Open Source Android Radio

One Device. Infinite Possibilities.

The CJ-1UV runs Android 14 on top of a real dual-band DMR transceiver — DMR Tier 1 and 2 plus FM Analog across 136–174 MHz and 400–480 MHz, with built-in AES256 encryption when you want a conversation to stay private.

Open source means you can customize, collaborate, and stay ahead. Build your own apps, modify existing features, and contribute to a global community of operators — instead of waiting on a vendor to unlock the next feature.
