# SUB-GHz

> Receive, analyze, save, and replay signals through a CC1101 module.

The `SUB-GHz` menu appears only when the device detects a **CC1101** module. Use it only with devices and frequencies you own or are authorized to test, and check local radio regulations before transmitting.

>
> Unauthorized interference, interception, or replay may be illegal. Use these tools only in a controlled test environment.
