The ET-C58D is a dual-mode handheld radio compatible with both DMR digital and 4G LTE public networks. It's positioned for niche scenarios where public network coverage is insufficient and analog signals are inadequate: mountain patrols, large construction sites, metal-enclosed factories, and emergency backup links. Its core selling point is its "three-mode integration"—independent DMR, independent public network, and analog-to-public network repeater—allowing for protocol layer conversion within a single device without the need for an additional gateway. Today, I'll introduce it in detail.
First, let's examine the radio's appearance.
The ET-C58D offers a comfortable grip and can be held with one hand. The large PTT button has a good tactile feel.
From the side, the ET-C58D has four buttons. The main button is the public network PTT button, the one above it is the analog PTT button, and the others are programmable function buttons.
The ET-C58D features a full numeric keypad and supports manual frequency setting. This allows for easy duplication of existing channels and parameter adjustments when temporarily adding analog channels. It can also be used to send SMS messages.
On the right side are the microphone and headphone jacks, supporting dedicated 13-pin waterproof headsets and microphone sockets with excellent sealing.
At the bottom of the back is a Type-C USB charging port, allowing for convenient charging via power banks, laptops, and car chargers.
The ET-C58D boasts high IP68 dust and water resistance. Our tests showed that even after prolonged immersion in water, it remained perfectly usable for walkie-talkies.
The ET-C58D also supports repeater mode: it can relay analog-to-public network signals, enabling communication between different devices, essentially functioning as a public network gateway.
The ET-C58D, with its battery, weighs only 356.4g, similar to the Motorola DP4801e, which is not too heavy.
In summary, the ET-C58D is a brand-new professional dual-mode radio. It offers 4G nationwide calling capabilities similar to a public network walkie-talkie, but unlike ordinary public network walkie-talkies, it doesn't become unusable in complex environments. It allows for seamless switching between DMR and public network modes, making it suitable for outdoor use in mountainous areas, construction sites, and metal factories. Furthermore, it supports three operating modes: standalone DMR mode, public network mode, and repeater mode. No matter the environment, you can find the most suitable communication method for you.
