I have worked with the Kobo a bit more and...
The Kobo interferres with the radio far too much, needing maximum squelch to get rid of it. Perhaps the frequency of its screen refresh, or something. Anyway, we need to reduce that somehow.
There IS a web browser on the Kobo, in the Beta Functions section. But there are too many actions to get the Kobo connected. Glider pilots want an on-off switch, and nothing more.
The XC-Soar software does just this. When you turn on the Kobo, it comes up with XC-Soar, and a button to press when you fly. Could not be simpler. The Kobo could be a good PAW screen, if it did something similar, and brought up the ‘radar’ screen.
The XC-Soar software does link to PAW (eventually). However, it will not exclude high-and-distant aircraft, and so we ended up with 70 aircraft on the screen. Would it be possible to filter out the distant and high aircraft, at the PAW end, instead of at the Kobo end? Choices of....
5km, 10km, 20km, 50km.
1000ft, 2000ft, 3000ft.
And only give that data to the Kobo.
