No, it is an SDR internally, with a self-contained User interface
and sound output that makes it a complete stand-alone radio.
It uses a PIC microcontroller and a DSP chip to perform
all radio functions, and the SW for both of these is upgradable.

Their Windows Spectrum display Software is irrelevant to
the I/Q protocol used on the USB port by the SDR.

Which is exactly what I want to do: Write a GnuRadio source
block. Hence, my first question is to see if any one has already
done this.  I've already put in a request to the manufacturer for
the details of the protocol.
