ComJoT Radios | CJ-1UV & CJ-26 — Open Source Android Amateur Radios

Why ComJoT

Most "Android radios" run last decade's software

A radio with an outdated, locked-down operating system can't keep up with the apps, security patches, and tools you actually use. ComJoT radios run modern Android with open source software — so you can install what you want, build your own features, and trust exactly what's running on your device.

It's a familiar Android experience on top of a serious dual-band DMR transceiver. Click and talk on DMR, run APRS and digital modes, or drop into any app — all from one hand.
