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 640×480 (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 (Howto)
  • 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)



  • fully integrated band management (ITU 1+2+3)
  • FreqMgr: HFCC frequency list (import)
  • FreqMgr: Perseus frequency list (import)
  • FreqMgr: FindMatch consider Time, AutoFindMatch
  • band selection / frequency step on main window
  • Misc option: Auto-LO
  • Misc option: keep Tune when LO is changed
  • Auto Band Zoom (Options -> Visualization -> RF)
  • Mouse Wheel option “Zoom RF”
  • Forwards button for WAV files
  • WAV buttons << and >> operate without WAV file { left click: Band +/- } { right click: Tune +/- step }
  • auto subdirectories for recording
  • more options for digital mode application (Options -> DigiMode Settings)
  • more command line options (-lo, -tune, -mode, -rec with recording time)
  • drag and drop for wav files
  • split for TX (SDR-TX only!)
  • slow speed for AF display
  • Autosave AF waterfall {CTRL+Shift+X}
