If you have a general question about RTL-SDRs or SDRs or third party software we ask you to please ask in our forums. If you email us we may not respond to questions about third party software as this should be asked in the forum.

hello Admin
I recently placed an order for the RTL-SDR V4 from your official website and completed the full payment, including shipping charges, for delivery to India. However, I have been asked to pay an additional amount for shipping.
Since I had already covered the shipping costs at the time of purchase and was the consignee, I would appreciate clarification on why these extra charges are being requested. Kindly let me know if there has been any misunderstanding or if any additional steps are required from my end.
So I purchsed a RTL-SDR V3 R860 RTL2832UUSB dongle from Amazon. Then I tried ti install the airspy software following the instructions here and in the airspy website. Nothing seemed to work! I can’t get the drivers installed via Zadig it always errors out with “The driver installation failed” “Resource already exists” as this did not work, I have even watched and followed several you tube videos to get this to work and nothing works!!! I have spent days trying to get this up and running with no success! I am pretty tech & PC saavy. I can’t believe at this day and age this is so difficult and frustrating to get up and running!!! Also there is no clear information on which exact software to use for airspy. My PC is a Robo & Kala 2-in-1 Laptop with 64 bit Windows 11 pro. and a Snapdragon 8cx Gen 3 ARM-based processor. Can anyone help? this is driving me frustratingly nuts!!! 😡Thank You in advance! 😉
Thank You! 10 days from China to my doorstep on the East coast of Canada. That is express in my books. Thank you very much for the pleasant and efficient business transaction!
yup the debian driver install did what I figured it would, not work and render any other rtl-sdr I have unuseable
I’m having issues with RTL-SDR working with SDR Console. It works fine for a while, then I lose all of the signals. If I switch to another sdr decoding program (say SDRPP or SDR#) the dongle works. When I switch back to SDR Console, sometimes it works, other times I receive no decoded signals. Is there a known issue with compatibility of the dongle with SDR Console?
Windows 11 Update is likely killing your drivers. Try reinstalling the drivers once more and then update your registry with these settings.
Windows Registry Editor Version 5.00

Hi Paul
Thanks for the suggestions.
Oddly enough, after the last Windows 11 update, magically the dongle started working, and it’s been working flawlessly ever since.
Wonderful!
Lower gain on Linux Mint.
I have the RTL-SDR V3 and V4, and I’ve always used them on Windows (8 and 10). However, after several tests, I noticed that the gain of both the V4 and V3 is lower on Linux Mint compared to Windows 8.
I’m using the latest version of rtl-sdr. I’ve done all the tests, including using rtl_fm.
I’ve already uninstalled and reinstalled all the packages. Any tips? Soapy and libusb are updated.
One of the large antenna in my dipole kit broke. Is it possible to get a replacement?
If it was a manufacturing issue that caused it to break we can replace it under warranty, just email us at admin
rtl-sdr.com with your details. If it was broken to carelessness we can’t replace it, but we do have the antenna kit by itself available for sale. It’s currently out of stock, but it will be back in about a week.
Thank you, I sent a reply. One of the legs pulled out from the rest of the antenna. It was always looser than the other one. I just want a new leg and not the entire kit.
