There is a long back story but the short version is that I have the following equipement...

SP-12 MGL GPS
TT22 Trig transponder
TC20 Trig control head

The issue was in getting it to all talk in such a way that ADSB Reports (adsbperformance.faa.gov) would give me a clean report.

Very short answer was the required GPS setting of the TC20 set to "Trig TN72 SIL=3".

-just passing this on in case anyone else happens across the same issue to which seemed no one had the answer.
