One could easily conclude that, in the era of the Internet and communication
satellites, short waves are destined for obsolescence. But the reality is quite
different. On the contrary, shortwave communications seem to be
experiencing a new period of revival and vigorous growth.

This revival is partially caused by the fact that shortwave is still the only
technology able to send signals around the globe with minimum power and
without the need for expensive, and potentially failure-prone or sabotage-
prone infrastructure. In the era of increased security concerns, this is an
important reason for the continuing interest in shortwave.

The other reasons include newly found applications, for example HF email,
and emerging new types of digital modulations (such as DRM broadcasting),
offering more reliable and higher quality communications than before.

All this will ensure that shortwave will remain what it always has been; an
amazing place of action, a cacophony of sounds; a babel tower of exotic
languages and music, alive with broadcasters both official and clandestine;
a haven of spies; a playground of pirates, terrorists and freedom fighters
alike; an exciting mix of the respectable, the serious, the crazy and the
dangerous. Long before the Internet, the shortwave world was always
borderless. And quite like the Internet, impossible to tame and control.

Welcome to shortwave. And welcome to the WiNRADiO G3 SERIES
receiver. Your new receiver is a world-first in more than one respect. Most
importantly, it is the first commercially available Software Defined Receiver
(SDR), where the entire demodulator and the last intermediate frequency
stage are performed by software running on a personal computer rather
than using conventional hardware circuits, or a dedicated Digital Signal
Processor. Your PC probably has more power than even the fastest DSP
had only a few years ago. Your new WiNRADiO G3 SERIES receiver is now
ready to take advantage of that power. Enjoy!
