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. We do not have any programmers at this time. If you are interested in helping, note that you will need to use the Borland/Codegear/Embarcadero IDE version 2007. Please contact Jeffrey Pawlan.
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 1.6.1 has been tested on Windows 7 (32 and also 64 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, go to the New Winrad Group on Yahoo: click here to go to New Winrad Group You can join from there.
OmniRig working very well now
The last radio used is saved so when you start Winrad again your radio will be automatically selected.
The last state of the I/Q mode is stored so if you use I/Q swapped, Winrad will remember that and come up with this selected.
The issue of the Internationalization: use of "." or "," decimal fraction separators depending on country has been fixed.
New: you may adjust the parameters of the AGC buttons by right-clicking on them. A pop-up window will appear and you can change the values. Slow and Fast AGC are separate except for one common parameter. Note that you can "break" Winrad by moving the values too far. You must have the Threshold slider up most of the way or perhaps all of the way to really hear the effects of the AGC.

Juan Jose de Oņate, M0WWA has made a new version of his high performance tuneable preselector and he has written control software for it to work with Winrad. His dll allows Winrad to control your SDR and this preselector at the same time. Please look at the following webpage: http://herostechnology.co.uk/pages/SCR_Preselector.html where you will find a complete description and ordering information. If you already own one of these, you may obtain the Winrad interface guide here: http://www.m0wwa.co.uk/page/scr_preselector_Winrad.html
Juan writes that he has tested this with the Softrock and the Lazydog receivers. He expects that it should work with all Winrad capable receivers if they have implemented the extio dll correctly. Please contact Juan directly for questions and support.
