HDSDR VERSION 2.80 BETA RELEASED

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).

After a long hiatus, development of HDSDR got going again in early2017 with versions 2.70 and 2.76, followed by 2.76a in March 2018. Now, version 2.80 is outin public beta, and there is every reason for HDSDR users to upgrade. The upgrade is a mix of new or enhanced functions, and a modest (as always) change to the graphical user interface (GUI).

I have talked with the team for the last year or so and sent a few suggestions which would improve my use of HDSDR. I’m happy to see some of them well taken care of, and otherchangeshave beenaddedtoo.Graphical User InterfaceIf we start off with the visual appearance,the lower left “Control Centre” if you like, has been rearranged a bit. For the first time since the Winrad days, the mode controls are different with the indicator “lights”moved below the text, allowing for smaller controls so the FreqMgr function could move up.

Also, the ExtIO function was moved to the F column to the left, renamed and assigned to the F8 key. Help/Update has been removed, but no worries, if you press F1 it’s still available. All this reshuffling opened room for two very useful additions: The Frequency Band selector, and most important of all in my view, the Frequency Step selector, which has moved away from its convoluted position within Options. Moreover, the Frequency Step (tuning step) function is now preassigned by band, so if you tune a SW broadcast band the default frequency or tuning step is 5 kHz. On MW, it’s 9 or 10 kHz depending on which ITU zone you have assigned in FreqMgr. One thing I particularly like with HDSDR is that the tuning steps are not mode-dependent.

Another newfeature is that during playback, frequency and mode are displayed together with the file data. Now why would you want that, with the information already available just above? It is because blind users are not able to see both the frequency and the running time simultaneously. By adding frequency to the same line, they can. Universal design
