FM Broadcast Radio Transmitters
functionality to its HD PowerBoost
peak power reduction, providing
inner
carrier
protection.
Some extended hybrid service
modes, including MP11, involve
the use of the total sideband
spectrum in the FM signal. This
has hitherto required broadcasters
to reduce the ERP of their digital
side-bands to avoid adjacent-channel
interference. Nautel first addressed
this issue with the development of
asymmetrical sideband operation,
part of the Nautel HD PowerBoost
technology which began shipping in
2011. HD PowerBoost reduces the
peak-to-average power ratio of the
hybrid FM+IBOC signal. GV Series
transmitters using HD PowerBoost are
claimed to achieve up to 25 per cent
additional digital power and 4 to 8%
better efficiency in -10 dB MP11 mode
tests. No additional license is required
to implement MP11 mode transmission.
Existing GV Series customers can
implement the MP11 mode via a
firmware update.

frequencies simultaneously. Occupying
3U, it captures the full spectrum of
analogue FM (HD is visible but not
captured) on to a 13 terabyte hard
drive. Tools are available via the front
panel touch screen or remotely using
supplied Windows-based software.
Plisch's recently introduced DTR
4902/4904 series FM transmitters
are available in 100 watt to 5 kilowatt
power versions and single drive,
dual drive or N+1 configurations.
Features include auto-calibration at
power-on, 32-bit single-chip digital
signal processing, an embedded RDS
generator and high efficiency (76 per
cent claimed typical efficiency at
98 megahertz. All transmitters
in the series can be operated
via a touchscreen on the front
panel or remotely via IP or
SNMP.

R&S' THR9 series of liquid-cooled
FM transmitters deliver FM output
power of up to 80 kilowatts in
two racks. They are available
in configurations ranging from
single transmitters with a
built-in pump unit and space
for additional system components up
to multi-transmitter systems and N+1
configurations in a single rack. The
THR9 transmitter family for band II
is claimed to offer efficiency values
of up to 75% in analogue FM mode.
The transmitter has fully redundant
cooling and supports IBOC hybrid HD
Radio standard as well as purely digital
standards in band 2.
RVR Elettronica produces a wide
range of FM transmitters, varying in
power from the 30 watt TEX30LCD/S
to the 3.5 kilowatt TEX3500LCD.
Features include stereo encoder,
analogue audio inputs and composite
inputs for SCA/RDS signals. An RDS

encoder with UECP standard functions
is available as an option.
Suono Telecom's ESVA 1K is a 1
kilowatt FM broadcast transmitter in
a 3U chassis weighing 18 kg. Designed
for the 87.5 to 108 MHz frequency
spectrum, it uses five-fan forcedair cooling and can operate across
a temperature range of -10 to +45
Celsius.
Teko Broadcast's Neural is a
series of digital FM stereo exciters/
transmitters available with an output
power from 30 watts to 1.2 megawatts
in a 2U chassis. Also available is
version TX-HE for JPN and OIRT
frequencies. The TX-HE can be used
as standalone transmitter or as driver
feeding high power transmitters and
N+1 systems.
Worldcast Systems' Ecreso FM
5-10kW is a fully digital transmitter
for analogue FM with built-in 1+1
redundancy. It includes hot swappable
power supplies, power amplifiers
and fans, RDS encoding,
digital stereo encoding,
audio
backup
and
a
multiplex
signal
power
limiter.
