QIRX3

QIRX3 by softsyst is a modern software-defined radio (SDR) application for Windows, built for high‑quality reception and in‑depth analysis of broadcast signals, with a strong focus on DAB/DAB+. It combines a responsive interface with advanced signal‑inspection tools, making it useful for both everyday listening and technical work.

QIRX3 delivers real‑time DAB/DAB+ demodulation and decoding, showing ensemble and service information, audio, and—when transmitted—visual content. It also supports transmitter identification through TII, helping users map and verify coverage. Engineers and hobbyists can explore spectrum and waterfall displays, constellations, impulse responses, and channel metrics to understand multipath and signal quality.

The software works with popular USB SDR front ends as well as network‑based SDR sources, supports IQ recording and time‑aligned playback, and can observe multiple inputs for comparison and logging. Its 64‑bit, multithreaded design provides smooth visuals and reliable long‑term operation.

Highlights:

Typical uses include everyday DAB listening, coverage surveys and transmitter identification, band scanning, spectrum monitoring, and educational or lab work in digital radio.

Availability: QIRX3 is offered for 64‑bit Windows. For installation steps, supported hardware, and license terms, visit the developer’s website. more
