Receiver has been running for two years, recently I replaced the dongle and decided to turn on MLAT. In the config file I have changed MLAT to yes after removing the #. Updated my location as I had moved for longitude and Latitude N is 39.06470 and W is -78.09740 . Did a save and returned the Micro SD card to the Raspberry Pi. Site tells me MLAT receiver location not configured. PiAware and Flight Aware show green.
Any suggestions as to what I missed or did wrong?
I’m not sure where you updated the location, but the location is not configured on the sdcard. You need to update the location via your stats page (https://flightaware.com/adsb/stats/user/ag4so, click on the white-on-grey gear, select edit location).
Currently, that site does not have a location manually configured, which is why mlat is disabled:
Thanks for the information I have been trying to enter the coordinates for a while tonight as you instructed however I have a problem. First I went to google maps and found the location my radio was giving is way off so scratch that and went to Google Earth to pinpoint my location. I entered the new coordinates 39.0647 and -78.0975. I save and recheck it looks on until I restart the Pi I recheck and the numbers are changed each time to a different location. for example the last one was 39.97676 -77.85162. Of course MLAT is not accepting I also entered my antenna height using the height from Google Earth plus 10’. Any idea what I am doing wrong?
Give it some time. The clock issue is the clock inside the USB dongle. There is a clock inside that is used for MLAT.
Your neighbours don’t have a lot of MLAT aircraft. I suspect that you should have some by the end of the day.
