SDR and Unitrunker

I've been interested in software defined radio for a while now and I've been using a wonderful application called Unitrunker to listen to my counties trunked radio system. To help others do the same I've created a how-to which walks you through installation and calibration. Check it out:

OS X Location Information: Where Has That MacBook Been?

Image
Readers may remember small tempest created when the consolidated.db (later renamed) file was discovered in Apple’s iOS tracking the phones location information. As it turns out, much the way the consolidated.db file tracked the location of WiFi access points and mobile towers around the iPhone, there is a similar file included as part of OS X Mavericks and other recent versions of OS X.    Hidden deep in /private/var/folders lies the file cache_encryptedA.db. Tucked away with, an often empty, consolidated.db and other files, cache_encryptedA.db tracks information about WiFi access points located around the Mac as it moves around. Data includes: WiFi Access Point (WAP) MAC Address  Latitude and Longitude  Time Stamp Data WiFi Channel Information Assuming Location Services is turned on and used (by the Maps app for example) the database should look something like this: The WiFi access points found in the database don’t necessarily reflect t

Apple Location Service Seed Database

The file is located in: Macintosh HD/System/Library/Frameworks/CoreLocation.framework/Versions/A/Support/ The WifiLocation table holds MAC addresses, Latitude, and Longitude information. Other tables may be worth exploring as well. Since this database does not seem to track the location of the device this database is of little use to most people though if you live around an airport it may be interesting to see if your WAP is included.
