Glad to hear you got it working.  Not sure what the threading error was but when I get time I'll try it on the Pi.

The scan will speed up if you reduce the dwell and FFTvalues, but it's a shame to reduce them much below the defaults.  The scanner spends most of it's time performing Fast Fourier Transforms, on desktop systems each FFT is performed on a sperate core but as the Pi has only one processor only one process is run at a time.

The other option with a Pi is to use it as a remote server with the dongle, you can then stream data to another machine.  Start the server on the Pi using:

rtl_tcl -a <ip address of the Pi>
