Following my success with integrating the frequency control widget from cutesdr into gqrx I have decided to try the same with the FFT plot and waterfall widget. This too seemed to be a single C++ class that might be easy to integrate into my experimental software receiver powered by GNU Radio and Qt GUI.

An awesome frequency control widget
Gqrx / C++ update June 4, 2011: After establishing the basic framework for a GNU Radio receiver written in C++ it was time to start working on the GUI framework. As you may recall the GUI will be written in Qt and I am hoping that it will simplify porting the application to Mac OS X.
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.
Simple APT decoder prototype
I have wanted to implement a simple APT decoder for the NOAA weather satellites in GNU Radio for quite some time now, in particular since the USRP equipped with a TVRX or WBX daughterboard and a GNU Radio FM receiver can be an extremely good receiver for this purpose. Today I have spent some time looking at the details of decoding APT and actually ended up with a working prototype implemented using the GNU Radio Companion.
FO-29 satellite reception with Funcube Dongle and Arrow antenna
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.
HO-68 CW beacon with Funcube Dongle and Arrow antenna
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.
Qthid 3.0 for Windows
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 with full API support released!
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”.
PRISM cubesat reception with Funcube Dongle and Arrow antenna
This is the sixth 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 Japanese PRISM cubesat an the recording was made in JO45KG during orbit 11343.
CUTE-1.7 + APD II reception with Funcube Dongle and Arrow antenna
This is the fifth 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 CUTE-1.7 + APD II cubesat – also known as CO-65 – and the recording was made in JO45KG during orbit 15341.
