Currently using the default flarmcfg.txt file, so 7000 and 600.

Here at Chicago Glider Club we have the dubious distinction of
flying right under the approach path into Midway airport. I have
looked at SouthWest planes coming through from all angles, including
head-on. Flying with a C-mode transponder helps a lot, Approach will
guide the big iron around us although I'm sometimes wondering about
the spacing. My PFlarm will indicate through the FlarmView display a
blue dot around my position that is blinking ONLY when a SW or
bigger commercial plane (equipped with TCAS?) is coming through.
Could there be a connection such that the transponder when
interrogated by a TCAS responds in a way that is picked up by
PFlarm? What else might the blue blinking dot mean?
Please enlighten me.

that is a mode C or mode S transponder it is non directional and as
it gets closer the circle should get smaller. Blue means it is above
you.

I've been bench testing 6.06 firmware, and see what I believe Herb is
seeing. A small flashing dot right at current position, but it's short
lived and never gets bigger. It's like the range for mode c/mode s
targets is terrible. I see lots of ADS-B targets at distances greater
than 12 miles, but hardly any mode c/mode s. Maybe they gave up trying
to estimate distance for those targets?
