As some of you know from my first post here then I am a newcomer to this forum and to the art of flight tracking, for these reasons I got a few questions, but first a line on my setup.
I build my receiver following the guidelines from the flightaware web site using Raspberry pi+, ADS-B receiver dongle, 16GB MicroSD card, WiFi adapter), the antenna that came with the ADS-B dongle (I know this antenna is not the best, but I had to start somewhere) running latest version of piaware. The whole build is located on my south facing terrace with a close to 180 degree line of sight to the sides and up. I have free line of sight to one of the final approach flight paths to the nearby airport.
Is there a log I can check each day that shows the flights tracked during e.g. the nights and/or evenings?
How come I see no squawks when I use the build in “tracker” accessed by the IP address of the box and :8080? I assume airlines from AA, TAM and so on uses squawk codes. See attched screenshot or can this only be decoded when accessing flightaware’s web?
How come I mostly see only higher altitude flights, basically none on the final approach, I have many fights passing right over the antenna, but the more lower ones are not tracked - is this normal, or must I do something?
How come when looking at My ADS-B page then the map is always empty - as per attached screenshot is this correct or?
Sorry for the long post!
