+### The US902-928 band

+To get started with a T-Beam device working on the **US902-928** band, you need to:
+* Tune the tracker frequency to the desired value from that band:
+  ```
+  "lora":
+  {
+		"frequency_rx": 913880000,
+		"frequency_tx": 913880000,
+		...
+  }

+The above example uses LoRa channel #6 (913.88MHz), but *use it at your own risk* and make sure to respect local regulations!
