QIRX 4.0.1

QIRX is a Software Defined Radio (SDR), written in C#. In its Version 4 it comes with many new features compared to the previous versions. DAB Marginal Signals: The decoding sensitivity has been significantly enhanced, now being at least as good as the best other DAB solutions. General GUI: The layout has been enhanced by a commercial window docking solution. This means that you can dock or float the most frequently used windows, like The map All three possible receivers All DAB spectra All "tabbed" DAB windows Examples where this is beneficial are On ADS-B, the map can show much more information on a larger screen, together with the tabular display, On DAB, the I/Q constellation spectrum can - independently from other displays - be kept quadratic when floating, On DAB, windows containing a lot of information like the CIR spectrum or the "Ensemble" table, can be inspected much more comfortably when presented as large floating windows. In addition to the fact that the complete layout is persisted, on the QIRX top menu bar a new button is provided to save, restore or reset a complete layout. DAB EPG: The program schedules received from the MOT EPG service are - where sent - available as a new tabbed window. The most attractive ones like the one of the BBC in the UK or the DLF in Germany are - among others - available. DAB Bit and Modulation Error Rate (BER, MER): The DAB measurement capabilities have been enhanced by BER (as usual, "pseudo BER") and MER, usually not being found in DAB SDRs. DAB I/Q Constellation: Likewise, the I/Q constellation now provides the measurements of a selectable single carrier or symbol. Map Range Rings: The selectable range ring distance can be selected as km or nautical miles (nm). ADS-B Map Display: Aircraft are now displayed together with their flight id. ADS-B Filter: The ADS-B map and tabular displays can be "decluttered" by applying filters. Possible filter values are Altitude Velocity Track Vertical Velocity Distance from own position The filter selection is synchronized between the tabular and the map presentation. Map vertical color bar for aircraft tracks: By comparing the track color of an aircraft with the vertical color bar of the map, a quick estimate of the aircraft's altitude can be made.
