RTLSDR Scanner Installation in German

Rudolf has made some notes and installation instructions in German which you may find useful.  The installation includes Ubuntu 14.04, OS X Mavericks (10.9.5) and Windows.

Thanks Rudolf

Heat MapI've added basic GPS functionality to the RTLSDR Scanner.

The idea is if you've set up a GPS device it will record the location of each scan which you can then create a map of signal strengths to view in Google Earth, a GIS (Geographic information system) or an image viewer.

Once you have added a GPS (Edit->GPS Devices) and enabled GPS logging (Edit->Preferences), simply start a continuous scan as usual.  As each sweep of the frequency range is performed your location is added to it.  Currently the most up to date location is used before the sweep ends, because of this I recommend only using narrow frequency ranges for accuracy.  You may also want to increase the number of scans that are retained (Edit->Preferences) so you have a large dataset to work with.

RTLSDR Scanner Installer

The RTLScanner now has an installer for Windows x32/x64 which will now download the program as well as it dependencies.  This should make the installation process fair easier.

The first time you run it, just accept all the default options and it will install all the software you need.  If you want to update the scanner (for example when I push some new code) just run it again and un-tick  'Dependencies',  the new code will be downloaded from GitHub and installed on your machine.

Just a word of warning, the installer updates your system PATH variable with the location of Python that it installs, this can cause problems with existing Python installs.

RTLSDR Scanner Multiprocessing

The RTLSDR scanner has been given a bit of an update behind the scenes.

It now analyses data using separate processes rather than threads which allows for far more efficient processor usage, as a result large scans are faster and the user interface is far more responsive.

Unfortunately I'm having problems with PyInstaller (which I use to create the binaries), as soon as this is fixed I'll upload them to Sourceforge.
