Revolutionizing VHF TV
technology
Designed for on -air removal and

modules are identical and fully
interchangeable.
Multiple power supplies ensure
highest on -air reliability. High efficiency
means less heat to manage and lower
operating costs. Compact, roll-out design
integral to each cabinet for service
accessibility.
Parallel power amplifier cabinets
further enhance on -air reliability.
Separate AC feeds for each cabinet
provide a degree of serviceability
never possible with conventional
single tube final amplifiers.
Separate fans provide cooling for
each cabinet.
A state -of- the-art visual /aural
exciter, designed specifically for the
transmitter, provides exceptional
visual performance, and audio performance comparable to that in a top
FM exciter.
PA modules designed for very
high MTBF.
A display screen provides both bar
graph and digital readout of power,
VSWR, voltage and current parameters, plus other data.
Simple, straightforward control of
transmitter on /off, remote /local control and power raise /lower functions is
provided by front -panel pushbuttons.
Status indicators provide a simple
means to observe the condition of all
overload and interlock circuits.
The main control logic circuit provides a central point for control and
monitoring of the entire transmitter.

performance.
Rugged, straightforward construction with less complicated circuitry for
top on -air reliability.
The visual and aural exciters are in
independent, slide -out drawers and

The MCP -2V visual exciter uses
Harris' VIDEO* SAW filter for vestigial

The ultra- linear driver stage
minimizes the amount of correction

On The
Air with Harris
Since its founding in 1922, Harris Corporation's

a digital, solid -state AM transmitter in 1987,
Harris has pioneered over 50 technology and
service innovations. A rich tradition of providing
cutting -edge products and services to broadcasters distinguishes Harris from its competitors.
The Harris difference begins with commitment.
Harris Broadcast Division has the largest investment in plants and equipment of any U.S.
broadcast equipment manufacturer. But the
Harris investment goes far beyond its facilities.
Committed to keeping broadcasters on the air,
Harris has the largest domestic field sales force
of problem -solving radio and television

an

sponsors the industry's only Broadcast Technology Training Center at its Quincy, Illinois, headquarters. Offering regularly scheduled programs
on major Harris broadcast equipment, a two
year degreed college program in broadcast technology, and annual training for foreign broadcasters through the U.S. Telecommunications
