Yes, the FCD will not quite provide enough data for it ... It's more
aimed at very wideband SDR :p

It currently processes data in chunks of 128 * 1024 which for the FCD
is pretty big.

In lib/base_sink_c_impl.cc , look for "128*1024", there should be 4
matches, and replace them all by 16*1024 (you can't process less than
that).
It should improve the frame rate for very low sample rate.

Cheers,
