This modification was created to support ExtIO based SDR hardware on lower HF.
Which was (and maybe still is) not possible using the original SDRSharp app.

Get SDRSharper_02g.zip and unpack/unzip files into a single destination folder.

See also Help.txt file included in the Zip-file or click [?] button on bottom right of SDR.

SDRSharper Requires Microsoft .Net framework 3.5

On most modern W7 and above systems already available.

SDRSharper supports most ExtIO enabled SDR hardware front ends.
See lowerr list on http://www.hdsdr.de/hardware.html
Place appropriate ExtIO*.dll file in your SDRSharper folder.

Package already contains ExtIO dll's for Perseus and PapRadio SDR.
Furthermore the RTLSDR DVBT Dongle is supported.
