Doug Smith, KF6DX, will speak on the latest in digital-voice and
software-radio technology in Amateur Radio. Doug was one half of the world's
first transatlantic digital voice contact on the HF ham bands in November of
last year. He will describe some of the history of digital voice modes,
advantages and disadvantages, and what digital voice and multimedia
communications bode for the future of ham radio. A live demonstration will
be included.

Doug will also discuss burgeoning developments on the software-radio front,
including current projects to put affordable software radios into the hands
of Amateur Radio operators and experimenters. He will go lightly into some
technical details of state-of-the-art hardware designs and DSP algorithms,
including those of the new Ten-Tec Orion and various digital
direction-conversion transceivers.

Doug Smith has 25 years experience designing communications equipment for
commercial, military and Amateur Radio markets. His work has included
control systems, DSP, frequency synthesis and speech compression. Doug
chairs the ARRL Digital Voice and Software Radio Working Groups, but is
perhaps best known as Editor of QEX: Forum for Communications Experimenters,
the bimonthly technical magazine of the ARRL. He is the author of dozens of
articles, the DSP chapter in recent editions of The ARRL Handbook, and of
Digital Signal Processing Technology: Essentials of the Communications
Revolution, published late in 2001. Doug was educated at the California
Institute of Technology, Pasadena, CA. He received the 1998 Doug DeMaw
Technical Excellence Award for his writing.
