I have recently assembled an ADS-B reciever with a raspberry pi 2 model B computer. I first started testing it yesterday with one of the first versions of Piaware (v1.2 I think). This morning I upgraded it to one of the latest versions (v2.1) which should include MLAT. On my stats page I enabled MLAT and it says that I am synchronized with 6 nearby recievers. I spent the whole day with my computer and my ADS-B on, I haven’t caught a single aircraft with MLAT yet (no purple planes at all). I have checked with flightradar 24 and there were aircraft flying near my location without ADS-B (only mode S transpoder), it said T-MLAT radar in their descriptions. My antenna is placed indoors (to poor for an outdoor antenna lol, still a student) and clearly recognizes ADS-B equiped aircraft within a 60/120 mile radius. Is this normal or I didn’t configure my software properly ?
Thanks in avance for your help
