The Barrett 4050 HF Software-Defined Radio (SDR) transceiver incorporates a new generation of technology. It provides secure digital voice, email, data transfer, and has an intuitive touchscreen operator interface. The radio can also be controlled from a number of different remote platforms. The 4050 handset app can be installed on smartphones, tablets, laptops or PC's running iOS, Android or Windows, and provides full remote control of the radio. A smartphone with the app installed can therefore be used as the radio handset. This could either be used locally using Wi-Fi or from a remote location, providing IP connectivity.
