libhomeradar

This example will only connect to the Airnav Systems Radarbox and will send all contacts to our collector (collector.libhomeradar.org port 8080)
After 16 contacted aircrafts (limit of the internal queue) the library will stop sending and inserting messages because no callback our queue readout function is registered. A good idea is to add a FULLQUEUE handler.

Data sharing is not legal in every country. Please check this before you enable this option.
You have to assume total responsibility on the consequences of sharing your aircraft contacts
