Thirteen days ago, it started with this extremely poorly configured raspberry zero with a $8 aliexpress dongle and a $1 antenna. I saw planes and I was happy with my ten planes and 40 messages per second. Mlat worked and I even cut the antenna to lambda/4
Das war einmal - I saw other configurations and made a “fault” and ended up with two FA antennas, two band pass filters and two blue FA sticks. Nerds always have some spare PIs stocked. After a lot of experimenting, the current setup is:
site 57266: FA antenna @12 m, attached on the south side of the roof, line of sight to the north, 5m CLF200 50 Ohm cable connected to a FA pro stick @ Pi3 with Jesie light PiAware, dump1090-muta, collectdd and rdd (Ted Sluis dumptools config)
site 58233: FA antenna @11 m, attached on the south side of the roof, limited line of sight to the north, 1m CLF200 50 Ohm cable connected to a FA pro stick @ Pi3 with Jesie light PiAware, dump1090-fa (seriously: 100 new sites per day?)
The filters affect the stats negatively (slightly), but I have a hack RF one so they might be handy.
But this one sparked the fire:
Reason for having two sites at one location: it allows me to experiment to optimize my configuration. The 1m higher on a 5m cable outperforms the lower @ 1m cable slightly. It could be the setup, but I saw the #positions rise when I switched from dump1090-fa to mutability. There is so much research ahead of me
