Alternate RTL2832U Install for SDR-Radio.com

sdrcom2

Since the original article was posted on using the RTL2832U DBT stick with SDR-Radio.com, one of our readers (Jeff) pointed out that some new .dll files have recently been made available that will allow you to more easily use a RTL2832U stick with SDR-Radio.com. The biggest advantage of the of the new .dlls’ is not having to use SDR-Radio.com with the rtl_tcp TCP server. This allows you not to have to start the server every time you use SDR-Radio.com, plus SDR-Radio.com starts processing data from the RTL2832U much faster. The other advantage, is that it does make installing the RTL2832U for SDR-Radio.com a bit simpler. These .dlls’ were not developed by Simon (SDR-Radio.com author) but by a third party AA5SH and can be downloaded directly from his website. I did a quick test of the new .dlls and they seemed to work fine. You can choose to continue to use the TCP server, which might come in handy to stream data from a RTL2832U to a remote copy of SDR-Radio.com, or you may want to give the new .dll method a shot. Heres how to use the new .dlls':

  1. Download and install the latest preview version of SDR-Radio.com.
  2. As usual download and extract the latest Zadig drivers and install them for your RTL2832U stick. Remember you need the 7Zip software to extract Zadig.
  3. Download and extract the .dll files from AA5SH website.
  4. Open the folder SDR-RADIO.com.RTLUSB that you extracted. There will be two folders 32bit and 64bit. Open the folder that matches your Windows version (32bit or 64bit). Copy the three .dll files contained in the folder to the SDR-RADIO-PRO.com folder on your PC (usually found in your Program Files folder).
  5. Start the SDRConsole.
  6. Click on the Radio Button near the top of the console.  Add a radio definition.  Be sure to change the radio type in the drop down menu to RTL SDR (USB). Click the Search button and if everything is installed correctly SDR-Radio.com will find the RTL2832U. Click OK and your stick should show up in the radio definitions list. You can also select the sample rate at this point if you want to from the drop down in the radio definitions box. Highlight the RTL2832U device in the radio definitions list and click start.
  7. You RTL2832U should now be running with the RTL2832U stick.
  8. You may want to adjust the RF gain setting from the RF menu at the top of the SDRConsole screen.
  9. You also want to click on the More button at the top of the SDRConsole and set the PPM offset to have SDR-Radio to more accurately display the tuning value from the RTL2832U stick.

Thats it. Enjoy!

    Nice work! Everything appears to work except I cannot get any sound. The speakers are not muted. SDR# works fine with speakers. Any suggestions? I’ve checkedand I couldn’t find out what was keepng the noise from the speakers.

    thanks for the help,
    I’ve ordered a dongle from Ebay, £8 including posting!
    from what my friend G1VVP tells me i’ve resigned myself to the fact that it will overload at home.
    but i do a lot of dxpeditioning and i don’t feel so anxious about taking an £8 radio and old laptop abroad as i would with a £3000 comms rx!

    i’ll review the Dongle from the Radio Quiet Zone at Jodrell Bank Observatory when it arrives, and if theres still problems i’ll try a Country road i know
    and if its still unusable – what the heck its only £8!

    i got SDR-radio 1.5 build 1058 here….

  4. ton muller says:

    nevermind…
    wrong software…..

  5. ton muller says:

    ok, is there a option to set the osc offset ?
    my RTL stick has 6khz mismatch on narow frequenties

    • HRS Staff says:

      Yes, most of the SDR programs offer a PPM setting or an offset setting for dialing in the receiver frequency. You just have to hunt down that feature depending on the software you are using :)

  7. Zdicieck says:

    Got sdrsharp working with the dongel, wanted to try Simon’s SDR-Radio. Got the dll’s from AA5SH website just fine.
    Must be getting old but no download link on SDR-Radio.com for any version.
    Any one have a link?

    Nice demo (2.0 build 1361 64) in an alpha state but not more. Consumes huge amounts of memory, sound card not really selectable, hang-ups, multi VFO option not working, frequency not shown correctly, grafical window overlapping problems.

    When I use the rtl2832u+r820t with the v2 console, it lags up the computer and runs extremely slow and the audio is choppy, in and out. Other software allows you to adjust the audio sampling rate and speed of the spectrum, from slow to stop, and it frees up some ram to run smoothly. But I can figure out how to reduce anything to get the software to perform without sluggish behavior. It demands so much on the computer, using it is not fun.

    I tried downloading the AA5SH RTL USB ZIPS from his site but when i unpack / unzip them they keep displaying corrupted.

    Tried several downloads and various unzip packages – same errors.

    Any one got a good copy they would share / send to me?

    Any help would be much appreciated …

      The author contacted me and indicated the files were corrupt. He uploaded new ones and they worked Perfect!

      Thanks

    It keeps saying “nothing found” when searching for the usb radio card. Windows shows it fine in the device manager. Can anyone help? Thanks.
