ADS-B Out

[n85ae]

After a lot of phone calls, I think I know what is needed for ADS-B Out
compliance. I'm personally waiting to see if prices drop. But were a person to
do it today. To go from a "normal" Mode-C Transponder, with a conventional
Encoder ... I created this diagram. Hope it helps make sense out of this mess.
If I got something horribly wrong, I'll fix the diagram.

Both Navworx, and Freeflight are similar, but differ a bit in how they
listen to the transponder output. Navworx listens on the cable to the
transponder antenna, Freeflight samples the RF output.

Thanks!
