1. I C A R U S (Internet Controlled Amateur Radio UHF/HF System) Abstract The problem with High Frequency (HF) radio setups is that they require a large amount of money and space for an individual to buy and maintain. The proposed solution to this problem is to have an HF radio system that amateur radio operators could access through a handheld radio and control through an internet connection. This would eliminate space and cost restrictions while allowing worldwide communications. • Technical Approach • The design for ICARUS will consist of 7 major components: • HF / VHF radio: Enables world wide communications. • UHF repeater: Extends local range for handheld radios. • Antennas: Allows transmissions of radio signals. • Antenna control board: Correctly positions the antenna. • Audio control board: Routes audio to the proper radio. • I/O board: Interfaces control boards and the computer. • Computer: Controls equipment and runs the web server. • End Product • The final deliverable system will: • Provide worldwide communication through a UHF handheld radio. • Incorporate a computer controlled HF/VHF radio and an antenna system. • Allow remote control of system functions through a web browser. • Limit access to the system to authorized users. • Allow users to conveniently operate a HF radio system. • Allow hardware costs to be divided among many users. UHF 442.375 MHz HF / VHF 3.5 – 148 MHz Control via Internet Connection User with UHF Handheld Radio and Computer I C A R U S Distant HF Amateur Radio Operator ICARUS allows world wide communications from a handheld radio • Assumptions & Limitations • User must have access to computers with internet connection. • User must be a licensed amateur radio operator familiar with the use of a UHF repeater system. • User has limited control of HF radio and repeater functions. • Milestones • October 2000 – Raising antennas, running coax. • November 2000 – Setting up web server. • December 2000 - Construction of the rotor control board, audio control board, I/O board, software and interfacing HF radio. • March 2001- Initial trial tests of system. • May 2001 – Final testing of system.
