It looks like a typical PlanePlotter setup.
The map outline showing on the right side and the aircraft listings on the left.
Yep - PlanePlotter it is
Simple RTL-based dongle, antenna pigtail so I can hook up to a BNC connector rather than the MCX that is on the dongle.
Total cost of set up (excluding laptop!) :
RTL Dongle $17 (down to $9 on Amazon now - in fact a $9 one should be arriving to me in the US today)
RS 800MHz antenna (borrowed from scanner) - $25
PlanePlotter software - $39
Dump 1090 software or RTL1090 software - free
With this setup I can view aircraft for over 200nm. My fixed station in Alberta has a greater range (has a roof-mounted home-made antenna cut for 1090MHz), and it runs PlanePlotter on an old XP machine that someone was throwing away!
BTW, that dongle was the best $17 I ever spent ;-)
