Malahit Tech USDX TR 5‑Band Transceiver Compact

Description

Product Overview

The USDX TR 5‑Band transceiver from Malahit Tech is engineered for serious amateur radio operators who need a lightweight, high‑performance rig. Housed in a rugged 3D‑printed army‑green case, the unit measures just 2 × 4 × 2 inches and weighs 8.11 oz, making it ideal for backpacking, field days, or emergency response. It supports the classic LO bands of 80, 60, 40, 30, and 20 m, driven by a 1.2‑version mainboard and a 1.0‑version RF board. The device ships with a completed bootloader and firmware pre‑installed, and includes a serial number label inside the packaging for easy tracking.

Usage

Designed for portable and field operations, the USDX TR excels in remote camps, disaster‑relief sites, and on‑the‑go contesting. Its compact form factor fits comfortably in a small gear bag, while the 3.5 mm × 1.35 mm power jack accepts a wide range of battery solutions. Users can program a personal call sign after consulting the included instructions, allowing seamless integration with existing station setups.

Why Choose Us

Malahit Tech combines precision engineering with user‑centric design. Every unit undergoes rigorous quality checks, ensuring the bootloader is correctly programmed and the firmware version matches the buyer’s preference—official (no spectrum display) or beta (spectrum display with a slightly reduced menu). The absence of a serial number on the OLED screen eliminates accidental exposure, while the serial label in the bag guarantees traceability. Our 3D‑printed case provides superior impact resistance compared with standard plastic housings.
