This is an amateur radio transceiver that operates on the medium or short wave bands. It is a software defined radio, meaning that it uses a computer to control the radio, to demodulate the signals received, and to modulate the signal transmitted. The computer control and signals in and out go through the USB connection, the antenna connects to the big silver BNC jack, the pink and green jacks are for microphone and headphones/speakers, and the black jack is for a telegraph key or iambic paddle for sending morse code.

You can make your own board from the software and schematic on GitHub or start with a kit from AE9RB.
