Hi Vanush,

It uses the gr-osmosdr GRC block and the Funcube Dongle Pro+ is second in
the list of compatible devices so yes it will work:

http://sdr.osmocom.org/trac/wiki/GrOsmoSDR

However, In order to work using the 192KHz bandwidth of the Funcube Pro+
you will need to fiddle with the sample rates and make sure that they are
something like the following:

1) samp_rate = 192e3
2) channel_samp_rate = (quad_samp_rate * 1)
3) quad_samp_rate = (audio_samp_rate * 1)
4) audio_samp_rate = (48e3)

I'll update Scanoo to have an option in the GUI for the 'channel_samp_rate'
and 'quad_samp_rate' multipliers for easy Funcube use and better
flexibility. Thanks for asking the question!

Regards,

Mike
