There is a service bulletin which is a software update for the GTX-327 transponder, dated Aug 2017.
It is software version 2.13. It is apparently for altitude reporting issues when using Gilliam (Grey code) input from an altitude encoder. I have this type input. I am having some problems with my transponder altitude display. It will display 0 altitude a good portion of the time, and what appears to be a correct altitude at other times. I am wondering if this software update will fix my problem. Has any else had this issue, or know anything about this update?
