An interesting little problem. Firstly the system; an Odroid XU4, running an Airspy, utilising wiedehopf’s set up option, which includes the running the Flightaware install of piaware and dump 1090 procedure. Piaware ver 3.7.1.
Everything appears to be running ok. 3 green boxes in my site information and apparent recording of the limited MLAT flights showing in collection graph and control panel log showing MLAT signals being used. BUT the site information data in the right column line Multilateration (MLAT) showing supported / enabled but not showing synchronized with ## nearby receivers. I have 2 other units set up, a Radarcape and raspberry 3+, both showing at the same time the number of nearby receivers sync’d etc.
I am not sure what problem is causing the apparent sync’d MLAT system but not showing how many it has sync’d with… ?? Ideas ??
