What is HDSDR?

 

HDSDR is one of my favorite SDR software applications. It's easy to setup and fun to use. From the HDSDR website, HDSDR is a freeware Software Defined Radio (SDR) program for Microsoft Windows 2000/XP/Vista/7/8/8.1/10. Typical applications are Radio listening, Ham Radio, SWL, Radio Astronomy, NDB-hunting and Spectrum analysis.

 

HDSDR (former WinradHD) is an advanced version of Winrad, written by Alberto di Bene (I2PHD).

Main features:

  • Separate large spectrum and waterfall display for input and output signals
  • RF & AF spectrum and waterfall is optically zoomed to fit window width independently of FFT resolution bandwidth (RBW)
  • Flexible and efficient usage of the screen area from 640x480 (Netbooks) up to unlimited
  • Extreme low-speed waterfall - helpful for pattern noise detection or short wave condition monitoring
  • AM, ECSS, FM, SSB and CW demodulation
  • Basic transmit (TX) functionality in modes SSB, AM, FM & CW
  • I/Q modulated signal pair for the TX input signal (Microphone) is produced on the TX output
  • Squelch, noise reduction, noise blanker, adjustable band pass filter, anti-alias filter
  • Automatic notch filter and up to 10 manual adjustable notch filters
  • Record and playback RF, IF and AF WAV files with recording scheduler
  • Frequency Manager for Eibi, Ham Bands, Radio Bands, User frequency lists
  • DDE client for Ham Radio Deluxe, Orbitron, WXtrack, SatPC32 and Wisp (How-to)
  • Omni-Rig support (CAT) to control additional hardware
  • Support for various hardware through Alberto's (I2PHD) ExtIO DLL interface
  • ExtIO frequency options for IF-Adapter, Upconverter, Downconverter, Undersampling and calibration
  • All HDSDR program options can be stored and loaded per "profile", to ease use of different receivers
  • Autocorrelation and cepstrum display for demodulated audio
  • Command line options "-as"(auto start), -fs" (full screen)
    "-swapsw" (swap spectrum/waterfall display), "-p profilename" (profiles)
