Oddity...
I had a wingman in a 172 who has a VERY OLD ANALOG transponder....oddly, it would show and then NOT SHOW on the ADSB, aka "fish finder" in flight. I would have him for a bit, then nothing...
Strangely, he was able to see me almost continuously during the FIVE hours of flight. Thinking through it with other wingmen who had digital transponders, we are thinking the issue was in his non-ADSB equipped ancient analog transponder...what you yinz all think of this problem?
(Yes, yes we all know by now to "look outside" and don't rely on the "fish - finder" -- got that already! This is a question to learn more about the capabilities and limitations of the system of systems)
Thanks for any feedback -

OK, this is me in my plane "seeing" my wingman with the OLDER analog transponder....
OK, and this is him flying off my wing and he is NOT TO BE SEEN on the FISH FINDER! Why not?
OK, this is the COM/NAV setup in his SKYHAWK circa 1977....could this be the ISSUE with me reading his transponder???
