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.

All recent versions of Winrad run under Windows 2000, XP, Vista and 1.5.0 has been tested on Windows 7 (32 bit) with a Perseus. An earlier version v1.23 is also provided because it will still run under Windows 98SE.
There is a yahoo discussion group for Winrad. If you are interested in joining, send me an email with your name, either your callsign or reason for joining, your location, and your email address.
New buttons added so you can change the mousewheel tuning steps (10Hz or 100Hz)
New additional extended adjustment range for the I & Q amplitude and phase balance controls. This is needed for some Softrocks, especially the 2m converter.
Added internal interface to a virtual COM serial port server so that external transceivers can be synchronized in frequency to the receiver in Winrad. This is done with OmniRig. You need to have OmniRig and your transceiver interface files loaded and tested before starting Winrad. Winrad then starts OmniRig running if you select it in the options in Winrad. It works bidirectionally with the Perseus. If you tune the Perseus, then your transceiver will immediately follow. If you tune your transceiver then the Perseus will follow. This has been updated so that ICOM transceivers will work correctly. Also two transceivers may be connected if you have OmniRig set up correctly for two transceiver control. There is now a selector in the Winrad omnirig support menu that allows you to select radio 1 or radio 2.
The DLL to external receivers has been fixed so that TunedChanged works correctly. This has been tested with the Softrock, the Perseus, the SDR-IQ, and the latest version of the PMSDR. All tuning and frequency display now works well.
An option was added for adding an offset frequency. Winrad can now display up to mm-wave frequencies so if you have a transverter or a downconverter connected to the receiver connected to Winrad, then enter and enable the appropriate offset frequency.
An option was added to use Winrad with Undersampling receivers. Thee are three I know of and perhaps more that I do not know. The SDR-14, the modified QS1R, and the modified Perseus. You will see an optional menu in which you enter the Nyquist frequency and the tuning range, and an enable box. If the Nyquist frequency is 0 then it is actually in standard sampling mode. If your sampling rate is 80MHz such as in the Perseus, then put 40 in the Nyquist box to use this. I then use the modified Perseus for 144MHz reception so the selected range should be set to 120-160MHz.
