Been playing around with SDR using a RTLSDR dongle, and right now I’m receiving ADS-B from nearby aircraft.

Was shockingly easy to setup using ModeSDeco2 which even provides a local web interface (you would normally feed a site like ADS-B Exchange that combines the results from thousands of receivers around the world).

I’m using a simple dipole antenna stuck to a window with poor LOS to the sky (amazing planning), but I’d like to setup something a little better in the future and maybe feed too. So I thought I’d save some images of my current results to compare with later.
