Welcome to Winrad.org

by Jeffrey Pawlan, WA6KBL

Winrad is a free amateur radio program conceived by Jeffrey Pawlan, WA6KBL, that implements many Software Defined Radio (SDR) functions which are needed for weaksignal reception including EME, troposcatter, cloudscatter, and very long distance microwave terrestrial contacts. It also works well for general HF reception.

Winrad will accept input from any Windows soundcard, from Virtual Audio Cable, or direct digital input from several SDR receivers which have appropriate drivers written for Winrad in the form of a DLL plus support files. These files must be installed in the Winrad progam directory in order to run. You must do all installation and run Winrad with Administrator privileges.

Alberto, I2PHD wrote the code from its beginning until retiring from it in Oct, 2008. Now the software team of volunteers is lead by Charles Buse, HB9EGW. If you are interested in helping, note that you will need to use the Borland/Codegear/Embarcadero IDE. Please contact Jeffrey Pawlan, WA6KBL.

If you start from the original source code and make a new program that is not part of this project, please do not call it Winrad as this name is my own creation and the program Winrad will remain on this website which I own.

Jeffrey & Alberto

All recent versions of Winrad run under Windows 2000, XP, or Vista. An earlier version v1.23 is also provided because it will still run under Windows 98SE.

New changes and fixed in the new version 1.4.2 build 49

The LO is now correctly frozen while recording or playing back a wav file.

<>

New changes and fixed in the new version 1.4.2 build 48

fixed the problem of the mouse wheel and arrow keys staying focused after selecting the number of averages you want.

New changes and fixed in the build 47

Pressing the "C" key did not center tune frequency. Now fixed

TuneChanged not called consistently. This affected PE0FKO's dll for the softrock. Now fixed

Saved AGC settings not restored. Now fixed

Mouse wheel only works when over blue window. Now fixed so mouse wheel works anywhere on the entire screen

AGC default when first installed was off. People not realizing this would find that there was little or no output with the Threshold control all the way down (since iit behaves like the RF Gain control on a regular radio). Making the threshold too high causes overload. Now we make the AGC default setting = "On"

If you set the frequency to very high frequencies like microwave or mm-wave frequencies and then come down in frequency the frequency scale was displaying negative numbers. Now this is fixed

I have tested Winrad with a Perseus on Win2K, XP, and Vista on many different computers. It always works perfectly here. If you are seeing an error message with your installation, then please help us test because I cannot reporoduce your problem.

In the Next Version....

Add internal interface to a virtual COM serial port server so that external transceivers can be synchronized in frequency to the receiver in Winrad. This will be done with OmniRig and perhaps RigSync

DSP

Improve the AGC to make it user customizeable as done in some transceivers.
