Thanks for the Info Wayne!
There is a Python API on the QS1R Website which I guess doesn't help much.
There is also the C source for the ExtIO.dll for use with HDSDR for download.
I'm not sure if that would help. Documentation is a bit sparse though.
The Python API and ExtIO including Source are here:

I'll see if I can borrow a Funcube dongle to play with for now.

The SDR hardware that WriteLog V12 has been tested with, so far, are
funcubedongle (http://funcubedongle.com)
SoftRock Ensemble RX
(http://fivedash.com/index.php?main_page=product_info&cPath=2&products_id=8&zenid=91abc70e77fb928899c13bd46c5459f2)
For WriteLog to display an SDR spectrum from a given SDR, it needs these two
things:
a) the time domain IQ stream. WL currently gets the IQ data via the Windows
Sound API, or, in the case of the FlexRadio devices, via WriteLog's rig driver
for that particular radio. If "time domain IQ steam" sounds mysterious to you,
think of it as digitized audio, required to be in two-channel stereo and you'll
have pretty close to the right mental picture.
b) enough information from the SDR to calculate the SDR's center frequency. WL
currently gets the center frequency one of three ways: (a) its fixed--you type
it into WL's SDR setup wizard or (b) the ExtDLL interface used by
http://hdsdr.de and others or (c) a WriteLog rig driver--currently only the
FlexRadio driver. If "calculate center frequency" sounds mysterious, think of
an SDR as being a "mixer" in the sense of a superheterodyne receiver (that
device you likely had to know something about to pass an amateur licensing
exam; it has two inputs: a local oscillator and a signal of interest.) WriteLog
has to know the frequency of the oscillator input to the mixer.
For most SDR applications, by the way, the software needs to know a couple of
other things that are not on WriteLog's list, e.g. the actual frequency of the
signal of interest, and its modulation mode. WriteLog doesn't need those
(currently) because it presents only the spectrum on its bandmap.
We are willing to entertain requests to support other devices that have other
interfaces. A quick read of the QS1R website shows the statement "we write our
own software" which might imply, but does not necessarily mean, they have no
open interfaces to (a) and (b) above.My quick browse did not turn up any API
documentation on that website.
