SDR Presentation Announced for Chicago ARRL/TAPR DCC(Digitial Communications Conference) Sunday Seminar
'Software Radio Through the Looking-Glass' Phil Harman, VK6APH One of the most exciting, and rapidly evolving, aspects of Ham Radio is that of Software Defined Radios. What was initially left to technical minded experimenters is now starting to move into the main stream. The latest SDRs offer performance equal to the best analogue radios on the market. For those brought up on analogue radios there is quite a learning curve to understand exactly how these new radios work, what they do well and what shortcomings there have. Phil will guide us through the basics of SDRs right up to the very latest techniques that digitise signals directly at the antenna socket. Using diagrams and a minimum of math he will cover such subjects as front end design, mixers, why we need I and Q signals, digital up and down conversion,AGC techniques, noise blanking and high efficiency Power Amplifiers. The presentation will be highly interactive, so be sure to bring along that question that has been puzzling you for so long! Biography: Phil Harman, VK6APH, has held a ham license for over 40 year. For much of this time he has worked on leading edge RF techniques related to receivers and transmitters. Phil's current passion is the development of fully digital HF radios. Phil co-writes the Software Defined Radio column in the RSGB Radio Communications journal and also co-authored the SDR chapter in the latest RSGB Handbook.
