[UPDATE] Testing Boar Server. This is the final revision to the WebSDR. If your been following this development you will have noted that all of the popular servers have been at one point experimented with. Those include "Airspy", "OWRX/Kiwi" and now de Boer.

[UPDATE] NEW WebSDR Server. Now stream directly to your Phone, Tablet or Computer. Simply head over to http://AlphaMikeDX.ddns.net

Currently in working progress, but there is a "NEW" 11m WebSDR online at my home QTH. This SDR is running under the AirSpy Server protocol. This type of SDR "Can Be" a more advanced way of operating a WebSDR, usually having more sophisticated controls and options than a typical web based SDRs running in a "Internet Browser".

Frequency Coverage 26.500 - 28.000 Mhz (Bands LOW, MID, HI & UK40)
Server Name: (Alpha Mike DX SDR-081) or (26AM081)

How to Connect

Firstly your going to need the SDR Studio client to operate the WebSDR. Download the AirSpy SDR Studio Here: https://airspy.com/?ddownload=3130 (Currently only supporting Windows platforms, But VM ware or Wine is an option for Mac and Linux users)



Note you may need to download the .Net 5.0 from the Microsoft website before the application can run. You maybe prompted to do so upon executing the app.

Alternatively you can download this from the following link: https://dotnet.microsoft.com/download/dotnet/thank-you/sdk-5.0.200-windows-x86-installer

After Downloading

Once you've downloaded, simply unzip the file and run the SDRSharp.exe (no installation is required). You now need to find the online SDR's. Firstly go to the "Sources" Window in the lower left area of the application and select "AirSpy Server Network" (if you know the URL, you can simply paste it in the address bar).



Alternatively you can either click on the 3 dots to the right of the address bar to find the WebSDR or goto https://www.AirSpy.com/Directory/ and search for the URL ( Listed at the top of this post as Server Name )

I have now finally chosen the server to be used, it's been an interesting journey experimenting with all the different types of servers available. But the de-Boer system is the one that everyone seems to like the best, so we're sticking with that. 

Thank you to everyone that has helped with testing and reporting issues to improve the performances across all the servers used.
