Nautel Brings Leading Radio
Transmission Technologies
to Forefront

Nautel returns to the NAB show this spring with a suite of
leading transmission technologies for radio broadcasting...

Nautel NX2000 system installed at Antenna Hungaria

O

ver the past several years,
Nautel has emerged as the
leading provider of radio transmission
solutions worldwide and has introduced
several new transmitter lines for MW
and FM applications. The company has
been recognized with multiple industry
awards for innovation in these product
lines, and Nautel was honored in March
2018 with a "Canada's Best Managed
Companies" designation, recognizing
Nautel's stability and growth.
"Nautel has three key strengths
in the broadcast industry," said
John Whyte, Nautel Director of
Marketing. "The first is our reputation
for reliability. Over five decades
of operation, we have produced
some of the industry's most reliable
transmitters. Second is our support,
which is unmatched. Nautel has never
discontinued support on any product,
and our customers greatly appreciate
this. Customers have consistently
ranked Nautel in the highest support
ratings group, comparable to those of
the most successful consumer device
manufacturers in the world. Third
is the strength of our engineering
team, which has been producing some
amazing innovations for broadcasting
and digital transmission."
Nautel now employs one of the
largest technical staffs of any radio
transmitter company in the world.
A leading innovation from Nautel's
technical team is the Advanced
User Interface, which has been
incorporated in all major Nautel
broadcast transmitters since 2008.
Designed to help engineers proactively

manage transmitter monitoring and
service, the AUI takes advantage of
the extensive information available
through the design of Nautel's
modern transmitters. Metering can be
configured down to the level of every
amplifier in the transmitter, and AUI
displays include real-time impedance
measurement,
instrument
grade
spectrum and audio analyzers, IBOC/
DRM modulation analyzers, numerous
control functions, scheduling and
logging. In 2017, Nautel unveiled the
AUI Companion, a mobile app that
brings critical transmitter parameters
directly to the user. Once the software
completes extensive customer testing,
Nautel plans to make the app available
to customers this year.
Engineering Innovations
The company has maintained a
tight focus on digital broadcasting,
announcing updates to its product
lines over the past year which allow
an easy path to digital operation
for broadcast stations of any size.
Both DRM and HD Radio operation
may be accommodated via Nautel
transmitters.
Nautel engineering innovations
also include technologies that could
bring new opportunities to AM and FM
broadcasters. At the 2017 NAB Show,
Nautel Research Engineer Philipp
Schmid demonstrated a concept
for creating a highly reliable SFN
(Single Frequency Network) for HD
Radio transmission. Schmid earned
an award for "Best Paper" at the
2017 NAB BEITC conference for his

presentation on the topic. Schmid's
concept has, to date, been tested in
two mountainous locations in southern
California, with great success in both
instances. Schmid showed that it
was possible to seamlessly hand off
digital signals from one transmitter to
another, with minimal interference, by
utilizing precise modulation and time
synchronization of both the composite
FM audio signal and the IBOC digital
signal.
The 2018 show will feature more
of Schmid's research work and new
test results, this time on Nautel's
innovative HD Multiplex - a concept
that could enable up to 15 HD channels
on one FM frequency.
Nautel has also garnered headlines
for its medium wave products. In 2017,
the company announced completion
of two very large projects. Nautel
successfully deployed the largest
MW Radio transmitter in Europe, a 2
Megawatt station. The Nautel NX2000
system installed at Antenna Hungaria's
site near Solt, Hungary incorporates
five Nautel NX400 transmitters along

with a large, versatile combiner.
Nautel worked closely with Porion
Digital KFT on the installation, which
included building renovations and
air handling modifications as well as
interfacing the NX2000 to Antenna
Hungaria's existing 11 kV voltage
supply. The new transmitter, which
replaced an aging custom-built tube
transmitter, represents significant
power savings, as well as space
savings, for the customer.
Digital Broadcasting
2017 also saw final acceptance
of a four-year project to bring
digital broadcasting to more than
a billion residents of India, with
the commissioning of 27 high
power medium wave transmitters
throughout the country for All India
Radio. AIR's digital broadcasting
system, the largest in the world, uses
high-power (100 - 300 kW) Nautel
MW transmitters, each equipped for
DRM30 transmission, at 27 separate
sites throughout the country. (Nautel
has since shipped another order of
six transmitters to AIR, which will
further expand the reach of their
digital network across 33 sites).
Nautel deployed the transmitters in
association with its in-country partner
Comcon along with Altronic, providing
RF test loads, Digidia, providing DRM
modulators/content
servers
and
Kintronic Labs, supplying matching
systems for the project.
With more than 15,000 transmitters
deployed in 177 countries since 1970
and more than 8,000 deployments
of AUI-enabled transmitters, Nautel
continues to lead the way in providing
valuable new solutions for digital radio
broadcasting and other applications.
