Hi All, I took a break for a a couple of months and after the MSFS updates, I have flow 4 times, twice in the TBM and twice in the CJ4, and both IFR flights I get multiple "XXX check transponder" msgs from ATC. After this I started noticing the transponder code chainging on it's own. I don't think it's PF3 that is causing it, and I have a pretty vanilla install of FS2020. Anyone heard of this?
Thanks
