Were you talking to Mark at uAvionix? He seemed pretty straight with me that my best bet wat to try for a 337 with or without field approval and install the skySensor. My gut feel is that the ADSB in market is diminishing and they are not aggressively pursuing certification for the slySensor...
I would also like to have a copy for my '73 Sundowner. I ordered and paid for a SkyLight, but uAvionix is not certifying it and the SkySensor looks like a good alternative.
Thanks
