Hi Alexandu,
Oh yes, by plugging it into an audio source it will work as is with GR.
We wonder how to rip the I and Q's and pass them further to GR for
(de)modulation
We need to study the dongle and its ICs more
Thanks,
Patrik

Hi All,
Has anybody tried the FUNCube USB dongle?

How tricky would it be to add GNU Radio support for it?
Hi Patrik,
The FCD works as is with GNU Radio since it is an audio source. I used
GNU Radio for my initial tests:
http://www.youtube.com/watch?v=daY-fkMYN_M
Changing frequency can be done using the qthid control application.
The one on the website is known to crash and freeze. I have since
forked it and applied the necessary fixes to make it run stable. It is
available here: https://github.com/csete/qthid although not quite 100%
stable unless FCD is running the 18f firmware.
Once I'm done with this I will implement the remaining API for setting
gains and filters and eventually there will be a "libfcd" which can be
included in a GNU Radio block.
I'm not sure if it makes sense to create a GNU Radio block for this
since the FCD is already an audio source and a block is not necessary
for setting frequency and such. I guess it would still be useful for
using it in GRC applications.
