I set my location quite precisely using the gear/configure tool a week ago or so and I am confident that when I did this the first time, the dump1090-fa page overlayed a black dot on the map accurately.
That said, the black dot is now some significant distance off (let’s say a km or so).
I plugged the “Location” coordinates which were listed on my userpage into Google maps and they were perfectly accurate. Next I “re-pointed” to my antenna location in the Config tool but still the overlay is off.
Any ideas? Thank you.
