I read through a number of the other MLAT discussions and started looking through the mlat.tcl code to see if I can find why its not starting but i’m drawing nothing. I’m sure I am overlooking something very simple. I also looked and see many other piawares around me that have MLAT active.
Definitely ran updates on everything first to rule that out.
I also set my location and elevation a few days ago. Did I do that wrong somehow? Seemed pretty straight forward, I have my Lat, long, and elevation above sea all manually entered through the advanced settings.
According to my site, there are quite a few MLAT (18) sites within 8 miles of me.
Note that I’m running my own instance of dump1090, but it’s the latest mutability release (specifically, this commit github.com/mutability/dump1090/ … ee6aa74bef) . In my case, dump1090 isn’t running on this machine (a linux VPS) but on an OpenWrt device in my house; I have tunnels set up on 30001, 30002, 30003, 30004, and 30005 between the VPS and the OpenWrt device.
On startup, /tmp/piaware.out looks like this:

Is this a legitimate scenario? Can I run piaware this way and expect to get mlat data? Or is the problem simply that there aren’t enough people in my area for MLAT to work?
Minimum 4 piaware receivers that can see the same aircraft. Last time I checked that area, part of the problem was that some of the sites had poor range. That area is also near the overlap of several server regions and the north Africa side actually has so few receivers that there’s not even a server running there. I’ll look at whether the server balancing needs to be rerun around there.
Thanks obj! Right now my range is pretty poor, but I can see that there are a few sites nearby with some excellent range. I’ve been approved for a flightfeeder; hopefully when that arrives (and more importantly, its proper antenna!), I should be getting much better range. I’m not LOS to LLBG, but I am LOS to above 300 feet AGL at LLBG
