This is very confusing.Â* So a TN72 is not a TSO device, but is compliant
and therefore can be mounted in an experimental aircraft which will be
seen by all compliant ADS-B In systems?Â* I feel cheated by having a
certificated aircraft!

Walt, I think you are misunderstanding what Trig wrote. A TN72 GPS Source will be seen by everybody. That is why anybody doing ADS-B Out in an experimental glider with a TT22 should be equipping with at least a TN72 (or TN70, TN70 required for certified gliders).
