I was using SeeYou to compare flights recorded with my Volkslogger
with those from my PowerFLARM core, to see if there were any
discrepancies. The position recordings overlay very nicely.

But some of the flight traces from the PowerFLARM core (v3.0
firmware)have little blue circles on them. These blue circles are
definitely not marking places where I got FLARM collision warnings
(these don't seem to be plotted at all). Sometimes there's just one
circle, but mostly there are two or three. Their spacing varies from
2 up to 10 seconds.

Does anyone know what these circles are depicting?

I see those, and I wonder if they are Pilot Event (PEV) marks, because
they look like what I remember getting with my 302 when I had a PEV
button connected. I ocasionally press and hold the button on the display
for my Core when I'm trying to access the menu. I wonder if that is
produces a "Pilot Event"?
