I have slightly revised the specs on how to write a DLL that interfaces with Winrad. Mainly I have added a few return codes from the "callback" API, in order to start and to stop programmatically Winrad from inside the DLL, and also to activate or deactivate the "Mute" function still from inside the DLL.
This latter function was needed to support the digital upconversion SSB exciter that Giuliano I0CG and myself have recently presented at the Modena SDR meeting. A writeup on this exciter will be published, as soon as I will have finished to translate the material into English. Also some minor errors in the document were corrected. You can get the latest version from : http://www.weaksignals.com/xeq/Winrad_Extio.pdf 73 Alberto I2PHD .
