ATC request transponder set at zero
« on: July 20, 2016, 03:19:13 am »
I'm not sure why it only happens to me at KORD, but ATC asks me to set transponder to zero, and it doesn't recognize it when I do switch to all zero. All other airports I'm ask to switch to a four digit transponder code expect for KORD.
