Introduction
The VRX1000 is a simplex radio coverage extender, which is interfaced to a compatible
remote mount Motorola Solutions Mobile Radio (see Table 1) and enables Portable
Subscriber Units (PSUs) to be used in areas where only Mobile Subscriber Unit (MSU)
coverage is available and PSU coverage is either intermittent or completely absent.
Installed in the trunk of a car, fire truck, armored vehicle, ambulance, the VRX1000
extends radio communications to the PSU users who are outside of the vehicle, inside a
nearby building or in any marginal portable radio coverage areas. The VRX1000 extends
voice (analog, P25 clear or P25 encrypted) communications and supports key trunking
system features. The VRX1000 can be configured to provide various advanced options to
the users.
Unlike the Digital Vehicular Repeater System (DVRS), which can be configured for either
simplex or full duplex operation, the VRX1000 supports only simplex mode and can’t
extend local PSU-to-PSU communications. When using the VRX1000, the Local PSUs
communicate with each other in Talk Around (TA) mode and with the System users via
the VRX1000.
The DVRS is required in applications where local radio coverage extension is needed
(between the Local PSUs) in addition to the System-to-Local PSU and Local PSU-to-
System coverage extension.
This document only describes the VRX1000 operation.
Firmware
The VRX1000 Operation described in this Document requires the following
Firmware:
APX2500/APX4500/APX6500/APX7500/APX8500- firmware release: Host R20.02.00 or
later
APX Mobile Radios operating as the host mobile for the VRX1000 require subscriber
option GA00631 for operation.
APX2000/APX4000/APX6000/APX7000/APX8000 –firmware release R20.02.00 or later.
APX Portable Radios operating through a DVR/VRX1000, utilizing the DVR/VRX1000

VRX1000 Models
Frequency Band of Operation
Depending on the frequency band of operation of the APX Mobile Subscriber Unit (MSU)
and VRX1000, the VRX1000 models are classified as follows:
•In-Band –when the MSU and VRX1000 operate in the same frequency band.
•Cross-Band –when the MSU and VRX1000 operate in two different frequency
bands.
Cross-Band
Cross-Band VRX1000 models do not include any filters on the MSU side since the MSU
and VRX1000 are not intended to simultaneously operate in the same frequency band. In
single band MSU configurations the MSU and VRX1000 operate in different frequency
bands.
In dual band MSU configuration either the MSU & VRX1000 operate in 3 different
frequency bands or one of the MSU frequency bands is locked out when VRX operation
is enabled as shown on Figure 1.
Figure 1 Cross-Band VRX1000 - Conceptual Diagram

8K087X02 R13
VRX1000 Functional Description
January 2020
Page 12 of 74
In-Band
The in-band VRX1000 models are equipped withtwo sets of filters, which are required in
order to ensure interference-free operation when both the MSU and VRX1000 are
transmitting and receiving simultaneously inthe same frequency band. The VRX1000 filter
provides 40 dB isolation on the Mobile radio transmit / receive frequencies. The filter
installed at the output of the MSU is designed to provide 40dB isolation on the VRX1000
TX/RX Frequency Range.
IMPORTANT!
The above filter isolation must be complemented by 30dB minimum antenna
isolation (between the VRX1000 and Mobile Radio antennas) in order to ensure
interference-free operation. It is recommended that the MSU in-band antenna is
mounted on the roof top of the vehicle while the VRX antenna is mounted on the
trunk. Each VRX1000 is shipped equipped with custom filters tuned to the specified
frequency bands –note the frequency range specified on the filter labels.
Programming the VRX / MSU radio to operate on frequencies outside of the original
specified bands may result in intermittent or complete loss of communications.
Frequency changes may require filter retuning or replacement.
NOTE:
The VRX1000 and MSU require two or three (in the case of dual band MSU) separate
antennas.
NOTE:
The In-Band filters connected to the APX MSU are rated for maximum 50 Watts Tx power
and have typical insertion loss of 1.5dB.
Figure 2 In-Band VRX1000 - Conceptual Diagram

VRX1000 Functional Description

Page 13 of 74
Band Locking
Two in-band sets of filters –one placed at the MSU Antenna port and another placed at
the VRX1000 Antenna port are required when both the MSU and VRX1000 are configured
to operate in the same frequency band. Thefrequency specific in-band filters are required
in order to prevent interference when the VRX1000 is receiving & MSU is transmitting and
vice versa.
When the in-band filter is not present, the Band Lock feature must be enabled (by using
the Tweaker programming software) in order to prevent VRX1000 operation on MSU
channels that are explicitly using the same frequency band as the VRX1000. On MSU
channels where the frequency band is not explicitly known such as in multi-site trunking
systems, the MSU will be prevented from using frequencies in the same band while the
VRX1000 is active (i.e. in SYSTEM or LOCAL mode). In this case the MSU will no longer
allow roaming to sites using the locked out band. If the MSU is currently on a trunking site
that uses the locked out band, the MSU will roam to another site. If no other sites are
available, the MSU will enter Out Of Range state. When the VRX1000 is inactive (OFF
mode), the MSU frequency band is unlocked.
Inthe case of a single band MSU (suchas the APX4500 and APX6500), in-band VRX1000
applications always require in-band filters and the Band Locking feature must be disabled.
For MSU conventional channels where the band is known and fixed, the VRX1000 restricts
access to channels using the locked out frequency band.
If Band locking is enabled in the VRX1000 and SCAN is enabled in the MSU, the MSU
will skip over any channels in the scan list that are configured to operate in the same
frequency band as the VRX1000.
IMPORTANT!
A 700MHz VRX1000 interfaced to an APX MSU operating on 800MHz as well as an
800MHz VRX1000 interfaced to an APX MSU operating on 700MHz are considered
In-Band applications and either In-Band filters must be provided or band locking
must be enabled (if the MSU is dual band and VRX operation can be supported on
the non 700/800MHz band).
The above is also valid for any of the UHF Bands –if the MSU operates on any of
the UHF ranges, an UHF VRX interfaced to it will require in-band filters to be
installed or band locking to be enabled.

VRX1000 Operation and Basic Features
The operation of the VRX1000 is determined by the following:
•Firmware, Tier Options and programming settings of the VRX1000 (VRX1000
personality).
•Firmware options and programming settings of the MSU that is interfaced to the
VRX1000.
•Configuration capabilities and programmed settings of the radio system.
•Type and programming settings of the portable radios used for communications
through the VRX1000.
IMPORTANT!
Depending on the selected personality settings and configuration capabilities of the
complete radio system infrastructure, the features / options described throughout
this document may or may not be applicable to the specific VRX1000 operation.
VRX1000 Status Display
The VRX1000 Status is displayed on the MSU Control Head. The VRX1000 current mode
and channel alias are displayed on the top line (for example VR SYS CHAN1) and a
dedicated icon indicates if a VRX1000 is transmitting, receiving, is a Primary or a Non-
Primary etc.
‘DVRS/VRX Enabled’ Mobile Radio TGs / Channels
VRX1000 operation may be enabled (by the VRX1000 and MSU programming) on
selected mobile radio Talk Groups / channels and disabled on others.
Whenthe user selects a DVRS/ VRX1000 Enabled TG / channel onthe MSU control head,
the VRX1000 operation is enabled in the following manner:
•The VRX1000 automatically enters the pre-programmed VRX1000 mode/channel
associated (‘Strapped’) with the selected MSU TG / channel if VRX1000 strapping
is programmed in the VRX1000.
OR
•The user may change the VRX1000 mode / channel (if ‘strapping’ is not enabled)
by pressing the assigned DVRS/VRX1000 button and entering the ‘DVR/
VRX1000 control mode’.
•The VRX1000 can be activated and used to repeat messages betweenthe system
users of the TG/channel selected on the MSU and the PSU users onthe selected
VRX1000 channel.
•If enabled in the VRX1000 personality, ‘VRX1000 Enabled’ tones will be heard
every fewseconds (5-255 sec. programmable) in the MSU speaker, regardless of
the Primary / Secondary status.

‘DVRS/ VRX Disabled’ Mobile Radio TGs / Channels
VRX1000 operation may be enabled on selected mobile radio TalkGroups / channels and
disabled on others.
When the user selects a “DVRS/VRX1000 Disabled” TG / channel on the control head:
•Pressing the DVRS/VRX1000 button results in a VRX1000 Invalid Option Tone
(single low-pitched tone).
•VRX1000 operationis prohibited i.e. all VRX1000 functions are disabled.
•Call Alert Page from the local PSU, sent on the last used VRX1000 channel, can
steer the MSU to a ‘VR Enabled’ mode if programmed accordingly.
Activating the VRX1000 via the MSU Control Head
The VRX1000 mode of operation and status can be changed from the ‘DVRS’ button as
programmed in the APX MSU. The VRX1000 channel can be controlled by pressing the
‘DVRS’button and subsequently pressing the up / down navigation keys to scroll through
the available channel selection.
Automatic VR Activation (AVRA)
The VRX1000 can be activated automatically (switched from OFF or LOCAL to SYSTEM
Mode) if one of the VIP inputs on the MSU control head is wired to the desired trigger
source –portable charger switch or door switch or custom manual switch. When AVRA
is enabled inthe VRX1000, the user still has the optionof manually changing the VRX1000
mode from the MSU Control Head or remotely.
IMPORTANT!
The VRX1000 can be activated via AVRA only if a ‘DVR/VRX Enabled’ TG / Channel
is selected on the MSU.

Remote Activation of the VRX1000
Via Call Alert (Page) to VRX1000
NOTE:
This feature requires the use of a P25 PSU and implies Digitalor Forced Analog VRX1000
Mode of operation.
To remotely activate a VRX1000, the PSU user can send a Call Alert (Page) with the ID
of the specific VRX1000.
Uponreceipt of a Call Alert (Page) from the PSU the VRX1000 will:
•Switch from OFF or LOCAL mode to SYSTEM mode (unless it is already in the
SYSTEM mode). If the selected VRX1000 / MSU channel is programmed as
LOCAL only, the VRX1000 will switch from OFF to LOCAL mode.
•Switch to Primary status and force any other Primary VRX1000 to become a
Secondary unless there is a Permanent Primary (on the same VRX1000 channel)
already present in the same area.
•Force the MSU to revert to a TG selected on the PSU (if programmed).
Via PSU Emergency Alarm
The VRX1000 switches from OFF to SYSTEM mode after a programmable number of
Emergency Alarm attempts sent by a PSU are successfully received by the VRX1000 and
are not serviced by another (Primary) VRX1000.
Via PSU DTMF Tones
To remotely activate a VRX1000 (analog mode), the PSU user can send a
preprogrammed DTMF sequence, which can be received by VRX1000 in the PSU radio
coverage area.
Uponreceipt of the preprogrammed DTMF sequence from the PSU the VRX1000 will:
•Switch from OFF or LOCAL mode to SYSTEM mode.
•Switch to Primary status unless there is already a Primary / Permanent Primary
VRX1000 (onthe same VRX1000 channel) already present in the same area.
DTMF activation is supported on analog or mixed mode VRX1000 channels only.

Via System / Dispatcher Call Alert Page to MSU
Dispatcher can send a Call Alert (Page) to a specific MSU ID, which in turn causes
VRX1000 mode change in the following order: OFF-SYS-LOC-OFF.
The MSU can be programmed to support one of the following configurations:
a. Call Alert / Remote Activation Disabled –the MSU does not respond to any Call
Alert requests
b. CallAlert Enabled –the MSU responds to Call Alerts addressed to its ID and does
NOT initiate VRX1000 mode change
c. Remote Activation Enabled –the MSU will acknowledge Call Alerts addressed to
its ID and will initiate VRX1000 mode change provided the source ID of the Call
Alert is programmed in the “VRX1000 Remote Activation IDs” table.
If “Generate Status on DVR Mode Change” is enabled for a given VRX1000 Profile (in the
APX MSU) , the MSU will send back a mode change status to indicate the current
VRX1000 mode (OFF, SYSTEM, LOCAL). Only the dispatcher console caninterpret those
status messages:
DVR MODE
STATUS VALUE
OFF
1
LOCAL
2
SYSTEM
3
Dispatcher can’t force a Non-Primary VRX1000 to become a Primary and can’t activate a
VRX1000 when a ‘VR Disabled’ mode is selected on the control head.
VRX1000 Modes of Operation
When a “DVRS/VRX Enabled”TG / Channel is selected onthe control head, the VRX1000
can be switched to one of the following modes –OFF, LOCAL or SYSTEM.
OFF mode is used when the VRX1000 repeat is not required (for example while the PSU
user is in the vehicle driving).
LOCAL mode is used when the MSU operator in the car wants to talk only to the Local
PSUs and communications with the FNE are not required (in case of tactical operations
for instance).
SYSTEM mode enables VRX100 repeat of system calls to the local PSUs and vice versa.
The System Calls are heard on the MSU speaker. The local PSU calls are also heard on
the MSU speaker if In Car Monitor is enabled. If the MSU User keys up the MSU
microphone, the call is only repeated by the MSU to the System. The VRX1000 does not
key up.
