A compact Android 8.1 PoC radio with a 2.4-inch touch screen, a number keypad, IP65 sealing and a removable 3,500 mAh battery. It is listed for TASSTA, WalkieFleet, Privox and Inrico's own iConvNet platform.
The T320 supports 7 LTE FDD and 4 LTE TDD bands on Inrico's list for the EU version, including the 800 MHz band 20 that most EU networks use outside cities.
These services list the T320 as supported. Zello does not list the T320, but Inrico names it with Zello in a 2021 case study, and the app runs on Android 7 or later. Pick one and try what it can do.
The radio's keys work too: PTT plays the next call (hold it to talk), the knob or ▲▼ change the group, ◀▶ switch the app’s screens, the red key stops.
