Funcube Dongle support now built into GNU Radio

Funcube Dongle close-up

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.

GQRX C++ Edition

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.
