In this latest SDRuno Video Guide,  Mike demonstrates the TM-2 Controller.

The Tmate2 is a dedicated SDR controller that simply connects to your USB 2 port and enables you to control your SDR radio. The unit is fully programmable and comes with software. Even if your PC screen is switched to another program, the Tmate2 will allow you to operate your radio.
