Darryl,

You said "The TN72 does not meet TSO-C145 requirements (so can't be used for ADS-B Out in experimental aircraft where you want to use it to meet 2020 carriage requirements, in the case of gliders can't be used to meet requirements in the few areas where exemptions don't cover)."

For those of us who cannot keep up, would you kindly list the requirements where the exemptions don't cover?

Many thanks!
-John
