A lot of vintage aircraft have limited or no electric supply and hence don’t operate a transponder. Some have been retrofitted though and you’ll pick them up via MLAT. There are an abundance of portable battery powered ADS-B transmitters entering the market so the proportion of aircraft capable of electronic emission should hopefully increase.Can anyone recommened a decent dump1090 amd x64 docker images? I'm going to give this one a try - https://github.com/jeanralphaviles/dump1090-docker but if there are better ones out there please let me know.
Long term plan is to get a raspberry pi into the loft which should have a great view. I'm near shuttleworth in Bedfordshire, I hope to get some classic planes assuming they fit transponders to those things?
