Ya I'm pretty uncertain now re the take home message for those of us with
mode C installed already. I thought that it was a given that traffic with
TCAS were seeing me and that center/approach could also and vector traffic
around me. After this thread I 'm not feeling froggy about any of this. In
Phoenix and most other places I fly I have been squawking 1200 (Ely,
Moriarty) but are you guys saying that I will be ignored by ground radar due
to filtering for airspeed and by TCAS for 1200???? Glad I spent the $2000.
It all seems inane to me that we go to the effort to be seen and our reward
is being "filtered out" because some moron thinks we aren't a real threat.
