As an aside, I remember from my training a LONG time ago that ATC
can use direction finding on your radio signal to give you your
general location. A "DF steer", I think it was called. Is that
still available?

I've heard of it. I suppose if the FAA is throwing away everything
else, they'll want to throw this away, too.

Your "suppose" is useless in the real world.

DF Steers were available only from Flight Service Stations. Since Flight
Service has been contracted out to Lockheed Martin who have centralized the
service and closed down most of the FSS facilities, I would certainly not
depend on DF Steers being available.
