RTL2832U-based DVB-T dongles are now supported by Gqrx SDR, see this announcement!
You may have noticed the recent buzz on the internet about using cheap DVB-T dongles as software defined radio receivers. It all started on this mailing list when V4L/DVB kernel developer Antti Palosaari discovered that the ezcap EzTV 668 DVB-T/FM/DAB USB dongle, which is based on the RTL2832U chip, can be used to stream raw I/Q samples to the host computer. It is in fact the way the device supports FM and DAB reception; raw I/Q is sent to the host where the application does the demodulation.

Just a quick note that Gqrx now uses pulseaudio for all audio I/O, which includes I/Q input from the Funcube Dongle.

I am happy to inform all users of the Funcube Dongle and GNU Radio, that the gr-fcd driver is now included in the GNU Radio source tree. You can read the announcement here.
This change will be available in the next GNU Radio release, which I think will be 3.5.3, however, if you pull the code from the GNU Radio git repository the changes are already in your tree. Before you upgrade please remove any earlier installations of gr-fcd to avoid conflicting versions of the library.
My repository on Github will no longer be maintained and any future development of gr-fcd will be done within the scope of the GNU Radio project. I hope this will ensure better integration, more maintainers, more testing and easier installation process.

Please visit the new Gqrx website. The information on this page is no longer updated!
Gqrx is a software defined radio receiver for Funcube Dongle (FCD), RTL2832U-based DVB-T devices (RTL-SDR), Universal Software Radio Peripherals (USRP) and Osmo SDR devices. It is powered by GNU Radio and the Qt GUI toolkit.

About a week ago I resumed working on GQRX – an experimental AM/FM/SSB software receiver powered by GNU Radio and using Qt for user interface. This time, however, I am not going to continue working on the Python receiver but create a new receiver from scratch written in C++. It will support Funcube Dongle and USRP/UHD devices.

This is the last satellite reception of a series recorded on Monday, February 28, 2011 using the Funcube Dongle software defined radio receiver and the Arrow II hand-held satellite antenna. The satellite is the good old Fuji FO-29 and the recording was made in JO45KG during orbit 71777.

This is the seventh satellite reception of a series recorded on Monday, February 28, 2011 using the Funcube Dongle software defined radio receiver and the Arrow II hand-held satellite antenna. The satellite is HO-68 / XW-1 and the recording was made in JO45KG during orbit 5791.

The Qt-based Funcube Dongle Controller is now also available as a windows binary package – thanks to Mike Willis G0MJW and David Barber G0OQW who have been trying to build it until we eliminated the two build issues (one of them was my fault 😉

Qthid 3.0 – the Qt-based controller application for the Funcube Dongle – has been released. This release includes support for the full control API available with the 18f firmware for the Funcube Dongle. This should cover all the functionality provided by the “fully functional windows front-end”.
