macOS Server App For AirSpy HF+ SDR

This app lets you run your AirSpy HF+ on your Mac, in macOS, without the need for Windows!

It only works with the AirSpy HF+, no other AirSpy versions, as I do not have any other AirSpy SDRs to test with.

It works with SdrDx, which IMHO is the best SDR app out there for the Mac. SdrDx can be downloaded from:

Please note, I cannot help with general questions about the use of SdrDx.

Plug in your AirSpyHF+

Download a copy of the server app (download link at the botton of this page). Unzip (if needed) and run the app.

To use this app, you need to have libusb installed. If you do not have it installed, you can do so as follows (at your own risk, of course!), using the terminal:

If the directory /usr/local/lib does not exist, create it:

sudo mkdir /usr/local/lib
Then copy libusb-1.0.0.dylib, included with the download, to /usr/local/lib:
sudo cp path_to_blah_blah/libusb-1.0.0.dylib /usr/local/lib/
Run the server. If your Mac complains it can't open an unidentified app, right click, select open.

When you run the server app, it should look like this. If you get an error that it could not find the AirSpyHF+, you'll need to figure out why. Maybe it wasn't plugged in?

Then you need to go to SdrDx and configure it to use the server. You need to do two things.

First, click the NET button (low left part of the SdrDx window) to bring up the network settings, and check the box "Just use". Also make sure the SDR TCP Port setting is the same in the server app, 50000 is the default value:

Click OK. The bottom of the SdrDx window should display AirSpyHF+ Connected in big green text.

Also, the server app should now say it is connected:

Then you need to click the SDR button (also lower left part of the SdrDx window). In the SDR Setup, you need to do a few things:

Under custom settings, set the Sample rate and Bandwidth both to 768000. As of now, the AirSpyHF+ can only sample at 768 kHz.

Then check the Custom Grid Spacing, SR BW checkbox below that:

Click OK.

You should now be able to click the Run button, and enjoy the AirSpyHF+ running under SdrDx on your Mac, without any need for Windows.

Looking for a great SWBC/DXing app that also is integrated with SdrDx, but also works stand alone for any DXer no matter what radio? Take a look at Dx ToolBox which is available for both Mac and Windows.

Download the AirSpyHF+ macoS Server - Requires macOS 10.6 through 10.13
