Winrad is a software program designed to implement a so-called Software Defined Radio (SDR), meant to run under Windows XP, Windows 2000, or Windows 98SE (only up to V1.23). In a nutshell, it accepts a chunk of up to 192 kHz coming from a half-complex mixer in form of two signals, I and Q, fed to the PC sound card. It does a fine tuning inside that segment with a point-and-click technique, demodulates (LSB/USB/CW) what has been tuned and optionally applies a series of filters to the results of the demodulation.

           The full Winrad source is now available

The full source of Winrad is now available at the link below, both the first and the second part, with the component library and the instructions on how to compile. These instructions are in the file Winrad-How-To.pdf which is in the ZIP of the second part.  I hope to not have made too many errors writing those instructions, I would have needed a clean PC on which to test the procedure, but I don't have it. Please signal any errors you may find, thanks.
