SDR Receiver processes signals that are streamed over the network from a host computer (Mac, PC or Raspberry Pi) that is attached by USB bus to an RTL-SDR, Airspy HF+ or SDRplay radio. An rtltcp server or equivalent application running on the host computer receives baseband IQ data from the radio and streams the sampled signals over the. Please note: This App requires a FlexRadio Systems® Series-6000 Software Defined Radio (SDR) Device. However, the App also contains a FlexRadio Simulator (Demo Mode) so you can try this App even without owning a FlexRadio. PLEASE NOTE: The Demo Mode audio is by far not as good as when connecting the App to a real FlexRadio. USB stick RTL-SDR Drivers RTL2832U. Installation CD & drivers for USB TNT RTL2832U + software.

A while back I bought one of those 15 GBP DVB-T dongles to seeif they’re good for anything. Turns out, they’re pretty amazing devices, and you can’t possibly beat the price given its capabilities.
Sadly, the variety of software available for the Mac leaves much to be desired. How to get minecraft for free on mac 2020. Apart from the rtlsdr suite and Gqrx, there are very few programs available.
This evening, I turned my attention to SDRSharp - an SDR suite originally targeted at the Windows platform, written in C#. Immediately, I thought of Mono,and if it would be possible to run SDRSharp on a Mac, given a Mono runtime. Mind you - the last time I looked at Mono (around 2006), the folks behind itwere working on reimplementing Windows.Forms, so it wasn’t exactly ready for the prime time back then.
This writeup describes how to get SDRSharp up and running on Mac OS X
Download the Mono platform and install Xamarin Studio.
First, you’ll need to download the Mono runtime (an equivalent of the .NET Framework for platforms other than Windows). Head over to the project page and select Mac OSX - there are two packages to download and install:
- Mono + GTK# - the framework runtime.
- Xamarin Studio - an IDE for Mono.
Install the portaudio and rtlsdr libraries.
In order to talk to your dongle, you’ll need a library (rtl-sdr) which exposes an abstraction layer and talks to the dongle using
libusb
. Since this is a native library(compiled for a particular platform - in our case Mac OS X), you’ll need to build it from scratch using MacPorts. SDRSharp uses P/Invoke facilitiesto talk to the libraries in question. All you need to do is build them for the right architecture (i386).Assuming you have MacPorts installed, simply issue the following commands. The
+universal
variant is important.Building the latter may take a while, or at least it did in my case - ImageMagick was rebuilt among others (go figure).
Get the SDRSharp sources.
In a directory of your choice, run the following:
Sdr For The Mac Os
This will pull the latest SDRSharp sources from the repository.

Build the SDRSharp binary.
Fire up Xamarin Studio, open an existing project and select SDRSharp.sln in the sdrsharp directory you just checked out. Change the active configuration (Project | Active Configuration) to |
Release|x86 . Then select Build | Build All and give it a minute or so to build everything. |
Set up symbolic links to the libraries you’ve installed above.
This will tell the mono runtime where to load the native libraries from. You will need at least
portaudio
– the latter is only required if you want to use the USB dongle.Run it.
Head over to the
sdrsharp/Release
directory and run:edit: Eric Brombaugh pointed out the following:
- The Mono and IDE suggestions you made are fine for those running newer versions of Mac OS X. I’m still on 10.6.8, so I had to install older versions of Mono and MonoDevelop.
- With the older versions of the .net tools, the SDR# .sln file wasn’t recognized, so I had to back off the version number in the .sln file by editing values in the header.
edit: Increasing performance
Sdr Radio Download
You may try your luck by precompiling the executable with
mono --aot=full -O=all SDRSharp.exe
. This will prevent the mono runtime from executing its JIT compiler, potentiallyleading to increased performance (it appears to help on my old Mac Mini, but YMMV). You’d then run the binary with mono SDRSharp.exe
- the precompiled code will be executedautomatically.edit: SDRSharp goes closed source
The author of SDRSharp decided to close the source for the software – if you’re okay running an old version (from September 2013), then you can get those sources from github.Instead of running
svn co
above, do the following:Sdr For The Machine
I’ve attempted to run the latest binaries with Mono, but did not succeed.
