Do not do any of this on the ADSBx images downloads provided here. It is already done. If you're feeding FA with a PI, just use this image. Save your old SD card. Use a new card just in case something goes wrong. You can set your FA UUID hash so you don't have to reclaim the feeder and it will have MLAT and data being sent to ADSBx and FA. https://www.adsbexchange.com/forum/threads/new-piaware-3-5-3-image.618956/ Or you can do this on your FA image. https://github.com/adsbxchange/adsb-exchange That way you'll have all the maintenance scripts and the MLAT client setup.
