qrh-OS

Your Ham Radio World,
Inside Windows.

An application that works simulating an operating system inside your Windows 10 or 11 system. An evoluted launcher. It does not change your system settings: it adds a virtual desktop with utilities for amateur radio operators and an integrated CAT radio system, and now RTTY and WEFAX reception with easy signal alignment, plus CW (Morse code) decoding.

Simulating an Operating System.. this is an evoluted interactive launcher.

qrh-OS brings radio utilities, live maps, web pages, audio and video players, DX tools, and now RTTY and WEFAX reception together in one focused environment. The new reception tools include an easy system for aligning to received signals, and qrh-OS can also decode CW (Morse code) transmissions. With many additional utilities for amateur radio operators and technology enthusiasts, everything runs in a single window inspired by classic Windows systems—directly on your Windows 10 or Windows 11 PC.

The author chose to call this application qrh-OS because of its interactive features and built-in multimedia capabilities. It is not an operating system, but a valuable launcher—a powerful utility that runs on Windows 10 and Windows 11.
