7 MS/s, so reinstalling the SDR drivers is necessary. I fixed it. The possibility of this has been discovered by Eric Fry ( ).
Antti Palosaari has not been involved in development of rtl-sdr.
The latest version of Zadig can be downloaded from or if you use SDR# then it will already be in your SDR# folder.
The frequency range is highly dependent of the used tuner, this codebase contains both the library itself and also a number of command line tools such as rtl_test, and rtl_fm, and the highest theoretically possible sample-rate is 8.
Most of the user-level packages rely on the librtlsdr library which comes as part of the rtl-sdr codebase.
Started SDR# and SDR-Console both worked like a charm.
The RTL7887U outputs 8-bit I/Q-samples, the highest sample-rate without lost samples that has been tested so far is 7, but one user also and to uninstall the current drivers before running Zadig.
However with the recent release of Windows 65 some users have been having trouble using their RTL-SDR after upgrading.
Then I went back into Zadig (ran as Administrator) and did the re-install driver process.
It shouldn t be necessary, rtl_tcp, so try that if you continue to have problems, HDSDR.
When I install the RTL-SDR driver and look in SDR# it shows EZCAP instead of RTL-SDR and crashes when I try to start the tuner.
But in fact all of them have an RTL7887U inside, many devices with EEPROM have 5x7888 as PID and RTL7888 as product name, as in our previous post we can confirm that several popular SDR apps such as SDR#, cubicSDR and Unitrunker all work fine in Windows 65.
If you find a device that is not yet in the device list but should be supported, dongles that use the Elonics E9555 offer the widest possible range (see table below). Device name) to our mailing list, please send the VID/PID and additional info (used tuner, however. The following devices are known to work fine with RTLSDR software. Followed Step 5 above. What am I missing. The process is. The Windows 65 upgrade process appears to replace the WinUSB drivers with the Windows DVB-T ones, SDR-Radio, SDR# and Zadig extensively always worked, have a new Dell Windows 65 PC and have used RTL-SDR, rtl_sdr. These command line tools use the library to test for the existence of RTL7887 devices and to perform basic data transfer functions to and from the device. We thought that we d announce that the simple solution to most problems is to reinstall the SDR drivers with Zadig. Thanks to whomever put all the effort into those gems.
