Simon was gracious enough to provide directions to build a DLL to directly support the RTL Dongle in his new SDR-Radio.com V2 application. In an effort to help others out I have followed his directions and built the DLL to make it available to those who do not have the required development tools. I used Microsoft Visual Studio 2010 and the following source code:
http://cgit.osmocom.org/cgit/rtl-sdr/
http://v2.sdr-radio.com/Portals/0/Download/SourceRTL2832u.zip
http://sdr.osmocom.org/trac/attachment/wiki/rtl-sdr/RelWithDebInfo.zip
I followed the directions at: http://v2.sdr-radio.com/Configuration/RTLSDRs/BuildingDlls.aspx
In the zip file you will see two directories:
If you are using a 64bit copy of windows you will need to copy the files in the 64bit directory to the following location:
C:\Program Files\SDR-RADIO-PRO.com
For 32bit windows copy them here
C:\Program Files (x86)\SDR-RADIO-PRO.com
Here is a link to the DLLs.
