Note
To run the FAX transmitter in FM+HD or HD only modes, a Harris Broadcast FlexStar or FAX Exciter
and HD Exporter are required. Please refer to the HD Exporter and the Exciter manuals for proper inter-
connection and setup. The HD carriers will not be present until these connections are made and the
interface between this equipment is running properly.
When
the
exciter
is
in
the

mode,
RTAC
samples
are
required
for
the

and
FAX
exciters
to
correct
the
output
signal
properly.
