So, dare we ask, why is the FAA deploying ASR11 without mode-s? Two
reasons: someone in the FAA budget office had bad data that indicated
no one was using mode-s or TIS, and lacking user support, they decided
to buy the radars without the mode-s option to save money.

This is after the twisted peoples arms to get Mode S or reamed them to
fix their old Mode A/C transponder so that it would work properly in
the presence of a Mode S interrogation (due to their own stupidity
in not designing the Mode S protocol properly). Now that the FAA
actually has given real incentive for people to want mode S they're
pulling the plug. Typical FAA bull****.
