$GTCH In order to assure high clarity and accuracy in these frequencies, particularly with data communication, we intend to investigate advanced electronic systems to provide clear, reliable and secured channels. Proper architecture for the system’s implementation was chosen including the system’s logical components. One of the main challenges in such complex systems is the design and integration of an embedded software to manage the data and audio communication. The system is designed to achieve a high performance, wideband digital HF transceiver, base unit and repeater. We defined the mobile unit’s size, taking into consideration portability and mobility. The mobile unit fundamentals features were defined to ensure a user’s friendly interface (LCD touch screen) and easy operation. GBT plans to design and build a prototype with and test it within a large city limits and national ranges.
