General Share of Operating Systems

In the area of desktop and laptop computers, Microsoft Windows is generally above 70% in most markets and at 77% globally, Apple's macOS at around 13%, Google's ChromeOS at about 6% (in the US) and Linux at around 2%. All these figures vary somewhat in different markets, and depending on how they are gathered. From Wikipedia.

I personally dislike Apple and will never develop for macOS. Linux is OK but I’ve been there before and prefer Windows. As a developer on Windows the tools from Microsoft are superb, 

Operating System use in Gaming

There’s a reason Windows / Xbox is dominant in gaming, just look at this chart: Share of Steam (gaming platform) users in October 2019, by operating system used . 

DirectX is an amazing tour de force, something I want to master over the next three years.

Users by Browser and OS

This is a duda.co website running on Amazon Web Services (AWS). The site gathers visitor information, below is a breakdown by browser and operating system. Note: all website know the browser you use and your IP address.

Of interest is the ratio of Windows to Linux users, 16.75 : 1. Similarly the ratio of Windows to MacOS users is 13.5 : 1.

So there's absolutely no chance of a rewrite of this project for either Linux or or MacOS.

Sorry Folks...

Version 1.6.1 This release fixes two fatal bugs in the new DX Spot feature. When the graphics engine is restarted, resources are correctly released. Fixed a resource leak when processing the MoseMove logic.  Downloads are on the World Map page . Version 1.6 This release adds the display of DX Spots. Display spots are submitted to PSK Reporter which in turn are relayed by a MQTT Broker running on a high performance Akamia node. Spot Format Each spot consists of these fields: Sequence Frequency Band Mode Signal level Time stamp Sending station call, square, country Receiving station call, square, country Note: The country is the ADIF country. Spots are displayed as they arrive, currently no on-demand database. Bandwidth To reduce bandwidth from the broker, filtering is required for 80m up to and including 15m. Filtering requires at least one field below to be set in a definition: Receiver callsign, square or country. Sender callsign, square or country. Without filtering the bandwith from the broker could be excessive. For LF and VHF+ no filtering is required due to the lower number of spots sent on these bands. In a later version the bandwidth restriction may be reduced.

SDR Television v1.1 May 18th, 2026: This is the official v1.1 release , code exactly the same as 1.0.16 which has survived testing for a few weeks. Lots of improvements since the last official kit. As with any software project, there's always room for improvements and new features, but for now here's a stable solution which works well with the QO-100 satellite. Many thanks to Sigi and the DATV test team. Downloads are at the bottom of this page.

Follow These Steps If you're unsure how you add a radio definition to SDR Console, here are the steps you must follow. Start SDR Console (quite obvious really). From the Home tab on the ribbon bar, in the Radio panel click Select Radio , the Select Radio window is displayed. At the bottom right of the Select Radio window, click Definitions... , the Radio Definitions window is displayed. At the top left of the Radio Definitions window click Search , a list of all supported radios is displayed. Select the radio you want to add, for example Airspy, SDRplay. In this example the RX-888 will be added. When you select an option from the list in step 4, either a radio is found or not. If the radio is found, a window is displayed with the option of adding the new definition. If the radio is not found, an error window is displayed. If this is a radio connected by USB, make sure the USB port can supply enough power. After adding the definition, click Save in the Radio Definitions window. You can now select your radio in the Select Radio window. That's all folks! SDRplay If you are using a SDRplay you select SDRplay > V3 in step 5 above. Make sure you have also installed either SDRconnect , SDRuno or the latest API (currently 3.15 at the time of writing).
