    FAQ


    1. Software Defined Radio Transceiver?

      Yes! This is an amateur radio transceiver that operates on all the HF amateur 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 hardware, the microphone and headphones/speakers are connected to the computer, and a morse key or iambic paddle to the hardware for sending Morse code.
