No Priority - Priority sampling does not occur (all
channels are scanned in sequence). The radio trans-
mits on the selected channel.
Priority/Tx Priority - Priority sampling occurs
and the priority channel is the one programmed in
the selected scan list. The radio transmits on the
priority channel.
Priority/Tx Selected - Priority sampling occurs
and the priority channel is the one programmed in
the selected scan list. The radio transmits on the
selected channel.
Priority on Sel Chan - The priority channel is
always the selected channel (even if the scan list is
programmed with a priority channel). The radio
transmits on the selected channel.
Tal kba ck - No priority sampling occurs. The radio
transmits on the channel of a call while scanning is
halted. Then when scanning resumes, it transmits
on the selected channel.
Scan Timers
Scan Hold Time - Sets the delay that occurs before
scanning resumes after a signal is no longer
received (see Section 2.5.4).
Lookback Time A - This time determines how
often the priority channel is checked for activity.
Times of 0.25-4.00 seconds in 0.25-second steps
can be programmed.
Lookback Time B - This time determines how
often the priority channel is checked once an incor-
rect Call Guard (CTCSS/DCS) or NAC code is
detected. Since it takes much longer to detect an
incorrect Call Guard signal than a carrier, this time
should be relatively long to prevent the interrup-
tions from making a message difficult to under-
stand. Times of 0.5-8.0 seconds can be
programmed in 0.5-second steps.
Priority Channel Selection
The Scan Mode parameter just described selects
if priority channel sampling is enabled on the selected
scan list. It also selects the type or priority channel
(either fixed or selected) if applicable.
If the “Priority/Tx Priority” or “Priority/Tx
Selected” mode is programmed, fixed priority
sampling is selected. The priority channel must then
be chosen for the scan list. To do this, click the
button in the Modify Scan List screen
and then select the desired zone/channel. If any of the
other modes is selected, the priority channel does not
need to be chosen. Refer to Section 2.6.13 for more
information on priority sampling.

Frequency - The transmit and receive frequency of
the control channel. These are the mobile frequen-
cies, not the repeater frequencies. Only multiples of
5 kHz and 6.25 kHz are valid. With 800 MHz fre-
quencies, a receive frequency 45 MHz above the
transmit frequency is automatically entered.
New Entry Button - Click this button to display the
dialog box used to add another control channel.
Trunking Call List Screen
This screen is shown above, and it allows the list
of IDs used for private calls to be programmed. A
maximum of 16 IDs can be programmed (see Section
2.7.4).
To edit this list, click the Trunking Call List tab
and then the “Modify List” button on the right side.
This following information is then programmed in the
dialog box that is displayed:
Entry Number - This box selects the entry to be
edited. The scroll bars to the right of this box select
the desired entry. A phone list can contain up to 16
entries. Selecting a new entry number automatically
validates and stores the current entry. If the current
entry contains an invalid field, the entry number does
not change and the invalid field is highlighted.
Entry Alias - Up to ten characters can be entered to
identify the user being called. This identification is
displayed when the mobile to be called is selected by
the user from the list. Only uppercase letters can be
entered, so lowercase letters are automatically con-
verted to uppercase by the program.
Call ID - This is the ID of the radio being called.
Valid entries are 1-49152. A “0” is detected as no
entry.
Close Button - Verifies the current entry, stores it,
and then closes the dialog box. If the current entry
contains an invalid field, the dialog box does not
close and the invalid field is highlighted.
Priority Monitor Scan Screen
This screen is shown above, and it programs up to
three Priority Monitor scan lists that are allowed. Each
scan list can contain up to 15 channels plus a priority
channel (see Section 2.7.12). These channels must be
from the same SMARTNET/SmartZone system. Chan-
nels set up for other systems are not allowed.
To edit a list, click the Priority Monitor Scan tab
and then click the “Modify List” button on the right
side. A screen similar to the top screen shown above is
then displayed to select the channels to be included in
that scan list. Select channels as follows:

Status Alias - Programs up to 10 characters that iden-
tify the status. This identification is displayed when
the user selects a status condition.
Other Band Trunking Screen
The Other Band Trunking screen follows, and it
is displayed only when programming channels in the
VHF and UHF frequency bands. It is used to define
the relationship between the transmit and receive
channel frequencies in these bands. With 800 MHz
systems, this is not required because the difference
between the transmit and receive frequency is always
45 MHz.
Other Band Trunking Screen
This screen organizes the available frequency
band into three sub-bands, called splits. Each split is
defined by a start frequency, stop frequency, and
channel spacing as follows. Frequencies outside the
defined split cannot be accessed by the radio. These
frequency splits must be defined the same way they
are defined for the trunking controller.
Tx and Rx Spacing - Spacing in kHz between each
potential transmit and receive frequency.
Tx and Rx Start Frequency - Start in MHz of the band
split for transmit and receive frequencies.
Tx and Rx Stop Frequency - Stop in MHz of the band
split for transmit and receive frequencies.
3.6.8 SETTING UP SMARTNET/SMARTZONE

Transmit - Not programmable because the transmit
frequency is dynamically assigned over the
air (“Trunked” is always displayed).
Receive - Dynamically assigned like the preceding
transmit frequency.
Enable This Channel - Not used because SMART-
NET/SmartZone channels are always
enabled if set up. To disable a channel so
that it is not selectable, choose the conven-
tional type and do not check this box.
Copy Parameters From Channel - If another channel
is selected in the box, the parameters from
that channel are copied to the new channel.
Channel Type
Channel Type Box - Selects the specific system from
which the channel is selected. All programmed
systems are displayed by number and type (conven-
tional, SMARTNET, SmartZone). When a different
channel type is selected, the screen for that type of
channel is automatically displayed.
Other Screen Parameters
System Specific Information - With SMARTNET/
SmartZone systems, indicates the system ID
programmed on the system General screen (see
Section 3.6.2).
Talk Group - Selects the talk group selected by that
channel. Talk groups are programmed in the Talk
Group screen described in Section 3.6.5.
Announcement Group - Selects one of up to three
announcement groups selected by the channel. Refer
to “Announcement Group Screen” in Section 3.6.7
for more information.
Emergency Group - Selects the talk group used for
emergency calls.
Talk Permit Tone - When enabled, a short tone
sounds after a request for a group call has been
approved by the main controller. This indicates that
speaking can begin. When disabled, no audio feed-
back is used to indicate when speaking can begin.
System Scan - Selects the Priority Monitor Scan list
selected by the channel (see “Priority Monitor Scan
Screen” description in Section 3.6.7). If “No Scan
List” is programmed, scanning is not selectable on
that channel.
Auto Scan - When enabled and a channel is selected,
the radio automatically begins scanning the scan list
associated with that channel. When disabled, scan-
ning can only be started manually by the Scan option
switch.
3.7 PASSWORD OPERATION
3.7.1 GENERAL
The 50xx portable radio can be programmed with
a Power-Up and Programming password. If the Power-
Up password is enabled, it must be entered each time
power is turned on to make the radio operational. This
prevents unauthorized use. The Programming pass-
word must be entered to access the keypad program-
ming feature of the radio. This prevents unauthorized
reprogramming of the transceiver. Currently, the 50xx
portable is the only transceiver that is programmed
with the PCTrunk software that utilizes password
access. More information on these two passwords
follows.
3.7.2 POWER-UP PASSWORD
The Power-Up password function is enabled on
the Radio-Wide General screen described in Section
3.4.2. This password must then be entered each time
transceiver power is turned on. In addition, since the
radio resets after downloading or uploading data, it
must be entered after performing those functions (see
Sections 3.3.3 and 3.3.4). When entering the pass-
word using the radio keypad, enter the eight password
digits and then press the ENT key. If an error is made,
press the CLR key to start over.
To enable the power-up password function on the
programmer screen, the Power-Up password must be
entered. This prevents the radio from being
programmed with an unknown password which would
make it inoperable. The password is a series of eight
numbers, and it is programmed by clicking the
“Change Password” button on the Radio-Wide
General screen. The default password is eight zeros
(00000000), and it may need to be entered as the “old”
password if applicable. The password can also be

changed using the radio keypad when the keypad is
locked by entering the old password and then pressing
the # key. Refer to Section 2.4.3 for more information.
If the Power-Up password has been enabled in the
radio connected to the programmer, the Programming
password described in the next section must then be
entered before a data can be downloaded or uploaded.
This prevents an unauthorized person from reading
radio data or changing radio programming.
If the password is forgotten, it can be overridden
by pressing the lower button on the side 8 times. This
unlocks the radio and reverts to the default password
of “00000000”. However, it also erases all channel
frequencies, trunked group IDs, and encryption infor-
mation. Therefore, the radio must be reprogrammed
after this is done to make it operational again.
3.7.3 PROGRAMMING PASSWORD
The Programming password must be entered to
enable the Keypad Programming mode described in
Section 2.9. This prevents an unauthorized person
from changing the radio programming. As described
in the preceding section, the Programming password
must also be entered when downloading or uploading
data from a radio that has the Power-Up password
function enabled.

CIRCUIT DESCRIPTION
SECTION 4 CIRCUIT DESCRIPTION
4.1 GENERAL OVERVIEW
4.1.1 INTRODUCTION
The E.F Johnson 5100 series digital portable
radio is a microcontroller-based radio that uses a
Digital Signal Processor (DSP) to provide the
following modes of operation:
Narrowband Analog - FM modulation with a
maximum deviation of 2.5 kHz. This mode is usually
used in systems where the channel spacing is 12.5
kHz. Call Guard (CTCSS or DCS) subaudible squelch
signaling can be used in this mode.
Wideband Analog - FM modulation with a maximum
deviation of 5 kHz. This mode is usually used in
systems where the channel spacing is 25 kHz or 30
kHz. Call Guard (CTCSS or DCS) subaudible squelch
signaling can be used in this mode.
Project 25 Digital - The voice is digitized, error
corrected, optionally encrypted and transmitted using
C4FM modulation according to the Project 25 stan-
dard. This mode can be used in channel spacings of
12.5 kHz.
The DSP processes the received signals and
generates the appropriate output signals. The micro-
controller controls the hardware and provides an inter-
face between hardware and DSP.
PC Boards
This radio contains the following PC boards:
•RF Board
•Digital Board
•Keypad Board
•Four flex circuits that provide interconnection and
support for the volume, on/off, and LED controls.
•Encryption board (optional)
The Keypad Board provides the input/output
interface for the user. It accepts input from the keypad
and the various control knobs and sends the appro-
priate signals to the DSP on the Digital Board and to
the RF Board for proper configuration. It provides the
dual display information to inform the user of the
status of the radio. It also performs all RS-232 commu-
nications between the radio and remote computer
stations for the purposes of radio programming, tuning,
encryption key loading and software downloading.
4.1.2 ANALOG MODE
Receive Mode
The signal is routed from the antenna connector
to the RF Board where it is filtered, amplified, and
mixed with the first local oscillator frequency gener-
ated by the synthesizer. The resulting IF signal is also
filtered and amplified and sent to the ABACUS chip.
The signal is then mixed with the second local
oscillator frequency to create a second IF signal of 450
kHz. The second IF signal is then sampled at 14.4
Msps and downconverted to baseband. The baseband
signal is then decimated to a lower sample rate that is
selectable at 20 kHz. This signal is then routed via a
serial interface using a differential current output to
the ADSIC chip on the Digital Board.
On the Digital Board the ADSIC digitally filters
the input signal, performs frequency discrimination to
obtain the message signal and then routes the message
signal to the DSP. The DSP first performs a carrier-
detection squelch function on the radio. If a signal is
determined to be present, the audio portion of the
signal is resampled to an 8 kHz rate and then filtered
appropriately. The filtered signal is then routed back to
a D/A in the ADSIC to produce an analog signal for
output to the audio power amplifier (PA) and then the
speaker. Any detected signaling information is
decoded and the resulting information is sent to the
microcontroller.

Part No. 001-5100-001
Transmit Mode
The signal from the microphone is amplified by
the audio PA and is then routed to the ADSIC chip
where it is first digitized at a 16 ksps rate and then sent
to the DSP. The DSP performs the required filtering,
adds the desired signaling, converts the sample rate to
48 ksps and then sends the resulting signal back to a
D/A in the ADSIC to produce the analog modulation
signal for the VCO. The modulated VCO signal is then
sent to the RF PA for transmission.
4.1.3 PROJECT 25 DIGITAL MODE
Introduction
In Project 25 Digital Mode, the carrier is modu-
lated with 4 discrete deviation levels. These levels are
± 600 Hz and ± 1800 Hz. Digitized voice is created
using an IMBE™ vocoder.
Receive Mode
The signal is processed in the same way as an
analog mode transmission until after the squelch func-
tion is performed. If a signal is detected to be present,
the DSP resamples the signal from 20 kHz to 24 kHz.
This is done so that the sample rate is an integer
multiple (5x) of the data rate of the digital modulation
which is 4800 symbols/sec (9600 bits/sec).
The resampled signal is then processed by a
demodulator routine to extract the digital information.
The resulting bit stream (9600 bps) is sent to a routine
that performs unframing, error-correction, and voice
decoding. The result of these operations is a recon-
structed voice signal sampled at 8 kHz. The sampled
voice signal is sent to a D/A in the ADSIC to produce
an analog signal for output to the audio power ampli-
fier and speaker.
Transmit Mode
The microphone signal is processed as in the
analog mode until it reaches the DSP. At this point the
audio signal is processed by a voice encoding routine
to digitize the information. The resulting samples are
then converted to a bit stream that is placed into the
proper framing structure and error protected. The
resulting bit stream has a bit rate of 9600 Hz.
This bit stream in then encoded, two bits at a
time, into a digital level corresponding to one of the
four allowable frequency deviations. This produces
16-bit symbols with a rate of 4800 Hz. The symbols
are resampled to a rate of 48 kHz and filtered to
comply with channel bandwidth requirements. The
filtered signal is then sent to a D/A in the ADSIC to
produce the analog modulation signal for the VCO.
The modulated VCO signal is then mixed up to the
final transmit frequency and then sent to the RF PA for
transmission.
4.1.4 RF BOARD
NOTE: The RF Board is not field serviceable. It must
be replaced as a unit with a new board.
The receiver front end consists of a preselector,
RF amplifier, second preselector, and mixer. Both
preselectors on the VHF and UHF board are varactor-
tuned, two-pole filters controlled by the microcon-
troller unit through the D/A IC. The 800 MHz board
uses stripline technology for the preselector. The RF
amplifier is a dual-gate gallium-arsenide IC. The
mixer is a double-balanced, transformer-coupled
active mixer. Injection is provided by the VCO
through an injection filter. See Table 4-1 for local
oscillator (LO) and first IF information.
The frequency generation function is performed
by three ICs and associated circuitry. The reference
oscillator provides a frequency standard to the synthe-
sizer/prescaler IC which controls the VCO IC. The
VCO IC actually generates the first LO and transmit
injection signals and buffers them to the required
power level. The synthesizer/prescaler circuit module
incorporates frequency division and comparison
circuitry to keep the VCO signals stable. The synthe-
sizer/prescaler IC is controlled by the microcontroller
through a serial bus. Most of the synthesizer circuitry
is enclosed in rigid metal on the RF Board to reduce
microphonic effects.

The receiver back end consists of a two-pole
crystal filter, IF amplifier, a second two-pole crystal
filter, and the ABACUS digital back-end IC. The two
pole filters are wide enough to accommodate 5 kHz
modulation. Final IF filtering is done digitally in the
ADSIC.
The ABACUS digital back-end chip consists of
an amplifier, second mixer, IF analog-to-digital
converter, a baseband down-converter, and a 2.4 MHz
synthesis circuit to provide a clock to the ADSIC on
the Digital Board. The second LO is generated by
discrete components external to the ABACUS. The
output of the ABACUS is a digital bit stream that is
current driven on a differential pair to reduce noise
generation.
The transmitter consists of an RF power amplifier
IC that amplifies an injection signal from the VCO.
Transmit power is controlled by two custom ICs that
monitor the output of a directional coupler and adjust
the power amplifier control voltages correspondingly.
The signal passes through a Rx/Tx switch that uses
PIN diodes to automatically provide an appropriate
interface to transmit or receive signals.
4.1.5 DIGITAL BOARD
The Digital Board contains the ADSIC, DSP
(TMS320C50), static RAM, FLASH memory, and a
programmable logic IC. The RF Board and Keypad/
Display Board are connected to the Digital Board. The
ADSIC performs the Frequency Discrimination and
receiver filtering functions. It also performs analog-to-
digital (A/D) and digital-to-analog (D/A) conversion.
The DSP performs demodulation and modulation,
voice encoding and decoding, audio filtering, and
squelch signaling. The software for the radio is stored
in FLASH memory that is loaded in to static RAM at
turn-on. The programmable logic IC controls which
device (Flash, SRAM, or UART) is connected to the
DSP address and data bus.
4.1.6 KEYPAD/DISPLAY BOARD
The Keypad Board contains the microcontroller
(HC08), audio circuits, front LCD display assembly,
display driver, and 5V analog and 5V digital regula-
tors. All interfaces to the side connector and the
switches are on this board. The microcontroller deter-
mines transmit/receive frequencies, power levels, and
display content. It communicates with the DSP via a
serial interface.

4.2 POWER SUPPLY
4.2.1 GENERAL
The radio is typically powered by a battery which
is fastened at the back of the radio. The electrical
contact between the battery and the radio occurs on
probes located on the Digital board (see Figure 4-1).
However the positive battery voltage (UNSWB+) is
directly routed through a small flex circuit (Power
Flex) to contacts located on the bottom of the RF
Board.
The UNSWB+ signal is then routed to the RF
power amplifier module and ALC IC on the RF Board.
It also passes through a fuse and is then routed to the
Digital Board.
The UNSWB+ signal passes through the Digital
Board without being used and is transferred to the
Keypad Board. On the keypad board, the UNSWB+
signal is routed as follows:
•Input of the 5V digital regulator
•Electronic switch which controls the input of the 5V
analog regulator and the “switched RF B+”
•“On/off switch” located on the top of the radio
•Low voltage detector
•Audio amplifier power FET
4.2.2 POWER ON OPERATION
When the user turns the radio on using the top
panel “on/off switch”, the following sequence of
events occur:
1. Power is applied to the shutdown pin of the 5V
digital regulator.
2. The 5-volt digital supply is created.
3. The appearance of the 5V digital supply turns on the
electronic switch which applies the battery voltage
to the “Switched RF B+” line and to the input of the
5V analog regulator.
4. The 5-volt analog supply is created.
5. If the battery voltage is high enough, the low voltage
detector output goes high.
6. The controller sets the control line to the shutdown
pin of the DC/DC converter to a high level.
7. The controller sets the radio in an operational mode.
4.2.3 POWER OFF OPERATION
When the user turns the radio off using the top
panel “on/off switch”, the following sequence of
events occur:
1. The “on/off switch” opens.
2. Power is removed from the shutdown pin of the 5V
DC/DC converter.
3. The controller detects that the power is off through
the pin connected to Switched B+.
4. The controller performs all required save
operations.
5. The controller resets the control line to the shut-
down pin of the DC/DC converter.
6. The 5-volt Digital source disappears.
7. The electronic switch opens.
8. The switched RF B+ and 5V analog sources
disappear.
4.2.4 LOW VOLTAGE DETECT
Low battery voltage is detected by a comparator
chip. When a low voltage condition is detected (less
than 6.3V), the following actions occur:
1. The low voltage detector output goes low which
alerts the controller.
2. The controller prevents any action which could have
a damaging effect (like writing in flash memory).
3. The controller releases its control of the shutdown
pin of the DC/DC converter.
4. The transmitter switches to the low power mode.

5. When the voltage gets really low, the 5 volt DC/DC
converter automatically shuts down.
6. The 5-volt analog and switched RF B+ sources turn
off.
4.3 RF BOARD CIRCUIT DESCRIPTION
4.3.1 FREQUENCY GENERATION UNIT
The Frequency Generation Unit (FGU) consists
of these three major sections: (1) high stability refer-
ence oscillator, (2) fractional-N synthesizer, and (3)
VCO buffer. A 5-volt regulator supplies power to the
FGU. The regulator output voltage is filtered and then
distributed to the transmit and receive VCOs and the
VCO buffer IC. The mixer LO injection signal and
transmit frequency are generated by the receive VCO
and transmit VCO, respectively. The receive VCO
uses an external active device, and the transmit VCO
active device is a transistor inside the VCO buffer.
The receive VCO is a Colpitts-type oscillator.
The receive VCO signal is received by the VCO buffer
where it is amplified by a buffer inside the IC. The
amplified signal is routed through a low-pass filter and
injected as the first LO signal into the mixer. In the
VCO buffer, the receive VCO signal is also routed to
an internal prescaler buffer. The buffered output is
applied to a low-pass filter. After filtering, the signal is
routed to a prescaler divider in the synthesizer.
The divide ratios for the prescaler circuits are
determined from information stored in an EEPROM.
The microprocessor extracts data for the division ratio
as determined by the position of the channel-select
switch and routes the signal to a comparator in the
synthesizer. A 16.8 MHz reference oscillator applies
the 16.8 MHz signal to the synthesizer. The oscillator
signal is divided into one of three pre-determined
frequencies. A time-based algorithm is used to
generate the fractional-N ratio.
If the two frequencies in the synthesizer’s
comparator differ, an error voltage is produced. The
phase detector error voltage is applied to the loop
filter. The filtered voltage alters the VCO frequency
until the correct frequency is synthesized.
In the transmit mode, the modulation of the
carrier is achieved by using a two-port modulation
technique. The modulation for low frequency tones,
such as CTCSS and DCS, is achieved by injecting the
tones into the A/D section of the fractional-N divider,
generating the required deviation. Modulation of the
high frequency audio signals is achieved by modu-
lating the varactor through a frequency compensation
network.
RF BOARD
![](/img.php?id=323477&img=bg1e.png)
CIRCUIT DESCRIPTION
4-6 September 2001
Part No. 001-5100-001
The transmit VCO signal is amplified by an inter-
nal buffer, routed through a low-pass filter, and then
sent to the transmit power amplifier module. The refer-
ence oscillator supplies a 16.8 MHz clock to the synthe-
sizer where it is divided down to a 2.1 MHz clock. This
divided down clock is fed to the ABACUS IC.
4.3.2 ANTENNA SWITCH
A pair of diodes is used to electronically steer the
RF signal between the receiver and transmitter. In the
transmit mode, RF is routed through a transmit switch-
ing diode and sent to the antenna. In receive mode, RF
is received from the antenna, routed through a receive
switching diode and applied to the RF amplifier.
4.3.3 RECEIVER FRONT END
The RF signal from the antenna is sent through a
bandpass filter. The bandpass filter is electronically
tuned by the microcontroller via the D/A IC by
applying a control voltage to the varactor diodes in the
filter. The D/A output range is extended through the
use of a current mirror. Wideband operation of the
filter is achieved by retuning the bandpass filter across
the band.
The output of the bandpass filter is applied to a
wideband amplifier. After being amplified by the RF
amplifier, the RF signal is further filtered by a second
broadband, fixed tuned, bandpass filter to improve
spurious rejection.
The filtered RF signal is routed via a broadband
50 Ω transformer to the input of a broadband mixer/
buffer. The mixer uses GaAs FETs in a double-
balanced Gilbert Cell configuration. The RF signal is
mixed with a first LO signal of about –10 dBm
supplied by the FGU. Mixing of the RF and the first
LO results in an output signal which is the first IF
frequency according to Figure 4-1. The first IF signal
output is routed through a transformer and impedance
matching components and is then applied to a two-
pole crystal filter. The 2-pole crystal filter removes
unwanted mixer products.
4.3.4 RECEIVER BACK END
The output of the crystal filter is matched to the
input of the IF buffer amplifier transistor. The output
of the IF amplifier is applied to a second crystal filter
through a matching circuit. This filter supplies further
attenuation at the IF sidebands to increase radio
selectivity.
In the ABACUS IC the first IF frequency is
amplified and then downconverted to 450 KHz, the
second IF frequency. At this point, the analog signal is
converted into two digital bit streams via a sigma-delta
A/D converter. The bit streams are then digitally
filtered and mixed down to baseband and filtered
again. The differential output data stream is then sent
to the ADSIC on the Digital Board where it is
processed to produce the recovered audio.
The ABACUS IC is electronically program-
mable, and the amount of filtering, which is dependent
on the radio channel spacing and signal type, is
controlled by the microcontroller. Additional filtering,
which used to be provided externally by a conven-
tional ceramic filter, is replaced by internal digital
filters in the ABACUS IC. The ABACUS IC contains
a feedback AGC circuit to expand the dynamic range
of the sigma-delta converter. The differential output
data contains the quadrature (I and Q) information in
16-bit words, the AGC information in a 9-bit word,
imbedded word sync information and fill bits depen-
dent on sampling speed. A fractional-N synthesizer is
also incorporated on the ABACUS IC for 2nd LO
generation.
The 2nd LO/VCO is a Colpitts oscillator. The
VCO has a varactor diode to adjust the VCO
frequency. The control signal for the varactor is
derived from a loop filter.
4.3.5 TRANSMITTER
The transmitter consists of three major sections:
Harmonic Filter, RF Power Amplifier, and the ALC
(Automatic Level Control) circuit.
The RF signal from the PA module is routed
through a coupler, then through the harmonic filter,
then to the antenna switch. The RF power amplifier
module is a wide-band multi-stage amplifier. The
nominal input and output impedance of the power
amplifier is 50 Ω. The DC bias for the RF power
amplifier is controlled by a switching transistor. The
microcontroller uses the D/A IC to produce a ready
RF BOARD (CONT’D)

signal for the transmit ALC IC. The synthesizer sends
a LOC signal to the transmit ALC IC. When both the
ready signal and LOC signal are available to the
transmit ALC IC, the switching transistor for the RF
power amplifier is turned on.
A coupler module samples the forward power and
the reverse power of the PA output voltage. Reverse
power is present when there is other than 50 Ω imped-
ance at the antenna port. Sampling is achieved by
coupling some of the forward and/or reverse power for
rectification and summing. The resulting DC voltage
is then applied to the transmit ALC IC as an RF
strength indicator.
The transmit ALC circuit is the core of the power
control loop. Circuits in the transmit ALC module
compare the RF strength indicator to a reference value
and generate a bias signal that is applied to the base of
a transistor. This transistor varies the DC control
voltage applied to the RF PA controlling the RF
power.
4.4 DIGITAL BOARD
4.4.1 INTRODUCTION
The Digital Signal Processing (DSP) functions
are performed by the DSP chip (U12) and the ADSIC
(U3) with the support of FLASH (U2) and SRAM
(U5, U6) memory devices. Functions previously
performed in hardware like filtering and limiting are
performed by software running in the DSP chip. The
digital board connects with the Keypad Board via J4
and with the RF board via J1.
4.4.2 DIGITAL SIGNAL PROCESSING
OVERVIEW
The DSP section consists of a DSP chip (U12),
the ADSIC (U3), two 128K x 8-bit Static RAM chips
(U5, U6), one 512K x 16-bit FLASH ROM memory
chip (U2), a UART chip (U7), a programmable logic
IC (U1), and two glue-logic chips (U4, U9). The
FLASH ROM contains the program code executed by
the DSP. Depending on the operational mode selected
for the radio, different sections of the program code in
the FLASH ROM are copied into SRAM for faster
execution.
The ADSIC is a support chip for the DSP. It
provides the interface between the DSP and the analog
signal paths, and between the DSP and the ABACUS
chip on the RF Board. Configuration of the ADSIC is
handled primarily by the microcontroller. The DSP has
access to a few memory-mapped registers on the
ADSIC.
In receive mode, the ADSIC interfaces the DSP
with the ABACUS IC on the RF Board. The ADSIC
collects the I and Q samples from the ABACUS and
performs channel filtering and frequency discrimina-
tion on the signals. The resulting demodulated signal
is routed to the DSP via the serial port for further
processing. After the DSP processing, the signal is
sent to the ADSIC Speaker D/A by writing to a
memory- mapped register. The ADSIC then converts
the processed signal from the DSP to an analog signal
and then outputs this signal to the speaker power
amplifier on the keypad board.
In transmit mode the ADSIC Microphone A/D
digitizes the analog signal from the microphone. The
DSP reads these values from a memory-mapped
register in the ADSIC. After processing, the DSP
sends the modulation signal to the ADSIC via the
serial port. In the ADSIC, the VCO D/A converts the
sampled modulation signal into an analog signal and
then routes this signal to the VCO on the RF Board.
4.4.3 RECEIVE SIGNAL PATH
The ABACUS IC on the RF Board provides a
digital back end for the receiver section. It provides a
digital output of I (in phase) and Q (quadrature)
samples which represent the IF signal at the receiver
back end. These samples are routed to the ADSIC
where the signal is filtered and frequency discrimi-
nated to recover the modulating signal.
The recovered signal is sent to the DSP chip for
processing. The ADSIC interface to the ABACUS is
comprised of four signals SBI, DIN, DIN*, and ODC.
The ODC signal is a clock the ABACUS provides to
the ADSIC. Most internal ADSIC functions are
clocked by this ODC signal at a rate of 2.4 MHz and
are available as soon as the power is supplied to the
circuitry. This signal initially may be 2.4 or 4.8 MHz
after power-up. It is programmed by the ADSIC
through the SBI signal to 2.4 MHz when the ADSIC is

initialized by the microcontroller through the SPI bus.
For any functionality of the ADSIC to exist, including
initial programming, the reference clock must be
present.
SBI is a programming data line for the ABACUS.
This line is used to configure the operation of the
ABACUS and is driven by the ADSIC. The microcon-
troller programs many of the ADSIC operational
features through the SPI interface. There are 36
configuration registers in the ADSIC of which 4
contain configuration data for the ABACUS. When
these particular registers are programmed by the
microcontroller, the ADSIC in turn sends this data to
the ABACUS through the SBI.
DIN and DIN* are the data lines in which the I
and Q data words are transferred from the ABACUS.
These signals make up a differentially encoded current
loop. Instead of sending TTL-type voltage signals, the
data is transferred by flowing current one way or the
other through the loop. This helps reduce internally
generated spurious emissions on the RF Board. The
ADSIC contains an internal current loop decoder
which translates these signals back to TTL logic and
stores the data in internal registers.
The ADSIC performs digital IF filtering and
frequency discrimination on the signal, sending the
baseband demodulated signal to the DSP. The internal
digital IF filter is programmable with up to 24 taps.
These taps are programmed by the microcontroller
through the SPI interface.
The DSP processes this data through the SSI
serial port. This is a six-port synchronous serial bus.
The ADSIC transfers the data to the DSP on the TxD
line at a rate of 2.4 MHz. This is clocked synchro-
nously by the ADSIC which provides a 2.4 MHz clock
on SCKT. In addition, a 20 kHz interrupt is provided
on TFS to signal the arrival of a data packet. This
means a new I and Q sample data packet is available to
the DSP at a 20 kHz rate which represents the
sampling rate of the received data. The DSP then
processes this data to extract audio, signaling, and
other information based on the 20 kHz interrupt.
In addition to the SPI programming bus, the
ADSIC also contains a parallel configuration bus. This
bus is used to access registers mapped into the DSP
memory. Some of these registers are used for addi-
tional ADSIC configuration controlled directly by the
DSP. Some of the registers are data registers for the
speaker D/A. Analog speaker audio is processed
through this parallel bus where the DSP outputs the
speaker audio digital data words to this speaker D/A.
In addition, an analog waveform is generated which is
output to SDO (Speaker Data Out).
In conjunction with speaker D/A, ADSIC
contains a programmable attenuator to set the rough
signal attenuation. However, the fine levels and differ-
ences between signal types are adjusted through the
DSP software algorithms. The speaker D/A attenuator
setting is programmed by the microcontroller through
the SPI bus.
The ADSIC provides an 8 kHz interrupt to the
DSP on IRQB for processing the speaker data
samples. This 8 kHz signal must be enabled through
the SPI programming bus by the microcontroller and is
necessary for any audio processing to occur.
4.4.4 TRANSMIT SIGNAL PATH
The ADSIC contains an analog-to-digital (ADC)
converter for the microphone. The microphone path in
the ADSIC also includes an attenuator that is
programmed by the microcontroller through the SPI
bus. The microphone input in the ADSIC is on pin
MAI (U3-19). The microphone ADC converts the
analog signal to a series of data words and stores them
in internal registers. The DSP accesses this data
through the parallel data bus. As with the speaker data
samples, the DSP reads the microphone samples from
registers mapped into its memory space. The ADSIC
provides an 8 kHz interrupt to the DSP on IRQB for
processing the microphone data samples.
The DSP processes these microphone samples
and generates and mixes the appropriate signaling and
filters the resultant data. This data is then transferred
to the ADSIC on the DSP SSI port. The ADSIC gener-
ates a 48 kHz interrupt so that a new sample data
packet is transferred at a 48 kHz rate and sets the
transmit data sampling rate at 48 ksps. These samples
are then input to a transmit D/A which converts the
data to an analog waveform. This waveform is the
modulation signal from the ADSIC and is connected to
the VCO on the RF Board.

CIRCUIT DESCRIPTION
4-9 September 2001
Part No. 001-5100-001
4.4.5 DSP CHIP (U12)
DSP chip U12 has a 16-bit data bus and a 16-bit
address bus. It has 10K words of internal SRAM from
which 0.5K are used only to store data and 9.5K are
used either for data or for program storage. The DSP
bus can access through its buses the following external
devices:
SRAM U5 and U6 - These two chips are 128K x 8
chips. U5 stores the lower byte of the word while U6
stores the higher byte. Those chips are selected by
asserting CE2 high and CE1* low. The programmable
logic IC is responsible for controlling the select lines
of these ICs.
FLASH ROM U2 - This chip is 512K x 16 words in
size. It is selected by asserting CE* low. The program-
mable logic IC is responsible for controlling the select
line of this IC.
ADSIC U3 - The ADSIC contains several registers
which can be read from or written to by the DSP. The
ADSIC IC has an output which drives a data/address
bus enable signal for the programmable logic IC.
UART U7 - This chip converts data from the DSP into
serial data. It is used to interface with the optional
encryption board.
Programmable Logic U1 - This IC arbitrates access
to the DSP’s address/data bus between the flash (U2),
SRAMs (U5,U6), and UART (U7). The DSP can
modify the memory configuration by writing to a
series of registers in the programmable logic IC. In
order to reduce power consumption, the programmable
logic IC can be “disconnected” from the DSP’s
address/data bus using the bus enable input on the
programmable logic IC (pin 44).
The DSP uses memory as data space, program
space, and I/O space as follows. Refer to Figure 4-3
for more information.
Program Space - Internal SRAM, external SRAM,
and FLASH memory.
Data Space - Internal SRAM and external SRAM.
I/O Space - Programmable logic IC, ADSIC, and the
UART.
The DSP accesses the difference spaces by setting
the corresponding lines PS*, DS*, IS* low. Only one
of these three signals can be low at a given time. When
the DSP accesses internal SRAM, none of these lines
is activated.
The programmable logic IC (PLD) acts as the
primary arbitrator of the DSP’s memory map. The
FLASH ROM and the SRAM are both mapped in the
program space and cannot both be active at the same
time. The DSP may control which type of memory is
mapped in program space by enabling the program-
mable logic IC (PLD), then manipulating a register in
the PLD. In addition, the DSP can manipulate other
registers to control paging of both the Flash and the
SRAM. Paging refers to the swapping of 64K word
blocks of Flash or SRAM into or out of the DSP’s
memory map.
FLASH ROM U2 is used to permanently store
the program to be executed in the DSP. However, it is
slow to access, so to fully utilize the speed of the DSP,
the program stored in the FLASH ROM must be
copied into the SRAM. As the size of the SRAM is
half the size of the FLASH ROM, only the code
required for the current mode of operation is copied in
the SRAM. As previously mentioned, the FLASH
ROM and the SRAM cannot be active at the same
time. Thus we use the internal data memory as a
temporary buffer to transfer the program from the
FLASH ROM to the SRAM.
The following hardware interrupts are used on the
DSP:
Connector J2 allows connection to an emulator
for debugging purposes. The emulator connects to
some dedicated pins on the DSP.

phone ADC from ADSIC

CIRCUIT DESCRIPTION
4-11 September 2001
Part No. 001-5100-001
4.4.6 UART
The UART performs parallel to serial and serial
to parallel conversion. The serial format used is a 9-bit
format with start and stop bits. The serial transmission
speed is 19200 bps. The UART appears as eight regis-
ters visible in the I/O space of the DSP starting at
every multiple of 0008h from 0000h to 07FFh. U11
performs the address decoding by selecting the UART
when both IS* and A15 are low. Crystal Y2 along with
the internal oscillator of the UART provides the clock
required to generate the correct bit rate on the serial
output of the UART.
When the UART receives a new serial word or is
ready to accept a new word to send from the DSP, it
generates an interrupt on INTRN. This pin is
connected to one of the hardware interrupt lines on the
DSP. The DSP responds by reading the status register
in the UART and by answering accordingly.
4.4.7 ADSIC
The ADSIC is a complex custom IC which
performs many analog-to-digital, digital-to-analog,
and purely digital functions as previously described.
The ADSIC has four internal registers accessible by
the DSP. They are selected through the use of address
lines A15, A14, A13, A2, A1, A0, IS* (IS* needs to be
inverted with U4 to be compatible with the logic level
required by the ADSIC), RD*, and WR*. Two of these
registers are read-only while the two others are write-
only. Therefore, they can be accessed as two locations
in the I/O spaces. Due to the decoding performed,
those locations appear at the following addresses:
Fxx0h, Fxx1h, Fxx8h, Fxx9h, Exx0h, Exx1h, Exx8h,
and Exx9h.
Crystal Y1 along with the internal oscillator in
the ADSIC provide a 20 MHz clock. This clock signal
is used internally by the ADSIC and is also multiplied
by two to provide a 40 MHz clock to the DSP. The
frequency of the clock can be electronically shifted a
small amount by controlling varicap D1 through the
OSCW pin (U3-97). This removes interference created
on some channels by the clock.
The ADSIC and DSP exchange the sampled
receive data and the sampled VCO modulation signal
through a serial port. This serial port consists of pins
SCKR*, RFS, RxD, TxD, SCKT, and TFS on the
ADSIC. U21 and U1 modify the relative phase of TxD
and TFS to be compatible with the timing required on
the serial port of the DSP.
SDO is the output of the internal speaker DAC.
MAI is the input of the internal microphone attenuator
and is followed by the microphone ADC.
The ADSIC is configured partially by the DSP
through its data and address bus (see preceding).
However, most of the configuring is provided through
an SPI compatible serial bus. This SPI serial bus
consists of pins SEL*, SPD, and SCLK. The other side
of this bus is connected to the controller on the
Keypad Board.
4.5 KEYPAD BOARD
4.5.1 INTRODUCTION
The Keypad Board contains a microcontroller,
LCD Display, Display Driver, Audio circuits, and
Power supply. The Keypad Board interfaces with the
Digital board via J4, with the Top Control rigid flex
circuit via J13, and with the side buttons, PTT switch,
and accessory connector through J5.
4.5.2 FUNCTIONAL DESCRIPTION
The microcontroller provides an interface
between the hardware and the DSP (on the Digital
Board). When the user presses or rotates a control such
as the channel selector switch, a side option or PTT
switch, or a keypad key, the microcontroller signals
the change to the DSP. Conversely, when the DSP
needs to change the display or an LED, it signals the
microcontroller which then performs the action. The
microcontroller also controls peripheral ICs such as
the synthesizer, reference oscillator, display, and
ADSIC.
The microcontroller uses a serial bus to commu-
nicate with the DSP and another RS232 bus to
communicate with the side port connector. The side
connector bus is used for external communication with
a computer running the programming or tuning soft-
ware. Finally, the microcontroller maintains certain
operating parameters in the associated EEPROM
which is controlled via a two-wire serial bus.

CIRCUIT DESCRIPTION
4-12 September 2001
Part No. 001-5100-001
4.5.3 MICROCONTROLLER
The microcontroller is a Motorola
M68HC08XL36 chip. It includes 28K bytes of internal
ROM memory and 1K byte of internal SRAM. It does
not have an external bus and therefore cannot access
any external program memory.
The clock to the microcontroller is provided by
Y1 and an internal oscillator. The frequency of the
clock can be slightly offset by polarizing the base of
Q3 through software control. This prevents RF inter-
ference on some channels caused by the clock.
The microcontroller contains an SPI-compatible
synchronous serial bus. This bus consists of pins
MISO (U1-53), MOSI (U1-52), SPSCK (U1-50), and
a chip enable for each device with which it communi-
cates. The devices which communicate with the
microcontroller through this bus are as follows:
•Top Display driver chip (Top Display board)
•Front Display driver chip (Digital board)
•ADSIC chip (Digital board)
•Reference Oscillator (RF Board)
•Front-End DAC (RF Board)
•Synthesizer chip (RF Board)
•Optional DES board.
The microcontroller communicates with the DSP
chip (Digital board) through a custom serial bus. This
serial port includes pins PTA3 (U1-8), PTA4 (U1-9),
PTA5 (U1-10), PTA6 (U1-11), and PTA7 (U1-12).
The microcontroller uses its SCI asynchronous
serial bus for external communication with a computer
running programming or tuning software. The SCI
pins RxD (U1-42) and TxD (U1-43) are connected to
RS232 driver receiver U5. The other signals of a stan-
dard RS232 computer port (DSR, DTR, CTS, RTS)
are generated using microcontroller input/outputs.
The RS232 driver U5 converts signals from a
logic level of 0 and 5 V to a logic level of –10 and
+10V. The chip contains an internal charge pump to
generate –10V and +10V from the 5V power supply.
The RS232 chip can be put in standby mode by
leaving the line K/F-RS232* floating. This line is
connected to the side connector which allows it to turn
on U5 only when a computer is connected to the radio.
The keypad interfaces with the microcontroller
through eight lines (4 rows x 4 columns). The micro-
controller regularly polls these lines to detect a key
closure.
Serial EEPROM U3 is used to store some impor-
tant radio parameters. The EEPROM is read to or
written from using I/O lines PTC6 and PTC7 of the
microcontroller. PTC6 is used for the Data line, and
PTC7 is used as a clock line.
Shift register U14 expands the number of I/O
lines of the microcontroller. It uses the same data and
clock as the EEPROM plus an additional line (U1-45)
to control the latch. Other user interface inputs such as
the PTT and toggle switches are directly connected to
an I/O line of the microcontroller.
4.5.4 LOW VOLTAGE DETECT
Voltage comparator U4 detects a low voltage
condition and communicates this information to the
microcontroller through the pin PTC5 (U1-30). The
microcontroller can also detect through I/O IRQ2*
(U1-62) that a battery is connected.
4.5.5 LCD DISPLAYS AND DISPLAY DRIVERS
The radio has two displays which each have eight
characters, several icons and a backlight. One display
is located on the Keypad Board while the other display
is located on the Top Display Board. Each display is
driven by its own driver. The drivers are programmed
by the microcontroller through the SPI bus. Both
display drivers are connected to the common PI bus
but are individually addressable so that the displays
may show different information at the same time.
4.5.6 AUDIO CIRCUITS
The audio circuits on the Keypad/Display Board
consist of four op amps, two audio power amplifiers,
and an analog switch.
In receive mode, the analog receive waveform
created by the ADSIC (on the Digital Board) is fed to
an op amp summing amplifier (U9B). This amplifier
sums in the audio tones that are generated by the
microcontroller. The output of the summing amplifier

CIRCUIT DESCRIPTION

is then fed through the volume control potentiometer
to a second op amp buffer.
The buffer output is routed to a pair of audio
power amplifiers: one to drive the internal speaker and
another to drive the external speaker. Only one of
these audio power amplifiers can be active at a time.
The active power amplifier is selected by the OPT
SEL 1 line (J5-12). The MUTE line turns the active
power amplifier on or off by disconnecting the battery
voltage from the audio power amplifier IC using the
transistor Q4. Transistors Q8 and Q9 and their associ-
ated RC networks remove popping sounds from the
speaker audio by delaying the unmuting of the audio
amp compared to the unMUTE command.
In transmit mode, the audio for transmission can
be selected from either an internal or external micro-
phone, depending upon the presence of an external
microphone and which PTT is pressed. An analog
switch is used to route either the internal or external
microphone signal to the microphone amplifier. The
external microphone signal is buffered by an op amp.
The microphone amplifier has a gain of ten, and is
equipped with a pair of clipping diodes to prevent the
amplified microphone signal from over-driving the A/
D input on the ADSIC.
4.5.7 VOLTAGE REGULATION
The 5-Volt Digital Supply is produced by
switching DC-DC converter U12 which operates off
the Unswitched B+ Supply. The switching frequency
is around 160 kHz. A switching regulator is used to
improve efficiency since the 5-Volt Digital Supply
power consumption is a large percentage of the total
power consumption of the radio. The peak-to-peak
residual ripple on the 5-Volt Digital supply is approxi-
mately 50 mV.
The DC-DC converter is controlled by a wired
AND gate on the Shutdown pin of the device. The two
inputs of the wired AND gate are the SW_B+ and the
output PTC4 of the microcontroller U1. When either
input is high, the DC-DC converter is operating.
The DC-DC converter has a soft-start feature
(R98, C136) to prevent chattering of the output regu-
lated voltage due to “bouncing” of the on/off switch.
The converter has current limiting that limits output
current to 1.5 A. The under voltage protection turns
the converter off if the input (Unswitched B+) voltage
drops below 5.45 V.
The 5-Volt Analog Supply is produced by a linear
regulator running from the Unswitched B+ Supply.
The Unswitched B+ input to the regulator is switched
on and off by a FET that is turned on by the 5-Volt
Digital Supply. The peak-to-peak output ripple of the
5-Volt Analog regulator is less than 10 mV which is
appropriate for analog circuits.
4.6 TRANSMIT FREQUENCY
DETERMINATION
The operational frequency of the transmitter is
determined by the PLL (Phase-Locked-Loop)
consisting of synthesizer U204 and VCO circuit Q202/
U201. Reference oscillator U203 generates and
supplies a reference signal of 16.8 MHz to synthesizer.
The synthesizer contains a programmable reference
divider, programmable A and B dividers, a program-
mable prescaler counter (P), and a programmable frac-
tional N divider with two programmable values (N
numerator and N denominator).
All of these dividers are programmed through the
serial interface which connects the synthesizer to the
controller microprocessor. The 16.8 MHz reference
oscillator frequency is divided down to a synthesizer
reference frequency of 2.1, 2.4, or 2.225 MHz. This
signal is fed to the phase detector which generates the
steering voltage for the VCO. The output of the VCO
circuit is coupled back and divided by AP+B and then
divided by the fractional divider and fed into the
second input of the phase detector. The VCO buffer
has two outputs. One input goes to the input of Rx
mixer chip U2, and the other is applied to the input of
power amplifier module U105.
4.7 HARMONIC FILTER
The transmitter harmonic filter consists of C148-
C151, L126, L127, and L128.With VHF models only,
it also consists of C129 and C130. The circuit is essen-
tially a seven-pole low-pass filter. With VHF units
only, two additional poles are inserted by C129 and
C130 which are series resonant with L126 and L127.

5. The computer then attempts to establish communi-
cation with the transceiver. A message is displayed
to indicate success or failure. From this point,
prompts are displayed for each step of the program-
ming procedure.
5.2 TRANSMIT FREQUENCY TUNING
The transmit frequency is set by transmitting on
the indicated frequency and then adjusting the refer-
ence oscillator frequency via the tuning software.
Proceed as follows:
1. Connect a 50-ohm load to the antenna jack and
monitor the transmit signal with a communication
monitor.
2. Set the communication monitor to the indicated
frequency and click OK to key the transmitter.
3. Adjust the frequency by clicking the + and – keys.
The current setting is indicated in the “Current
Value” box. When the frequency is correct, click
OK again to complete the adjustment and store the
setting.
5.3 TRANSMIT MODULATION TUNING
Transmit modulation is set by balancing the
modulation produced by 80 Hz and 3 kHz tones and
then setting modulation limiting using a 1 kHz tone.
All these tones are internally generated by the trans-
ceiver, so no external audio generator is required.
Proceed as follows:
1. Click OK with “TX Modulation” selected. Set the
communication monitor for the displayed
frequency.
2. Click OK to transmit a signal modulated with an 80
Hz tone. Enter the resulting deviation (in hertz) in
the displayed box and click OK.
3. Continue following the screen instructions to adjust
the 3 kHz tone deviation. The + and – buttons are
clicked to set the deviation to the indicated level.
The 1 kHz tone deviation is then adjusted.

4. The preceding 3 kHz and 1 kHz tone adjustments
are then repeated on several other frequencies across
the band. After the last adjustment is made, the
transmitter unkeys and the settings are stored.
5.4 TRANSMIT POWER ADJUSTMENT
Set transmitter power output as follows:
1. Connect a wattmeter and 50-ohm load to the
antenna jack. Click OK with “TX Power” selected.
2. Follow on-screen instructions to adjust for the
displayed power output at various frequencies
across the band.
3. When the last setting is complete, the transmitter
unkeys and the settings are stored.
5.5 RECEIVE SENSITIVITY TUNING
NOTE: This adjustment is not performed with 800
MHz models.
The receiver front end is tuned as follows:
1. Connect an RF signal generator to the antenna jack.
Click OK with “RX Sensitivity” selected.
2. Inject the frequencies and signal levels indicated on
the computer screen. When tuning is complete, a
message is displayed and the settings are saved.
5.6 SQUELCH ADJUSTMENT
NOTE: With some early models, this adjustment
cannot be made using the PCTune software so an error
message is displayed when it is selected.
Test Setup
This adjustment requires access to the receive
audio signal so that SINAD can be measured. It is
recommended that this be done using the RIB (Radio
Interface Box). This box allows the receive audio signal
to be monitored while the computer is connected to the
accessory/programming jack.
Adjustment Procedure
1. Connect an RF signal generator to the antenna jack.
Click OK with “Squelch” selected.
2. Set the signal generator for the indicated frequency
and modulation. Adjust the generator output level
for 12 dB SINAD and click OK.

3. When prompted, adjust the output level for 8 dB
SINAD and click OK.
4. Proceed as prompted and when this adjustment is
complete, a message is displayed and the settings
are stored.
5.7 RSSI ADJUSTMENT
NOTE: With some early models, this adjustment
cannot be made using the PCTune software so an error
message is displayed when it is selected.
This adjustment calibrates the RSSI signal level.
Proceed as follows:
1. Connect an RF signal to the antenna jack. Click OK
with “RSSI” selected.
2. Set the generator for the indicated frequency and
output level and click OK.
3. Select the other output levels as prompted. When
this adjustment is complete, a message is displayed
the settings are stored.
