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

- Loudspeaker with built-in LM386 amplifier driver
- Use original LM4562 or LM833 op amp chip
- Three buttons: PTT/MENU/MODE, built-in MIC
- Front MIC/PTT interface (UV-3R hand microphone)
- Abundant interfaces: HP, PTT OUT (CAT), K-head hand microphone, MIC/PTT hand microphone
- BNC antenna interface (BCN-SL16 adapter required, easy to match the antenna)
