Description
1. DESCRIPTION
Nucomm’s NewsCaster VT2 series is a two
box Digital and Analog ENG/OB Microwave
Transmitter System. The Mast Mounted
Microwave Transmitter is designed to operate
in any specified band in the 1.00 to 15.5 GHz
frequency range. Each unit is field
programmable and configurable to meet a
wide range of customer requirements.
The NewsCaster VT2 is a “split-box”
transmitter system utilizing a rack-mounted
Control Unit (19” x 1RU, sometimes referred
to as the “IDU”), and a Mast Mounted
transmitter RF Head (or “ODU”). The two are
connected with a single IF cable (RG-6 coax,
or optional Triax), which carries the 70 MHz
IF, Control Data, and DC power. For cases
where an existing IF cable in the Nycoil must
be used, and cannot support the diplexing of
the DC power, the NewsCaster VT2 can be
fitted with an AUX Power output to send the
power via separate conductors. (Refer to
Table 8.)
The NewsCaster VT2 is fully integrated with
an Analog FM modulator, compliant superlow delay MPEG 2 Encoder and Multimode
Digital Modulator. Available modulations
include FM (NTSC / PAL), COFDM, optional
single carrier QAM, and optional VSB. As
additional digital modulation formats become
available, the VT2 can easily be software
updated. This makes the VT2 extremely
flexible while greatly reducing circuit
complexity.
M17-0002-00A Rev 4

Figure 1: NewsCaster VT2 System Diagram
Highlighted features include six “Quick-Key”
presets that allow single button operation,
integrated dynamic color bars, and HD
transport capability. Also, special menus have
been included to ease the BAS relocation
process.
Other available options for the NewsCaster
VT2 include Pan & Tilt control, a 10Watt
Digital High Power Amplifier, remote control
and monitoring functionality, multi-band
operation, etc.
This manual is written in a general form to
cover all configurations and options for the
NewsCaster VT2 within the 1.00 to
15.5 GHz frequency range.
The convention of this manual is to show nonstandard configuration options with shaded
text, as shown here.

Digital & Analog Input Signals:
The NEWSCASTER VT2 Control Unit
accepts multiple input formats. These include:
• Composite video (NTSC & PAL).
• Digital video as SDI, with audio deembedding.
• ASI.
• Two analog audio (optionally four).
• One digital AES/EBU audio
(optionally four).
• 70 MHz.
The audio’s can be combined with the video
via the MPEG-2 encoder or the FM subcarriers. A key feature of the Newscaster VT2
is that the SDI video can be converted
internally to composite video and transmitted
as FM analog modulation. The Audio and
Video signal flow is shown in Figure 3.
In Digital mode, the NewsCaster VT2 accepts
video as SDI, ASI, or Composite, along with
LINE, Embedded, or AES audio(s), and
digitally compresses the signals using 4:2:2 or
4:2:0 MPEG2 encoding. The encoded signal
is then internally modulated with one of the
user-selected formats: COFDM, or optional
QAM or VSB. (Refer to Figure 3).
For additional flexibility, an ASI Out port is
provided, enabling the NewsCaster VT2 to be
used as a standalone ASI Encoder

Features
In Analog mode, the NewsCaster VT2 accepts
SDI or Composite video, and LINE,
Embedded, or AES audio.
The NewsCaster VT2 can also accept
externally modulated signals via the 70 MHz
Input Port.
Audio Sub-carriers:
The two standard, or four optional,
synthesized audio sub-carriers are field
programmable and feature individual source
selection (OFF / LINE / TONE / AES) and
gain control via the menu system or audio
“Quick-Key”. The sub-carrier frequencies,
mode, and additional gain are front panel
adjustable using the menu system.
Prime Power:
The standard Control Unit input voltage is 90
to 240 volts AC (40 to 60 Hz). Optionally, the
system can be configured for DC ranging from
+11 to +32 VDC, or for both AC & DC
operation in the ranges listed above. In all
configurations, the system automatically
adapts to the input voltage without requiring
the user to change any jumpers, switches or
settings. Appropriate line cords are provided.
Standby Mode:
The Standby Mode is accessed from the front
panel under the grouping labeled “MODE”.
There are three options or functions that can
be selected: “Normal”, STANDBY” and
V.PRES.STBY”. In the “NORMAL” mode,
the NewsCaster VT2 amplifiers are powered
and transmitting. In the “STANDBY” mode,
the transmitter is powered on, but the RF
output is muted, enabling the transmitter to be
tuned safely without radiating off-frequency
emissions. The NewsCaster VT2 will remain
in “STANDBY” until on-frequency lock has
been obtained. Switching from “STANDBY”
to the “NORMAL” (operating) mode results
in instantaneous on-frequency transmission.
M17-0002-00A Rev 4
15
If the synthesizer has not attained lock when
the Standby switch is switched to
“NORMAL”, the unit will remain in
STANDBY” until on-frequency lock has been
obtained.
When the transmitter is in the Analog mode
there is an additional “STANDBY” mode
called “V.Pres. Sdtby” (Video Presence
Remote). When in this mode, the transmitter
will be in the “Normal” transmitting mode as
long as the video source is connected to the
Video or SDI input. When the video is
removed, the transmitter will go to
“STANDBY” in five seconds. Reapplying the
video will immediately turn the transmitter
back ON. The Video Presence Remote
Standby mode enables the camera operator to
remotely place the transmitter in standby or
turn it ON.
Dynamic Color Bar Generator:
To activate the Dynamic Color Bar Generator,
press the “TEST COL” button on the front
panel of the Control Unit. The LED above the
button will light. The color bar pattern is the
SMPTE color bar standard. In the middle of
the pattern is a 16 character ID that can be
programmed through the LCD display. The
first character in the ID will blink to indicate
that the microwave link is active. In a digital
system if the decoder stops decoding, the
picture will freeze and the operator would
have know way of knowing this. By causing
one of the ID characters to blink, one can
quickly tell that the link is operating properly.
In addition to numbers and characters, several
symbols are available for display in the ID.
These symbols include a helicopter, a Van, a
camera, etc.
When the Dynamic Color Bar Generator is
activated, a 1 kHz test tone is inputted to the
active audio channels. The left channel will be
a CW tone. The right channel will be a pulsed
tone.

Preset Keys:
Nucomm has designed six Preset Keys into
the front panel of the Newscaster VT2. These
keys are used to instantly recall previously
programmed configuration parameters such as
frequency, modulation format, analog or
digital, video and audio input type, etc. To
program a Preset Key, first set the Newscaster
VT2 to the desired operating configuration.
Then hold one of the six Preset Keys in until a
confirmation message is displayed (roughly 10
seconds).
To recall the Preset, simply press appropriate
key. The display will indicate the Newscaster
VT2 has been re-configured per the Preset.
Frequency Coverage:
Nucomm’s NewsCaster VT2 transmitters are
available in single-, dual-, and tri-band
configurations. This manual covers all the
models in the NewsCaster VT2 series.
typical system, the power to the RF Head,
which is diplexed onto the center conductor of
the cable for coax, or through the inner shield
when Triax is used. The cable conductor must
carry 2 to 3 amps of current at +48 volts. .The
center conductor of Belden 1694A/RG 6U
coax (or equivalent), and the inner shield of
the Belden 8232A/RG59U triax are large
enough to carry this current with a minimum
of voltage drop.
When using video cable such as RG 58, or
Belden 1505/RG-59U, the voltage drop
through the center conductor is too great to
carry the diplexed +48volts. To support the
use of these cables which may be existing in
the Nycoil and must be used, Nucomm has
provided an auxiliary power (“AUX Power”)
connector that routes the power to external
wires. Refer to Section 4.7 for details.
The NewsCaster VT2 series radios provide full
coverage of the 2, 7 & 13GHz US frequency
bands, and/or other bands as required
internationally, from 1 to 15.5 GHz. The US
frequency bands are given in Table 1 through
Table 5. Band and channel selections are
made and clearly displayed via the front panel
LCD interface.
The standard coax cable required between the
Control Unit and the RF Head must have an
impedance of 75 Ohms. The Newscaster will
on occasion, be used to replace systems that
use 50 Ohm RF or video type coax cable in an
existing Nycoil. On special request, Nucomm
can configure the Newscaster VT2 system to
operate using these 50 Ohm cables. Again,
depending on the type of coax cable used in
the pre-existing Nycoil, the power to the RF
Head may require the use of the AUX Power
option.
Antenna Operation:
RF Head Features:
The Newscaster VT2 can control a number of
antenna functions, including:
Polarization switching
Directional-Omni antenna switching
Selection between RWI or NSI Antennas
The rugged NewsCaster VT2 RF Head, as
shown in Figure 4, includes:
• IF to RF Up-Converter
• RF Power Amplifier
• Low Noise Frequency Synthesizer
• Diplexer that splits the +48 volts, the
70 MHz and the Control Data.
• DC to DC Converter
• Optional Pan & Tilt Controller
• Optional Omni/Directional Antenna

Coax Cable Requirements:
The NEWSCASTER VT2 Control Unit and
RF Head are typically connected with a single

available from Nucomm if needed.
DC Power: When configured for DC, the
system can operate on DC power ranging from
+11 to +32 VDC. Connect the provided DC
line cord between the lugs on the back of the
unit to an appropriate DC power source. (–)
for GND, and (+) for the +11 to +32VDC.
The 70 MHz input port allows an externally
modulated signal to be inputted to the system
for RF transmission. To utilize this feature,
“External 70MHz” must be selected as an
input via the front panel interface. Refer to
Section 5 for details.
The 70 MHz output port can be connected to a
spectrum analyzer for monitoring, or to an
external transmitter. (see Figure 6, Detail 2).
Note: When “External 70 MHz” input is
selected, the 70 MHz out is a loopthrough
only.
In all configurations, the system automatically
adapts to the input voltage without requiring
the user to change any jumpers, switches or
settings.
Video
All video inputs/outputs are made via clearly
marked 75 Ω BNC connectors. (Refer to
Figure 6, Detail 3 and Detail 4.) Simply
connect a 75 Ω coaxial cable between the
source and target equipment, and select the
appropriate input type via the front panel
interface. Refer to Section 5 for details.
Available video inputs and outputs are:
• SDI (input)
• ASI IN
• ASI OUT (from the internal encoder)

one Digital audio is available in the standard
“two audio” configuration.
IF Interface and AUX Power
When the IF Cable is suitable, a single TNC
(or optional Triax) connector (Figure 6, Detail
7) is used to output the three signals that must
pass between the Control Unit and the RF
Head:
(a) the modulated 70 MHz signal
(b) the inter-unit control data
(c) the +48VDC for the RF Head.
Figure 8: Control Unit, RS-232 Connector
For cases when an existing non-conforming IF
cable that cannot handle +48VDC must be
used, the AUX Power option must be fitted
and will provide the +48V on a separate
connector (Figure 6, Detail 5) for transport to
the RF Head via dedicated conductors.
Table 7 lists conforming cables and details the
various configurations possible with and
without the AUX Power option.
NOTE: When AUX Power is configured, the
+48v still remains available at the IF
Interface port. This allows the user to
upgrade to a conforming IF cable without
requiring any changes to the unit.
Additional detailed information on the
interconnection between the Control Unit and
RF Head is found in Sections 4.7 through 4.9.
Remote
The remote control port (Figure 6, Detail 8)
allows for full control and monitoring of the
NewsCaster VT2. Both RS232 and RS485 are
supported. Refer to Section 5.3.2 for settings.

INSTALL
Nucomm’s mast mounted transmitter consists
of a single RF head (containing the upconverter, P&T, PSU, Antenna Controls, and
amplifier). There is also a legacy “extended
power output” option which consisted of two
mast mounted units, the RF Head (containing
the up-converter, P&T, PSU and Antenna
Controls) and the High Power Amplifier (or
HPA). The legacy system is no longer
manufactured.
In a typical installation of Nucomm's
NewsCaster VT2, the RF Head (and HPA if
configured) are mounted on the Pan & Tilt
mechanism, which is attached to a pneumatic
To ease the mounting of the RF Head (and
legacy HPA if configured) to the Pan & Tilt,
mounting adapter plates are available. The
plate is first mounted to the Pan & Tilt with
(4) 1/4-20x.750" flat head screws, then the RF
Head (and legacy HPA if configured) are
mounted to the adapter plate(s). For cases
when the mounting adapter plate is not used,
the hole pattern of the RF Head (and legacy
HPA) base plate has been provided (See
Figure 28).
Note: The RF Head(s) should be mounted so
that the heat sink fins are vertical during
operation.
Note: Attach Mounting Plate(s) to Pan & Tilt before attaching to RF Head (and/or legacy High Power Amplifier).

RF HEAD CONNECTORS
IF Interface and AUX Power
The TNC, or Triax, IF connector inputs the
diplexed 70 MHz, inter-unit control data, and
DC power for the RF Head when Belden
1694, or Triax, cable is used. If RG-59 is
used, then DC is input from the Aux Power
cable via the Aux DC Power input. (Refer
also to Figure 21, Detail 11.)
To Pan / Tilt
This connector (if configured) outputs signals
and power for the Pan & Tilt unit. Refer to
Table 12 and Figure 17 for cabling and pinouts. (Refer also to Figure 21, Detail 13.)
RF Output
Antenna Polarization
The RF output is via a Type-N connector
located at the center rear of the NewsCaster
VT2 RF Head and carried, via a 50 Ω low-loss
coaxial cable, to the antenna. Turn the cable
connector clockwise while keeping it in line
with the transmitter connector. To avoid
unnecessary connector wear, do not allow the
cable to rotate while you connect it to the
transmitter. (Refer also to Figure 21,
Detail 15.)
This connector (if configured) receives the
antenna polarity control signals from the
Control Unit. Both NSI and Radio Waves
antennas are compatible, as well as others.
See Table 13 & Figure 18 for NSI details.
See Table 14 & Figure 19 for RWI details.
(Refer also to Figure 21, Detail 12.)
Pan / Tilt Power (from Control)
This connector (if configured) inputs power
from the Control Unit, which is then passed on
to the RF Head.

Composite - The signal applied at the
INPUT connector is routed through the
internal low pass filter to modulate the
output. Typically, this filter has a
bandwidth of about 4.0 MHz for NTSC
and 5.6 MHz for PAL. The NTSC filter
selectivity ensures the higher frequency
video components do not interfere with
the 4.83 MHz audio subcarrier.
SDI - SDI is converted to Composite via
an internal circuit and then processed as
a Composite signal.
External 70 MHz FM - The input
bypasses the modulator, and is routed
directly to the heterodyne up-converter.
When digital modulation is selected, the

NEXTEL BAS RELOCATION SETTINGS
For our US clients, the ChannelMaster is designed so that, when properly configured per the
following guidelines, you will only need to change one setting, on one screen when it’s time to
switch over to the “post-Nextel” 2GHz band plan
To preset the unit to allow a “one setting” switchover, there are two groups of settings that must be
made in advance: “AUDIO SUB-CARRIER FREQUENCY” and “CHANNEL BANDWIDTH &
BAND PLAN”. These are described below.
5.4.1Audio Sub-Carrier Frequency
In this section you set your “pre-Nextel” and “post-Nextel” Audio Sub-Carrier (ASC) frequencies,
so that when you make the switchover they will be ready to go.
Start the ASC set-up procedure by making the following menu selections:
SETTINGS>MODULATOR/ENCODER>ANALOG>AUDIO
Í
This brings up a screen similar to the one at right, with the
settings and selections as described below:
SC1 Insertion: (-20 to -40dBc)
2(17)/7/13: 4.83 MHz
2(12) 1-7: 4.83 MHz
2(12) 8-10: 4.83 MHz
NOTE: Press “Up” & “Down” to scroll through the ASC’s, and press “Left” & “Right” to scroll
through the available settings. The settings for all ASC’s are modified in the same fashion. ASC#1
is used as the example.
2(17)/7/13
This setting controls the frequency for the selected Sub-Carrier when
operating in the “pre-Nextel” 2GHz band (USA), and also for all the other
frequency bands (i.e. 7GHz or 13GHz). The possible range for this setting is
4.83MHz to 8.5MHz.
2(12) 1-7
This setting controls the frequency for the selected Sub-Carrier when
operating in the “post-Nextel” 2GHz band (USA) on channels 1 through 7.
The possible range for this setting is 4.83MHz to 5.8MHz
2(12) 8-10
This setting controls the frequency for the selected Sub-Carrier when
operating in the “post-Nextel” 2GHz band (USA) on channels 8 through 10.
The possible range for this setting is 4.83MHz to 8.5MHz

5.4.2 Channel Bandwidth and Band Plan
In this section you can set your “pre-Nextel” and “post-Nextel” Video Bandwidth Deviation, so
that when you make the switchover they will be ready to go.
Start this set-up procedure by making the following menu selections:
MENU>Settings>Options>Nextel
2GHz Freq Plan: 2G(17), 2G(12)
This brings up the screen at right, with the settings
BW(2G(17)/7/13): 4MHz, 3MHz
and selections as described below:
BW(2G(12)8-10): 4MHz, 3MHz
2GHz Freq Plan
This setting controls the 2GHz Frequency Plan which will be
used by the radio. Select the 17MHz “pre-Nextel” bandplan by
choosing “2G(17)”, or the 12MHz “post-Nextel” bandplan by
choosing “2G(12)”.
BW(2G(17)(7/13)
This setting controls your Video Deviation bandwidth when
operating in the “pre-Nextel” 2GHz band (USA), and also for all
the other frequency bands (i.e. 7GHz or 13GHz). The possible
selections are 3MHz or 4MHz.
BW(2G(12) 8-10)
This setting controls the Video Deviation bandwidth when
operating in the “post-Nextel” 2GHz band (USA) on channels 8
through 10. The possible selections are 3MHz or 4MHz.
NOTE: Due to bandwidth limitations of the “post-Nextel” 2GHz bandplan, in “2G(12)” mode, the
Video Deviation bandwidth of 2GHz channels 1 through 7 is locked at 3MHz..
5.4.3 SWITCHOVER TO “POST-NEXTEL” SETTINGS
For our US clients, when your DMA switchover date arrives, assuming you have already set the unit
per the preceding guidelines, you will only need to take the following steps to put the radio on the
new “post-Nextel” settings:
Step #1:
Navigate to the following menu: Settings>Options>Nextel
Step #2:
Change your “2GHz Freq Plan” setting from “2G(17)” to “2G(12)”
Step #3:
Done!
