Hi ben,

Thanks, glad you like the scanner although I realise it's a bit of a 
pain to install all the dependencies under Windows or OS X.
I intended the software to be used to find interesting signals, which 
you could then analyse in other software, never really as a spectrum 
analyser (the thought of implementing all the maths gives me a 
headache!). Once I've found something I often use sdrsharp to 
investigate it and if I'm still interested I move onto GNU Radio.
I would really recommend you try GNU Radio, although you may find it has 
a steep learning curve. For example you could use VirtualBox 
(virtualbox.org) to run an Ubuntu machine on your desktop (compiling 
under Windows can be tricky) . There's plenty of information on both 
virtual machines and GNU Radio installation around.

Good luck,

> I've dreamed about building something similar for an RTLSDR, but much fancier (ping-pong on 'interesting' chirps, yo-yo sweeps to find voice/burst comms, trended plots etc etc). A poor man's wideband spectrum analyser. But I can't code to save my life..
> However, wait long enough and funny things happen :) You've made a great start with this project, especially given there was NOTHING out there prior (that I've seen anyhow. Certainly for Win32.)
> All the module/package dependencies are a bit of a pain but hey, you've got a working app :)
> Love to try it soon when I get a chance, hope you develop it up into a full-bllown RTLSDR spectrum analyser / "interesting signal" finder!
