For some reason recently I wanted to build a log of all flights passing close to my house. You can't get this info from the database because that only logs the start and finish lat/long, so I decided I had to monitor the socket output.
I've built a little bit of VB in Excel to listen to the socket and track the range of aircraft, and log them if they come within a certain distance.
If anyone is interested I'll upload the file (it is clunky but works - only wish I know "proper" pc programming to make a real third party app!).
Cheers

PS this could also be adapted to monitor the lowest altitude achieved, greatest range at given altitudes, lowest elevation angle, range as a percentage of radar horizon (i.e. degree of blocking against azimuth) etc.
