figure until it meets a real building with thick walls and competing signals. The HR65X is a sensible piece of kit for a market that prefers to keep what it has; whether it earns its place is a question for the sites that deploy it.
