Thanks Martin, but Red Box is not available in USA; it
does not meet FCC requirements and cannot be sold here.

For USA we have PowerFLARM. Currently PowerFLARM portable
is shipping, with the blind-mounting unit (analog to Red Box)
Real Soon Now (Urs will give a timeline update at the
SSA convention next week). PowerFLARM incorporates transponder
detection (Mode C, Mode S, ADS-B in).

Thanks for the comments,

With the 1.20 update in my box, I drove to the local airport and
observed for about an hour. Local Cessna tookoff and it showed a red
circle that expanded then turned green when it was 1 mile away. Next I
painted an airliner with ADS-B and I got a black arrow showing
position, about 2 miles north and tracking N/E with altitude +9.9
(above 10K). Next another mode C arrival marched down to 1 mile
showing a green circle that turned red as he entered the pattern and
landed. All of these contacts showed their altitude. The only thing I
didn't get was any audio warning, even inside 1/4 mile and zero
altitude difference?
I really like the unit and believe it will give me a reading on most
of the aircraft near my airspace. A majority of the ships flying at my
gliderport have Power flarm and the real threat of hitting another
glider should be greatly reduced. We often run a clearly defined shear-
line in the local mountains and there is lots of head-on traffic as we
all follow the good stuff that is in a narrow band.
See you on my Powerflarm,
JJ
