USDX-BATT HF QRP SDR Transceiver Full Set 8 Band All Mode Built-in Battery 3 Buttons w/ Microphone

USDX-BATT HF QRP SDR Transceiver Full Set 8 Band All Mode Built-in Battery 3 Buttons w/ Microphone

Description:
uSDX_BATT is optimized and modified based on the open source project uSDX/QCX-SSB of Guido PE1NNZ. uSDX is a shortwave QRP SSB/CW transceiver. With built-in battery, microphone, 1602 display, and ultra-small size, it is easy to carry and convenient to use.
