DESCRIPTION
The MASTR III Back-to-Back repeater option allows
two conventional MASTR III Base Stations to be connected
together for simultaneous operation. A typical Remote
Control Base Station system, shown in Figure 1, consists of
one or more control stations, a repeater (two frequencies), a
simplex (one frequency) base station, and mobile and/or
portable units. In the diagram, “R1” is used to indicate a
receiver on frequency F1, “T2” is used to indicate a
transmitter on frequency F2, etc. F3 is the mobile
frequency, F1 is the uplink frequency, and F2 is the
downlink frequency.
RADIO LINK APPLICATION KIT
The Radio Link (Back-to-Back) Application Kit
includes Options SXMK3J and SXZB5K. These kits are
used to modify two standard MASTR III Base Stations for
use as Remote Control (Back-to-Back) Base Stations.
OPTION SXMK3J
The first station (referred to as Station A in this manual)
uses the SXMK3J Radio Link Application Kit. This kit
includes the interconnect harness (19B803976P1) and
F2
In this configuration, when the repeater, Station A,
receives a signal on F1 it re-transmits the signal on F2. It

also routes the signal to the simplex base station, Station B,
which is keyed by R1 to re-transmit the signal on F3. When
Station B receives a signal on F3, it routes the signal to
Station A which is keyed by R3 to re-transmit the signal on
F2. The mobile units can talk to each other on F3.
The linked stations can use the same RF frequency
band/split or different frequency bands/splits.
INSTALLATION
Install the MASTR III Stations using the standard
procedures as directed in LBI-38636. The only exceptions
will be installing the Back-to-Back repeater harness,
verifying correct antenna installation, and programming the
personalities of the two stations.
INTERCONNECTIONS
CIRCUIT ANALYSIS
Reference to signal flow is shown in Figure 2. For
locations of specific connectors and pin-outs refer to the
Interconnection Diagrams at the end of this manual.
When Station A detects a carrier, a carrier with the
proper Channel Guard tone, or a transmit key from a remote
controller, it applies a ground to the Repeat PTT Out
(P2-16). This signal is connected to the Repeat PTT In
(P2-13) of Station B. Filtered Receiver Audio Out (P2-6 &
7) from Station A is connected to the TX Audio In (P2-8 &
9) at the transmitter in Station B. Grounding the Repeat
PTT In keys Station B routing the audio to the transmitter
which re-transmits the signal on F3.
When Station B receives a valid signal, it applies a
ground to the Repeat PTT Out (P2-16). This signal is
connected to the Repeat PTT In (P2-13) of Station A.
Filtered Receiver Audio Out (P2-6 & 7) from Station B is
connected to the TX Audio In (P2-8 & 9) at the transmitter
in Station A. Grounding the Repeat PTT In keys Station A
routing the audio to the transmitter which re-transmits the
signal on F2. The Repeat/Simplex operation is configured
using the PC Programmer, TQ-3353.
Install
the
Back-to-Back
(19B803976P1) as follows:
Harness
1.
Connect the harness connector P201 to the Station
A - T/R Shelf Backplane connector A1P2.
2.

Ensure the operating parameters for channel 1 are
correct with the RF Simplex field set to “NO” and
the Repeat (Rpt) field set to "YES." This enables
the channel to act as a repeater channel.
Select the Control Shelf Options screen and ensure
the Repeater Option is set to "Back-to-Back."
Station B
1.
Select the MASTR III Control Shelf Programming,
Channel Data screen.
2.
Ensure operating parameters for channel 1 are
correct with the RF Simplex field set to “YES” and
the Repeat (Rpt) field set to "NO." This allows the
channel to act as a simplex (one frequency)
channel.
3.
Select the Control Shelf Options screen and ensure
the Repeater Option is set to "Back-to-Back."
Key Priority
The key priority determines which audio signal takes
precedence over the system operation. Stations with
personalities programmed for channel 1 (default) operate
using the Repeat Priority. If the station’s personality is
programmed for channel 2, it will operate using the Link
Priority.
Repeat Priority
When using Channel 1 on Station A the key priority is
as follows:
1
Local Service Mic
2
Remote (DC or Tone)
3
Repeater
4
Link
The audio from station A will take priority over the
audio from station B, for re-transmission by station A.
For Example, (refer to Figure 1) if control station 1
transmits on F1 then a mobile transmits on F3, the audio
signal being re-transmitted by station A on F2 will not
switch from the control station's audio to the mobile's audio,
but will continue to use the audio from the control station.
Link Priority
When using Channel 2 on Station A, the key priority is
as follows:
1
Link
2
Local Service Mic
3
Remote (DC or Tone)
4
Repeater
The audio from station B will take priority over the
audio from station A, for re-transmission by station A.
For Example, (refer to Figure 1) if control station 1
transmits on F1 then a mobile transmits on F3, the audio
signal being re-transmitted by station A on F2 will switch
from the control station's audio to the mobile's audio.
ADJUSTMENT AND TEST
Follow the Station Alignment procedure found in the
MASTR III Installation Manual (LBI-38636). Make final
adjustments using the supplemental instructions described in
Table 1.

LBI-39118
Table 1 - Supplemental Tests and Adjustments
Procedure
Indications and Adjustments
1.
Set both stations for no Compression.
Following the procedures in LBI-38636, set the
Compressor Gain (CP) pot to the preset setting (1023) on
both stations. Set the Compressor Threshold (CT) pot to
32767 on both stations.
2.
Align Line Output (LO) Pot (refer to LBI-38636).
Align the Line Output (LO) pot on both stations according
to the procedures in LBI-38636 except, set the pot for -10
dBm (245mV) output level instead of 0 dBm (775mV).
3.
Apply an "on Channel" RF signal to the receiver of
station A, modulated with a 1000 Hz tone for 3.0 kHz of
FM deviation. Use appropriate Channel Guard (CG)
tone if station has CG, to modulate an additional 750 Hz
of FM deviation.
Station B should transmit.
Measure the FM deviation of Station B, deviation should
be 3.0 kHz ±100 Hz (3.75 kHz ±100 Hz if Station B uses
CG). If necessary, adjust the Station A Line Output (LO)
for the proper deviation as measured at Station B.
If Station A is configured as a repeater, measure the FM
deviation out of the Station A transmitter and verify the
deviation is 3.0 kHz ±100 Hz. (3.75 kHz ±100 Hz if
Station A uses CG).
4.
Remove the RF signal from the receiver of station A.
5.
Apply an "on Channel" RF signal to the receiver of
station B, modulated with a 1000 Hz tone for 3.0 kHz of
FM deviation. Use appropriate Channel Guard (CG)
tone if station has CG, to modulate an additional 750 Hz
of FM deviation.
Station A should transmit.
Measure the FM deviation of Station A. Deviation should
be 3.0 kHz ±100 Hz (3.75 kHz ±100 Hz if Station A uses
CG). If necessary, adjust the Station B Line Output (LO)
for the proper deviation as measured at Station A.
If Station B is configured as a repeater, measure the FM
deviation out of the Station B transmitter and verify that it
is 3.0 kHz dev. (3.75 kHz of deviation if Station B uses
CG).
6.

Remove the RF signal from the receiver of station B.
LBI-39118
If the stations use the same RF transmit and receive
frequencies, Station A will also require installation of the
Antenna relay option, SXSU3A (not included in the Radio
Link Option).
ALTERNATE CONFIGURATIONS
The MASTR III Radio Link Repeater option may also
be installed in one of the following configurations:
•
•
In the Simplex Link configuration shown in Figure 3,
the control station can talk to the mobile units through the
Simplex Link and the mobile units can talk directly to each
other on F2.
Simplex Link - which configures two stations for
simplex operation.
Linked Repeaters - which configures both stations
for repeater operation.
In the Simplex Link configuration shown in Figure 4,
the simplex mobile units (T3/R3) are also able to talk to the
mobile units on the other repeater (T1/R2) which effectively
extends the range of Station A.
Each of these configurations is fully explained in the
following sections of this manual.
SIMPLEX LINK
Programming
In the Simplex Link configuration the two stations
connected together using the 19B803976P1 interconnect
harness. However, both stations are configured for simplex
(single frequency) operation. When Station A receives a
signal on Frequency One (F1), it routes the signal to Station
B which re-transmits the signal on Frequency Two (F2).
When a signal is received by station B on F2, it routes the
signal to Station A which re-transmits the signal on F1. The
conventional stations can use the same RF frequency
band/split or different frequency bands/splits.
Program both stations using TQ-3353 as follows:
T1
T2
R1
R2
F1
A
B
1.
Program the RF Simplex field to "YES," which
automatically sets the Repeat (Rpt) field to “NO.”
2.
Program the Repeater Option for "Back-to-Back."

LINKED REPEATERS
In the Linked Repeater configuration, the two stations
are interconnected using the 19B803976P1 harness. Both
stations are configured for repeater (two frequency)
operation. When Repeater A receives a signal on F1, it
re-transmits the signal on F2. It also routes the audio to
Repeater B which re-transmits the signal on F4. When
Repeater B receives a signal on F3, it re-transmits the signal
on F4. It also routes the audio to Repeater A, which
re-transmits the signal on F2. The conventional stations can
use the same RF frequency band/split or different frequency
bands/splits.
In the Linked Repeater configuration shown in Figure 5,
the control station can talk simultaneously to the mobile
units (F1/F2) through the (R1/T2) repeater and the mobile
units (F3/F4) through the (R3/T4) linked repeater. On the
other side of the link, the mobile units (F3/F4) can talk to
each other through the (R3/T4) repeater and to the control
station and mobile units (F1/F2) through the (R1/T2) linked
repeater at the same time.
Programming
Program both stations using TQ-3353 as follows:
1.
Program the Repeat (Rpt) field to "YES," which
automatically sets the RF Simplex field to “NO.”
F2

Program the Repeater Option for "Back-to-Back."
Key Priority
The key priority determines which audio signal takes
precedence over the system operation. Stations with
personalities programmed for channel 1 (default) operate
using the Repeat Priority. If the station’s personality is
programmed for channel 2, it will operate using the Link
Priority.
Station A - Repeat Priority
When using Channel 1 on Station A the key priority is
as follows:
1
Local Service Mic
2
Remote (DC or Tone)
3
Repeater
4
Link
The audio from Station A will take priority over the
audio from Station B, for re-transmission by Station A.
For Example, if the control station transmits on F1 then
a mobile transmits on F3, the audio signal being retransmitted by Station A will continue to be the audio from
the control station.
