First of all, the person who suggested that digital subcarriers
might prevent persons from "taking over" STL's and uplinks is correct--
they could stop people from actually transmitting their material through
the main broadcast facilities.  However, such systems would not
prevent jammers from simply disrupting communications by interfering
with or capturing out the feed channels, even if they couldn't get
their material "on the air" in a "big" way.

Locating illicit uplinks would indeed be tricky.  I suspect that if
the broadcasters went to DoD and pointed out that what happened to
them could happen to portions of telephone service, etc., DoD might
be forced by public opinion to help in the search.  Another possibility
is that the broadcasters might get together and launch their OWN
low orbit "tracker" satellite just to deal with such situations
when they pop up.

My guess is that the current problems aren't intentional jamming, but
are rather inept ground crews: "Oh, gee, you said one three FIVE degrees;
sorry about that!"  But this doesn't mean that the real jamming won't
come along eventually.
