Radarspikes from KPDX and KMSP over southern france ?

Hi,
very strange. I never thought that 1GHz can travel so far.
Were flights from the USA.
(or was this a software error?)

There is about 10-15 planes that have transponder errors and are sending out random positions around the world.
If the info says "Radar: KMSP", than the plane was in KMSP area, but transmitted positions in france, south africa, indonesia, russia, pacific ocean and many other random positions.

Hi,
thanks for the answer, but if I am looking at the coordinates I end up somewhere at sea near Oregon or Washington between the US and Japan in the above example. So, the coordinates might be ok and if it had been spotted by KMSP then it must be a spike or whatever ? (minus is west ?)
I clicked on the plane while it was visible over france.

you are right, Mike,
Sometimes the position is shown as 0.something and the it jumps back to the correct position f.ex.-192.
