To the best that I can see using HDSDR, the software doesn't provide any items for transmit capability - or any of the features that would be required for setting up various levels for transmitting. It would seem that even the the ExtIO would have that ability to switch the SDR radio, if the software itself doesn't have any features to support that ability, then it is useless. It would be something that the HDSDR author would have to implement before the DLL would be of any use to anyone.
Just my opinion.

I think at one point their business model might have depended on radio manufacturers paying for this key to enable HDSDR to transmit using their radios.

A: The HDSDR software doesn't communicate with the SDR hardware directly. It communicates with the SDR radio hardware through an External Input Output Dynamic Link Library (ExtIO-DLL) file, which is a type of plug-in. Alberto di Bene designed the DLL interface so that Winrad can operate with a wide range of SDR hardware. We extended the DLL-interface to support TX switching. Winrad and HDSDR can support new hardware radios using an ExtIO-DLL file without the need to change the HDSDR software. ExtIO DLL files are written by anyone who wishes to provide support for any particular SDR hardware. In this manner, several radios can be used with a single piece of software. The software in this case is HDSDR. Q: How do I develop an ExtIO-DLL? A: At this point, we assume that you are a software developer familiar with C/C++ programming. Here is a "hopefully" well documented <http://www.hdsdr.de/download/LC_ExtIO_Types.h>header file (updated February 24, 2014), which specifies the interface between HDSDR and an ExtIO-DLL. Here is also an example <http://hdsdr.de/download/ExtIO/ExtIO_Demo_101.zip>ExtIO DLL with sources as public-domain, developed with Microsoft Visual C++ 2008 Express Edition. Balint wrote one for USPR http://wiki.spench.net/wiki/ExtIO_USRP dunno if it transmits. So if anyone is willing to make this DLL it would be huge benefit as we could finaly transmitt on windows with HDSDR _______________________________________________ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev _______________________________________________ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
