What’s new in QIRX 4.1.1?  Abridged from  this QIRX history page.

  • QIRX was enhanced by a streaming server, able to re-distribute the raw I/Q data to several clients, limited by the necessary performance.
  • WFM has an RDS decoder.
  • The file replay of recorded I/Q data can be accelerated by GUI-selectable factors of 2, 4, 8.
  • The WFM demodulator now shows the selected peak SNR (Signal to Noise Ratio) as well as the power in dBm of the selected station, for the SDRplay receivers and the RTL-SDR dongles.
  • AGC of RTL-SDR:
    AGC off: The gain value is entered manually, via a slider on the GUI. Accurate.
    AGC on, SW checked: The gain value is controlled by the rtl_tcp(2) software. Accurate.
    AGC on, HW checked: The gain value is controlled by the RTL-SDR hardware. Not accurate.
  • The sorting of all the tables underwent a thorough revision, including an addition of the usual column sorting direction indication.
  • The multiplex overview table for DAB will get the additional column “ShortName” for the 8 character label of a service.
