 ==== Getting SDR# Running in Linux ====
-As of 14 September 2015 SDR# works again in Linux on x86/x64 and ARM using Mono!  This has been tested on Linux Mint 17.2 and an Odroid XU4.
+As of 14 September 2015 SDR# (along with AstroSpy and SpectrumSpy) and works again in Linux on x86/x64 and ARM using Mono!  This has been tested on Linux Mint 18 x64 and an Odroid XU4.
-The fact that SDR# worked in Mono at all was a happy accident.  The author did not intend this and is not obligated to keep the code backwards-compatible with Mono.
+The fact that SDR# worked in Mono at all was a happy accident.  The author did not intend this and is not obligated to keep the code backwards-compatible with Mono.  Any performance issues with SDR# in Mono are a problem with Mono **NOT** SDR# - //do not complain about SDR# on Linux until Mono gets much better at executing .net code//.
-There are 2 ways to do this, you can use the PlayOnLinux way shown in [[http://f4bpp.raidghost.com/articles.php?lng=fr&pg=75&tconfig=0|in French here]] or and [[http://f4bpp.raidghost.com/articles.php?lng=en&pg=75&tconfig=0|English here]] or the Mono way detailed below.

+== Instructions (updated 16 Jul 2016) ==
-  * Install ''mono'' 4.0.4 (or later) for your distro from [[http://www.mono-project.com/download/#download-lin|here]].  This is the Linux version of Microsoft's .net.
+  * Install ''mono'' 4.4 (or later) for your distro from [[http://www.mono-project.com/download/#download-lin|here]].  This is the Linux version of Microsoft's .net.
   * Install ''libportaudio2'' to make sure sound works.  <code>sudo apt-get install libportaudio2</code>
   * RTLSDR users:  I used the cmake version as detailed [[http://sdr.osmocom.org/trac/wiki/rtl-sdr#Buildingthesoftware|here]].  Don't forget to run ''ldconfig'' as root at the end to sort the newly installed libraries out.
-  * Airspy users: Download and install the host drivers from [[https://github.com/airspy/host/|here]].

-  * Download the latest zipfile copy of SDR# from [[http://airspy.com/download|here]] - you will need to make an account first.
+  * Download the latest zipfile copy of SDR# from [[http://airspy.com/download|here]].
   * Unzip to a new directory.
   * ''cd'' into the new SDR# directory and type the following: <code>ln -s /usr/local/lib/librtlsdr.so librtlsdr.dll

   * If the last command doesn't work type ''locate libportaudio.so.2'' and try again with the new path.  On 32 bit systems it will be in a different directory to what's shown here.
   * With your favourite text editor open ''FrontEnds.xml'' and find the line <code>   <!-- <add key="RTL-SDR (USB)" value="SDRSharp.RTLSDR.RtlSdrIO,SDRSharp.RTLSDR" /> --></code> and remove .net comments of so that it looks like: <code><add key="RTL-SDR (USB)" value="SDRSharp.RTLSDR.RtlSdrIO,SDRSharp.RTLSDR" /></code>  This will enable use of the RTLSDR dongle. Comment out any radios you don't have so you don't get any startup errors and exceptions for non-existent radios.
-  * Before running SDRSharp you can compile it so that it may run a bit faster.  To compile do: <code>mono --aot --optimize=all SDRSharp.exe</code>

-  * If you get audio stutter (I do on my i7 CPU!) change the audio latency from 100ms to 200ms or more.  It seems Mono doesn't run SDR# anywhere as efficiently as the native Windows CLR.  I have tried --optimize=all and also the --llvm options and it doesn't seem to help.  Any advice appreciated!

+  * If you still get audio stutter on the Airspy at 10MS/s then try 2.5MS/s.  This won't change until Mono improves (drastically).
