RF Exposure Warning
Exposure to radio frequency (RF) energy has been identified as a potential environmental factor that must be
considered before a radio transmitter can be authorized or licensed. The FCC and IC have therefore developed
maximum permissible exposure (MPE) limits for field strength and power density, listed in FCC 47 CFR 1.1310
and IC RSS-102 Issue 2 Sect 4. The FCC has furthermore determined that determination of compliance with
these exposure limits, and preparation of an Environmental Assessment (EA) if the limits are exceeded, is
necessary only for facilities, operations and transmitters that fall into certain risk categories, listed in FCC 47
CFR 1.1307 (b), Table 1. All other facilities, operations and transmitters are categorically excluded from making
such studies or preparing an EA, except as indicated in FCC 47 CFR 1.1307 (c) and (d).
Revised FCC OET Bulletin 65 (Edition 97-01) and IC RSS-102 Issue 2 provide assistance in determining
whether a proposed or existing transmitting facility, operation or device complies with RF exposure limits. In
accordance with OET Bulletin 65, FCC 47 CFR 1.1307 (b) and RSS-102 Issue Sect 2.5, this Daniels Electronics
Ltd. transmitter is categorically excluded from routine evaluation or preparing an EA for RF emissions and this
exclusion is sufficient basis for assuming compliance with FCC/IC MPE limits. This exclusion is subject to the
limits specified in FCC 47 CFR 1.1307 (b), 1.1310 and IC RSS-102 Issue 2 Sect 4. Daniels Electronics Ltd. has
no reason to believe that this excluded transmitter encompasses exceptional characteristics that could cause
non-compliance.
Notes:
• The FCC and IC’s exposure guidelines constitute exposure limits, not emission limits. They are relevant
to locations that are accessible to workers or members of the public. Such access can be restricted or
controlled by appropriate means (i.e., fences, warning signs, etc.).
• The FCC and IC’s limits apply cumulatively to all sources of RF emissions affecting a given site. Sites
exceeding these limits are subject to an EA and must provide test reports indicating compliance.
RF Safety Guidelines and Information
Base and Repeater radio transmitters are designed to generate and radiate RF energy by means of an external
antenna, typically mounted at a significant height above ground to provide adequate signal coverage. To reduce
potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (EIRP) is not more than that permitted for successful communication. The following
antenna installation guidelines are extracted from Appendix A from OET Bulletin 65 and must be adhered to in
order to ensure RF exposure compliance:
Non-building-mounted Antennas:
Height above ground level to lowest point of antenna ≥ 10 m or
Power ≤ 1000 W ERP (1640 W EIRP)
Building-mounted Antennas:
Power ≤ 1000 W ERP (1640 W EIRP)
The following RF Safety Guidelines should be observed when working in or around transmitter sites:
• Do not work on or around any transmitting antenna while RF power is applied.
• Before working on an antenna, disable the appropriate transmitter and ensure a “DO NOT USE” or
similar sign is placed on or near the PTT or key-up control.
• Assume all antennas are active unless specifically indicated otherwise.
• Never operate a transmitter with the cover removed.
• Ensure all personnel entering a transmitter site have electromagnetic energy awareness training.
For more information on RF energy exposure and compliance, please refer to the following:
1. FCC Code of Regulations; 47 CFR 1.1307 and 1.1310.
2. FCC OET Bulletin 65, Edition 97-01, “Evaluating Compliance with FCC Guidelines for
Human Exposure to Radiofrequency Electromagnetic Fields.”

General Information
NOTE: The General Information and the Theory of Operation sections are common for all models of
MT-4E Receivers and Transmitters. Information that is specific to individual models will be
identified where relevant.
I n troduct ion
P25 Digital Mode
The MT-4E Receiver and Transmitter are FM
radio modules capable of analog operation
in 12.5 kHz (narrow band) or 25 kHz (wide
band) channels. A firmware upgrade may be
purchased to allow P25 Digital operation.
Modular design allows each of the receiver and
transmitter’s internal modules to be individually
assembled and tested, which facilitates
construction, tuning and general maintenance.
When the P25 firmware upgrade is purchased,
the MT-4E family of receivers and transmitters
may be configured for P25 Digital operation,
or mixed mode operation. In a repeater
configuration, the receiver passes the complete
P25 Digital voice packet directly to the
transmitter so no P25 Digital information is lost.
The MT-4E Receiver and Transmitter combine
state of the art performance in a compact
modular enclosure for applications ranging from
remote mountain top repeaters to congested
urban radio environments. Each module is
characterized by dependable, low maintenance
performance under the most severe
environmental conditions.
The MT-4E Receiver and Transmitter are
primarily software controlled radio modules,
allowing tuning, programming and maintenance
to be done via software service with few
hardware adjustments required.
All P25 specifications, operational description
and information contained in this instruction
manual require the P25 firmware upgrade to
function. If the MT-4E Receiver and Transmitter
are purchased without the P25 firmware
upgrade, the radio will program and operate in
analog mode only.
NOTE: This equipment is not to be operated
within the frequency band
406–406.1 MHz unless specifically
authorized by the Federal
Communications Commission or Industry
Canada in conjunction with COSPAS /
SARSAT.
The MT-4E series is compatible with all Daniels’
subrack and base station enclosures. It supports
a basic analog interface and may be used in
a mixed system with MT-3 and MT-4 series
receivers and transmitters.

General Information
Secure Communications
The receiver and transmitter are capable of decoding and encoding secure communications if a
DES‑OFB / AES Encryption Module is installed. To successfully decode or encode a transmission,
the encryption module must be programmed with a valid encryption key using the Motorola KVL 3000
Plus Keyloader in conjunction with a Daniels Keyloader Cable. The Daniels Keyloader Cable plugs
into the front panel RJ45 jack on the front of the receiver or transmitter module.
Consult Keyloader instructions for details on loading a key. A loaded key may be zeroized by pulling
the CLEAR KEYS 1, then the CLEAR KEYS 2 inputs to ground 500 ms apart. Alternately, the
CI‑BC‑4E Base Controller or Universal Interface Card (UIC) may be used to clear the keys for all
modules in a system with a single key press of the switch marked ZEROIZE KEY. The CI‑BC‑4E
Base Controller can also be used to control whether the transmitter outputs a secure or a clear signal.
Firmware Upgrades
Receiver and transmitter firmware upgrading is performed with the PC-based firmware flashing
software. A USB Type A to 5-pin Mini-B cable is used to connect the USB port of an IBM-compatible
computer to the USB port on the front panel of the receiver or transmitter module.
Firmware upgrades can be found on the Daniels Electronics Ltd. website at www.danelec.com.

General Information
C ha nnel and Bank Se l ec ti on
Four channel select lines, CSEL 0 – CSEL 3, from the motherboard are brought into the receiver and
transmitter modules by the 48-pin rear connector, allowing selection of 16 different channels. These
signals are normally pulled low in the receiver and transmitter, but are typically set by jumpers on
the motherboard to select Channel 1 by default. In addition, a bank select input is provided to switch
between Bank A and B, each of which has 16 channels. The Bank select line normally floats high
(+5 V), selecting Bank A, but may be pulled low or high externally to select Bank B.
Channel and Bank Select Line Mapping
The table below shows the relationship between the states of the bank and channel select lines. Note
that the channel select lines follow a binary pattern, but that the binary “0” represents Channel 1.
The Bank A/B select line normally floats high (+5 V), selecting Bank A, but may be pulled low or high
externally via the Bank A/B select line.

Radio Service Software Programming
Installation
The RSS should install automatically once the CD is inserted. If not, run SETUP.EXE, located on
the CD.
NOTE: The receiver and transmitter must be programmed separately.
Once the connections are made, the RSS may be run on the computer and the radio switched on.
The first time a receiver or transmitter is connected, the USB drivers will need to be installed from the
CD using the Hardware Update Wizard.
To test the connection:
1. Choose the appropriate module from the Select Device drop-down list.
2. Click Configure on the main screen to open the Receiver or Transmitter Configuration window.
3. Click Rx ID (or Tx ID).
4. Click Read.
The serial number, model number, firmware version and last programmed date should appear in the
appropriate fields.
RSS Programming Mode
Programming options are divided into two categories – Global Settings and Channel Settings. When
the receiver or transmitter menu is selected from the main screen, both the global and channel
settings for the current channel are displayed.
The RSS may be used to save a receiver or transmitter configuration to disk. This function allows the
user to save a standard configuration and use it as a starting configuration for all modules. An archive
of configurations from each radio system in operation may also be kept so that replacement radios
can be programmed easily.
NOTE: If the MT-4E Receiver or Transmitter is purchased without the P25 Digital firmware upgrade,
the P25 Digital options will not be available in the RSS.
RSS Service Mode
RSS Service Mode allows tuning, testing and setup of the receiver and transmitter modules. Analog
and P25 Digital test modes, such as Bit Error Rate testing and Test Patterns generation can be
selected by the RSS. Audio Levels, RF Power Output and Reference Oscillator adjustments can also
be performed in RSS Service Mode.

Radio System
Configurations
R epeat er
The MT-4E series receivers and transmitters may be configured in a repeater configuration. The
standard way of setting up a repeater system is to connect the receiver to the transmitter through a
Radio Interconnect Cable plugged into the RJ45 CNTL BUS connectors on the front panels of each
radio module. This cable routes analog and digital COR / PTT signals and LVDS Serial Data from
the receiver to the transmitter in both analog and P25 Digital mode. The Radio Interconnect Cable
may be connected directly from the receiver to the transmitter, or may be routed through a Repeater
Control Card.
A typical configuration is to set up the repeater to re-transmit an incoming signal in the same mode as
it is received (i.e., normally, you would want a received analog signal to be repeated as analog and a
received digital signal to be repeated as digital). This requires the receiver and transmitter modules to
be programmed in Mixed Mode of operation through the RSS. The repeater may also be programmed
to operate in analog or P25 Digital mode only.
Mixed Mode Repeat operation occurs as follows:
1.
The receiver determines whether an incoming signal is analog or digital and asserts either the ANALOG
COR or DIGITAL COR signal line on the front panel RJ45 CNTL BUS connector. LVDS Serial Data is sent to
the RJ45 CNTL BUS connector as well.
2.
The COR signal and LVDS Serial Data are transferred over the Radio Interconnect Cable directly to the
transmitter or are routed through a Repeater Control Card.
3.
The transmitter senses the incoming ANALOG PTT or DIGITAL PTT signal from the front panel RJ45 CNTL
BUS connector and keys up in analog mode or P25 Digital mode. LVDS Serial Data is routed through the
transmitter for transmission.
An alternate way of setting up a repeater system is to connect the receiver to the transmitter through
an Audio Control Card or Base Controller. These control cards route analog audio and a single
COR / PTT signal from the receiver to the transmitter. This configuration is recommended for analog
repeater systems only.
The receiver and transmitter have no connection between them apart from the audio (Audio Control
Card or Base Controller only), COR / PTT signals and LVDS Serial Data lines. The transmitter does
not get any information from the receiver about which frequency or channel number to key up on.
The receiver and transmitter channel is determined by the state of the channel select lines and bank
select line.

Radio System Configurations
An a lo g Fixed (Base ) Stati on In terface
The MT-4E series receivers and transmitters may be configured in a fixed (or base) station
configuration with an analog interface. An Audio Control Card or Base Controller is added to the
system for E&M control. For tone remote control of the system, a Tone Remote Adapter is added to
the system along with the base controller. The audio control card or the base controller will also allow
for repeat capability of the system using analog audio as the repeat path.
The base controller is used for system control of encryption and decryption of the P25 Digital voice
messages. Optional decryption or encryption modules are required in the receiver and transmitter
modules.
Digita l F ixed (Base ) Stati on In terface
The MT-4E series receivers and transmitters may be configured in a fixed (or base) station

VHF & UHF Hardware Tuning
and Troubleshooting
R epair N ote
MT-4E Receivers and Transmitters employ a high
percentage of surface mount components which
should not be removed or replaced using an
ordinary soldering iron. Removal and replacement
of surface mount components should be
performed only with specifically designed surface
mount rework and repair stations complete with
Electrostatic Discharge (ESD) protection.
When removing surface mount solder jumpers, it
is recommended to use solder wick braid in place
of vacuum-type de-soldering tools. This will help
prevent damage to the circuit boards.

It is recommended that the radio communications test set be frequency-locked to an external
reference (WWVH, GPS, Loran C) so that the high-stability local oscillator may be accurately set.
Complete Receiver and Transmitter Alignment
A complete receiver and transmitter alignment is performed at the factory and should not be required
under normal circumstances. A large change in receiver or transmitter operating frequency, as
discussed in the next section, or a replacement of major receiver or transmitter sub-assembly
modules, may require a complete realignment operation.

R eceiver Tr oubleshooti n g
The receiver is composed of four main components; the receiver mainboard, the synthesizer module,
the RF Preselector and the universal daughter board (UDB). An optional decryption module can be
installed in the receiver.
The following steps will help you determine the most likely sub-assembly that contains a fault and
may help you determine why the fault is occurring.
NOTE: The sub-assembly or the entire receiver can be sent back to Daniels Service section for
repair. Contact Daniels Service section before returning any product.
Before testing, the receiver should be in the subrack or connected to the subrack by means of an
Extender Card or kit. The main power to the system (+13.8 VDC) and the +9.5 VDC regulated supply
should be checked via the front panel of the system regulator.
Testing the Receiver
1.
Flip the receiver front panel ON/OFF switch from the OFF position to the NORM position.
2.
Check that the two front panel LEDs both turn ON for less than five seconds and then turn OFF.
If this is not the case, the most likely fault is on the UDB, on the synthesizer, or on the receiver mainboard.
Make sure that the UDB and the synthesizer module are properly seated on the receiver mainboard.
3.
Connect the receiver to the PC with the USB cable and run the Radio Service Software (RSS).
4.
Select [P25 or Analog] Receiver.
5.
Click Configure.
6.
Click Read to read the receiver configuration.
If the RSS returns “Device Not Responding,” physically inspect the USB cable and connection, check the
Daniels USB driver and check that the USB is recognized by the Device Manager. If the RSS still does not
recognize the connection, the most likely fault is on the UDB.
7.
Click Rx ID.
8.
Click Read to read the Receiver ID.
Confirm that the Frequency Band in the Synthesizer ID Model Number matches the Frequency Band in
the Receiver Global Settings. If the settings do not match, the synthesizer will require replacement or the
programming will need to be changed to match the synthesizer hardware.
If the receiver is still not functioning properly, the module level check should be conducted in the
following order.

Test Points are shown on the VHF / UHF Receiver Jumper and Test Point Locator Illustrations.
If the test point voltages are within the specified range, the following tests further verify that the
receiver mainboard may not be the source of problem.
Apply a -30 dBm IF signal of the frequency specified (see the VHF and UHF Receiver Performance
Specifications data sheet) to the receiver mainboard IF Input SMB connector. If the signal is properly
demodulated it proves that the receiver mainboard and UDB are in working condition. Proceed to
troubleshooting the synthesizer and UDB module.

Synthesizer and UDB Module
The Synthesizer Module and UDB are bound together through their communication link. At this level
of fault diagnosis it is not feasible to isolate the problem between the two units.
If the receiver front panel ON/OFF switch is set from the OFF position to the NORM position and the two
front panel LEDs stay on, check that the synthesizer and the UDB are properly seated on the receiver
mainboard and check the following test points on the UDB. To access the UDB, the shield lid covering
the UDB will need to be removed.

If the UDB voltages are not within the specified tolerances, it is most likely that the receiver
mainboard (which supplies these voltages to the UDB) is faulty or there is a short within the UDB.
If the UDB voltages are within the specified tolerances, inject a -70 dBm carrier on the receiver
frequency into the RF input and check the RSSI meter reading in RSS Service mode. If the RSSI
meter reading is low (< 30), perform the following test to verify that the synthesizer is locked on
frequency:
Disconnect the LO output SMB connector from the synthesizer to the RF Preselector and connect the
synthesizer LO output to a radio communication test set. Confirm that the synthesizer LO frequency
matches the Target Synthesizer RF OUT found in the “Reference Oscillator” field of RSS Service
mode. The LO output should be approximately +7 dBm.
The frequency of the synthesizer LO output will be above or below the receiver frequency by the
IF frequency (see the VHF and UHF Receiver Performance Specifications data sheet). Check that
this output is within the tolerance for the local oscillator frequency stability (see the VHF and UHF
Receiver Performance Specifications data sheet). Also ensure that the RF frequency will change with
programmed channel changes in the RSS.
Receiver RF Preselector
Check the +9.5 VDC power supply wire to the RF Preselector. The supply voltage should be
+9.5 VDC ± 5 %. Inject a -30 dBm carrier on the receiver frequency into the RF Input and check that
the IF Output of the RF Preselector is equal to the specified IF frequency (see the VHF and UHF
Receiver Performance Specifications data sheet) and the output can be demodulated through the
communication test set. If this is not the case, the synthesizer or the RF Preselector, or both, are
faulty.
To further isolate the fault, the LO output can be disconnected from the synthesizer and an LO input
can be applied from an external source to the RF Preselector. The frequency of the external LO input
should be the Target Synthesizer RF OUT found in the “Reference Oscillator” field of RSS Service
mode. Check the 21.4 MHz output of the module using a communication test set.

If the UDB voltages are not within the specified tolerances, the transmitter mainboard (that supplies
these voltages to the UDB) is most likely faulty. If the UDB voltages are within the specified
tolerances, it is likely that the synthesizer or the UDB, or both, are faulty.
If the transmitter front panel NORM/OFF/ KEY TX switch is set from the OFF position to the NORM
position; the two front panel LEDs both turn ON for less than two seconds and then turn OFF; and the
RF output power control is set at its maximum in the “Power Levels” field of RSS Service mode, but
the RF output power is considerably less than 8.0 W:
•
Ensure that Synthesizer Reference is set to Internal in the “Jumper Settings” field of RSS Service mode.
•
Ensure that the output of the synthesizer module on the RF cable is 0 dBm (± 2 dBm) and that the RF
frequency will change with programmed channel changes in the RSS. If this is not the case, it is likely that
the synthesizer or the UDB, or both, are faulty.

approximately 0.5 to 8.0 W for VHF and UHF models.
Check the following pins on Connector J1 (while the transmitter is keyed):
Pin
Signal Monitored

+0.5 to +3.0 VDC
Regulated +9.5 VDC from motherboard
+9.5 VDC ± 5%
Voltage from motherboard +13.8 VDC line
+13.8 VDC**
If Pin 1 is not within tolerance, the most likely fault is in the UDB or synthesizer module. If Pins 1, 2
and 3 are within the specified tolerances and there is no RF output power, the most likely fault is in
the amplifier.
To test the RF power amplifier sub-assembly, set the output power to maximum using “Power Level
Adjustments” in RSS Service mode, and drive the input of the amplifier with a 0 dBm RF signal. Check
that the RF power output is 8.0 W when the front panel switch is set to KEY TX.

If the radio system is not receiving or transmitting on the right frequency, check the Channel and Bank
Select lines of the receiver and transmitter modules. The motherboard has jumpers that allow one of
16 channels to be selected on a receiver or transmitter. The factory default is to have them all set to
ground the channel select lines CSEL 0 through CSEL 3, forcing the radio to operate on Channel 1.
On the receiver and transmitter there is also a Bank A/B line which usually floats high – selecting
Bank A. The receiver and transmitter have separate control of their channel select lines, so changing
receiver channels does not affect the transmitter channel.
If the Radio Service Software is failing partway through a read or write of the receiver, check that the
receiver is not squelching and unsquelching repeatedly during the read or write operation. Disconnect
the RF signal source from the receiver during the read or write operation.
