4. - ST-2112 RF DESCRIPTION
4.1. Circuit Configuration
LPF
The receiver is a single receiver with
built-in DSP fully integrated.
Incoming signals from the antenna,
after passing through LPF filter, are
fed direct to the DSP down
converter to get the baseband voice
from 0Hz to 3500Hz.
Demodulated signals are filtered
and conditioned onto a second DSP
based filter, which also includes a
high efficiency 4FSK modem.
For digital demodulation, the
recovered data is fed into a vocoder,
which converts the data to voice.
Analog voice from the analog path
or the analog voice recovered from
the vocoder, are fed into an audio
power amplifier.
Transmit signal frequency is
generated by integrated VCO and
PLL. RF frequency generated by the
integrated RF chip is amplified into
a 3-step amplifier then filtered by a
low pass filter to be applied to the
antenna.

AUDIO
PROCESSOR
[U5]
AMPLIFIER
[U10]
The RF signal is tuned by U1, which
includes a base band DSP audio
processing, recovering flat audio
from DC up to 3500 hz.
The detected audio is amplified,
filtered and conditioned inside of
U5 which also includes a deemphasize filtering shape for
received audio signals
The output of the filtered and
conditioned audio is delivered to an
audio power amplifier (U10) then to
the speaker passing through the
external audio connector switch.
4.2.3. Virtual Squelch Circuit
S/N ratio is measured by the
receiver (U1) as the result of the
analysis of the signal and the noise
of the carrier. The output is sent to
the main processor as a digital
frame, which is analyzed by radio
firmware, removing noise then
qualifying the signal level. If the
signal level is higher than the

then the processor analyzes the
expected signaling programmed on
the current channel table.
In case of not any signaling is
required, or the signal has been
detected, the processor ask to the
audio processor (U5) to open the
audio path, unmuting the audio

4.2.6. ANALOG AUDIBLE SIGNALING
DTMF signals, MDC1200 and tone
signals are processed and decoded
by the audio processor (U5).
Decoded information or received
tone is reported to the main
processor (U8).
4.2.4. Virtual VOLUME CONTROL
The potentiometer position (RV1) is
measured by one analog to digital
converter on the audio processor
(U5), and then the information is
reported to the main processor. The
firmware immediately adjusts the
audio processor path gain to get the
appropriate overall circuitry volume
control.
Minimum volume, emergency and
private audio level are controlled
only by software overriding the
information received from the DAC
on U5.
4.2.5. Sub audio signaling
Received sub audio signaling like
CTCSS and DCS are received and
processed by the receiver (U1) then
detected on the audio processor
(U5). Once decoded, the sub audio
signaling is reported to the
processor where the firmware
compares it with the value
programmed into the current
channel programming.
If the received signaling matches
the channel programming, then the
main processor (U8) requests the

5. RC-2112 ALIGNMENT
5.1.
Introduction
The ST-2112 series is carefully
aligned in factory for the specified
performance, across the frequency
range depending for each version.
Realignment should therefore not
be necessary except in the event of
a component failure, or altering
version type.
All component replacement and
service should be performed only by
an
authorized
SmarTrunk
representative, or the warranty
policy may be void.
The following procedures cover the
sometimes critical and tedious
adjustments that are not normally
required once the transceiver has
left the factory.
However, if damage occurs and
some parts subsequently are
placed,
realignment
may
be
required. If a sudden problem
occurs during normal operation, it
is likely due to component failure;
realignment should not be done
until after the faulty component has
been replaced.
We recommend that servicing be
performed only by authorized
SmarTrunk service technicians
who are experienced with the
circuitry and fully equipped for
repair and align. Therefore, if a fault
is suspected, contact the dealer
from whom the transceiver was
purchased
for
instructions
regarding
repair.
Authorized
Smartrunk service technicians
realign all circuits and make
complete performance checks to
ST-2112D SM R 1.2
ensure compliance with factory
specifications after replacing any
faulty components.
Those who do undertake any of the
following alignments are cautioned
to proceed at their own risk.
Problems caused by unauthorized
attempts at realignment are not
covered by the warranty policy.
Also, SmarTrunk reserves the right
to change circuits and alignment
procedures in the interest of
improved performance, without
notifying owners.
Under no circumstances should
any alignment be attempted unless
the normal function and operation
of the transceiver are clearly
understood, the cause of the
malfunction has been clearly
pinpointed
and
any
faulty
components
replaced,
and
realignment determined to be
absolutely necessary.
5.2.
ALIGNMENT:
The following test equipment (and
thorough familiarity with its correct
use) is necessary for complete
realignment.
Correction
of
problems caused by misalignment
resulting from use of improper test
equipment is not covered under the
warranty policy.
While most steps do not require all
of the equipment listed, the
interactions of some adjustments
may require that more complex
adjustments
be
performed
afterwards. Do not attempt to
perform only a single step unless it
is clearly isolated electrically from

except
where
specified
otherwise.
Correct
alignment is not possible with an
antenna.
After completing one-step, read the
following
steps
to
determine
whether the same test equipment
will be required. If not, remove the
test equipment (except dummy load
and wattmeter, if connected) before
proceeding.
Correct alignment requires that the
ambient temperature be the same
as that of the transceiver and test
equipment,
and
that
this
temperature be held constant
between 68°F and 86 °F (20°C ~ 30
°C). When the transceiver is
brought into the shop from hot or
cold air, it should be required to
wait few minutes to come to room
temperature before alignment.
Whenever possible, alignments
should be made with oscillator
shields and circuit boards firmly
affixed in place. Also, the test
equipment must be thoroughly
warmed up before beginning.
Note: Signal levels in dB referred to
in the alignment procedure are
based on 0 dBm EMF = 1 mV.

In case the battery has not enough
charge, the test will be aborted by
the software. Please ensure the
battery has more than 50% of
remaining charge to complete the
test.
5.4.
MAIN RADIO ALIGNMENT
Before setup any parameter, run
SDR programming software then
select Radio Alignment from top bar
menu.
If the radio isn’t connected, then the
program will be timed out after 20
seconds.
As soon as the radio is detected,
actual radio parameters are loaded.
Once the radio is connected, a new
screen pops up showing all
alignment
parameters.
The
software
downloads
actual
alignment parameters stored into
radio memory, so the information
displayed on each alignment step is
the real value form the previous
alignment.
The radio also stores in a special
memory area, original values
assigned in factory. You can go
back to those values anytime for
any particular alignment step.
In case the radio is password
protected, dealer password is
required to access to this alignment
menu.
At any time, press
to end
the alignment procedure then the
radio will returns to alignment
menu.
A complementary message will be
displayed on the time the software
detects the radio connected to USB
port on the computer.
For any transmit related alignment
parameter, low power will be used.

All parameters can be aligned
without relationship to any other,
so there is no an order to align. On
this way, you can adjust only the
desired parameter, avoiding to
waste
time
realigning
other
parameters than required.
Before proceed to align any
parameter, a desired frequency
must be loaded into both TX and
RX. Evenly when the radio has

5.5.2. Transmit Power alignment:
ST-2112 has three power levels to
be selected for each channel. High,
medium and low power level can be
aligned as per radio usage
requirement.
For power alignment, you can do a
fine tuning as per your desire
frequency sub-band. The software
lets you linearize the complete band
“cutting” the complete band into
five steps to let you focus into your
frequency bands.
Even when the software has already
assigned the most convenient

makes the analog voice deviation be
equivalent to the right deviation
produced by 50mV RMS on the
microphone output, and the
selected target gain.
If you want to use AGC, then you
must select the target equivalent
gain on the Mic Gain then check the
ACG Check Box.
For example, if you want a dynamic
gain which causes the same effect
that a gain of 6.4dB when the voice
on the microphone causes 50mV
RMS in the microphone output
(standard voice at 4 inches away
from the microphone), or 0dB gain
on

the other end, produced by 50mV
RMS on the microphone output,
and the selected target gain.
If you want to use AGC, then you
must select the target equivalent
gain on the Mic Gain then check the
Digital ACG Check Box.
For example, if you want a dynamic
gain which causes the same effect
that a gain of 15.0dB when the
voice on the microphone causes
50mV RMS in the microphone
output (standard voice at 4 inches
away from the microphone), or
6.0dB gain on the external
microphone connection, then you
must program the Digital Gain at
15.0dB and the external gain on
