you say you just have windowsXP. For a very small price a RTL-SDR
receiver, a suitable antenna and a current microcomputer (eg RPi) would
build you a complete iGate which won't cost much to run, and need an
occasional restart.
Just another experiment....

I'm currently using a RTL-SDR and a Pine64 to watch the ADS-B traffic,
with a collinear antenna built from scrap coax. That's another fun
