Codan XTEND allows you to operate a Codan HF SDR radio via your smartphone or tablet. This provides you with additional mobility, and an easy-to-use interface. It allows you to perform the following for pre-defined contacts that are programmed into your radio: - Make and receive Selective and Emergency HF voice calls - Send and receive HF messages (including in-link messages) - Send your position to another radio, or request the position of another radio, and view these positions in Google Maps
