    Lol thanks I ended up getting HDSDR to work but the reception is garbage i think the sdr i have is junk. Or there’s something i dont know about the antenna setup. I just have a cable with striped end i hooked an ariel to. 😜 i know every other radio i have works much better than the rtl so far.

    It is now such a complex software that discovering cold fusion is easier. I believe people who use and are able to install it belong so some sort of masonic lodge composed by no more than three members.

    I am running windows 7 ultimate 32 bit and cannot get the winusb driver to install with zadig. It shows none for driver installed and allways Driver Installation: FAILED (other error). Ive tried everything i can think of. Please help.

    Over time, SDR Sharp has become more bloated and difficult to install with each successive
    version. Now Windows 11 is here, on both X86 and ARM based systems and I’ve been trying for several days to get Zadig and SDR Sharp working with my RTL-SDR/820T USB dongle. Everything worked fine in Windows 10 64 bit. The folks at AirSpy need to come up with a COMPLETELY NEW installer that just does everything as far as installing drivers, configuring them, etc. Too many hoops to jump through getting this software to actually WORK, when there are so many other software packages out there that work without all of the fussing and fidgeting around with drivers, having to read tutorials, watch videos, config stuff, etc. All the user should have to do is plug their RTL-SDR into a USB port and run the installer – ONCE. Release an installer that can do this and you WILL sell more product.

    Hey all, I noticed some of the comments after having issues myself with setting up for first-time use and I ended up connecting to my VPN. I had issues running the .bat file and the URL getting blocked. The comments are right with your anti-virus or maybe your router security blocking the URL. If you connect to a VPN it will bypass this and everything runs as expected. It makes it easier than messing around with your antivirus or security settings. Hope this helps.

    I abandoned this program months and months ago because it had become something for a restricted circle of software gurus, people who like to spend hours and hours during the night trying to fix the unfixable. If SDR isn’t widespread this is the reason. Unless you have three degrees and a Masters plus a Ph.D. in software development, the software will never work.

    Ansolutely!!!!!!!!!!!!!!!! Can’t these guys hire a software expert? Most average users can’t make this work. Sale would go up if it were easier to get working.

    My antivirus flags the file URL as containing a file with Win64 malware, this first time. After that, the antivirus blocks the URL completely and makes it appear like a dead link. If I turn off antivirus, it goes to URL and downloads, but then I’m vulnerable if it does have malware. I went to the URL and downloaded the .zip file on my Android phone, then emailed it where I could get nit to the PC. Interestingly, gmail wouldn’t let me send it.

    Links are dead. I’m not going to multiple websites to pick up multiple files to correct a failed installation. All of this should be included. Installation fails on a clean copy of windows 11. This is going back to Amazon.

    Yo all , what the f.. are wrong wit all you? That link doesnt work, its imposible to even get the files on the whole internet !! Can please someone just upload it somewhere ? Will pay for it, no cap!

    It appears that the osmocom link for RelWithDebInfo.zip is dead.
    I can’t seem to find it anywhere, but I might need to look on some of my older computers.

    Very difficult to configure the SW and the users guide seems to encourage installation of extraneous, not needed SW rather than give simple installation, configuration instructions. The media player does not work, and why do I need someone else’s anyway? Frustrated but not totally stupid. Ready to return this; thankfully it was gift and I did not pay for it.

    Hello its dont work on Airspy SDR# (SDRSharp) x86 revision 1769 96aaa72b (2020-10-20) with the dongle https://www.ebay.de/itm/RTL-SDR-Blog-V3-original-RTL2832U-1PPM-HF-BiasT-SMA-Dongle/324123706220?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 and WIN7 64 bit the rtlsdr.dll is not customized for it. The scriptfile from Airspy rtlsdr.dll crash the airspy software,with the 64bit file ( rtlsdr.dll) from osmocom it started but i can not selected any dongle i hear nothing zadig was installed on hdsdr with the ExtIO_RTL2832.dll it works well. Its definitely the DLL File i hope your team can write a working DLL file best regards Chris Win 7 64

      I don’t think you should expect another version of ExtIO_RTL2832.dll for Win7. Win7 has been obsolete for quite some time now, causing problems with different versions of RTL-SDR programs. I have successfully updated all computers (> 5) to Win10 for some time now. You can still do the update for free (it is somewhat hidden), if you have a valid Win7 system. I have also found several ExtIO_RTL2832.dll versions (especially mod versions) that work with HDSDR and SDR #. I myself no longer use SDR #, although it has many possibilities, it does not give me quality reception. For that, HDSDR or SDR console is a much better choice. I would not choose the RTL-SDR V3 dongle (anymore) because it puts the tuner offside for HF reception, and uses direct sampling on the AD chip, which is insufficient to get good reception on HF, and is a very good antenna. required. The even better method to get good HF reception is to use an HF Up converter before the SDR. I have made 5 versions, and they work very well on my regular dongles.
      For the better work, and for about the same price as an expensive dongle, I have an RSP-1 or an MSI panorama stick. It has a reception range of 10Khz to 1.7GHz, and there is no need for direct sampling or an UP HF converter. The sensitivity and bandwidth are also a lot better. Grts, on1bes

    I found a solution that works for me after the update from Windows 10 to ver2004. I also had the problem that HDSDR would no longer start with the old EXtIO_2832.dll. It has nothing to do with Zadig. The latest Zadig 2.4 installs without any problem to add the RTL driver to the USB devices. But the last EXtIO_2832 no longer works in Windows 10. I looked for other DLL drivers, and found one that works with the modified divers for the HF Mod in HDSDR. I am now using the ExtIO_RTLSDR_u8.dll, and it works perfectly until now.
