Telex's BTR-1 Intercomm system forms
the backbone of the NFL and NCAA's
wireless systems that allow a referee to
make announcements. These systems
must work in one of the most complex
RF environments, the
Super Bowl, as
well as college bowl games
.

Here are photos of several NFL coaches
with Telex gear. The headsets are also
from Telex, but Motorola paid for their
logo to be on the earpiece.
