Introduction
This manual covers the installation and operation of the MICOM RCK1000 1KW system. The
MICOM RM125 or RM125R, part of the MICOM-3 line of HF-SSB radio sets, is used as exciter and
controller to for the 1KW amplifier . The amplifier is powered by a separate power supply unit .
The complete 1KW transceiver system is installed in a 19” rack.
1KW System Description
The RCK1000, expands the MICOM-3 product line by offering higher transmit power (up to 1KW,
PEP and average), and thus longer reach and improved communications under bad propagation
conditions and/or strong interference.
The RCK1000 consists of three units placed in rack mounting: RM-125/RM-125R transceiver ,
1KW RF linear power amplifier and an AC-powered PS unit. The equipment is well suited for
base station applications, and can be directly connected to a wide range of broadband or tuned
antennas, including whip, dipole, traveling wave, delta, and semi-delta antennas.
The 1KW amplifier is optimized for operation in conjunction with the RM125 or RM125R radio
set as exciter and controller, using a dedicated communication interface and a flexible
handshaking protocol (interface cable kit, option G156, for connecting the 1KW amplifier to the
RM125/RM125R). The RM125/RM125R controls the 1KW amplifier operation, enables the
operator to select the nominal transmit power, and the 1KW amplifier provides ALC feedback to
adjust the RM125/RM125R drive power to the optimum level.
Caution
Before putting a new RCK1000 into operation, it is necessary to calibrate
the system to obtain the correct transmit power (this calibration must
also be performed after either the exciter, or the amplifier is replaced).
Calibration instructions for the recommended exciter, RM125/RM125R,
appear in the Publication 2072-09538-00, “Radio Service Software (RSS),
User’s Guide” for RSS version V3.0 or higher.
Protection circuits monitor the various operating conditions, and prevent damage to the 1KW
system by taking appropriate action, in accordance with the detected problem.
The RCK1000 has several status indicators, and a front-panel LCD that enables the operator to
monitor the operation of the subunits: active frequency , actual forward and reflected power (or
VSWR), report problems such as the activation of protection circuits or technical malfunctions.
A serial RS-232 asynchronous interface can be used for maintenance and calibration, using any
data communication terminal , and the micom radio programming application.
The 1KW amplifier is active only in the transmit mode: when not powered, in the receive mode,
and also after the protection circuits are activated, the 1KW amplifier switches to the bypass
mode, and directly connects the radio set to the antenna system.

Functional Description
RM-125/125R radio
RM-125/125R radio functions as an exciter in the RCK1000 system.
The RM125/RM125R radio set includes a standard MICOM-3 transceiver, with a 110/220 VAC,
50/60 Hz power supply contained in a compact chassis, suitable for installation in a 19” rack or
desktop. Internal cooling fans allow for continuous-duty data transmission and operation over a
wide temperature range. The radio set features four accessories connectors located on the rear
panel to facilitate the connection of optional accessories.
The AC input voltage range (110/220VAC, 50/60Hz) is automatically switched allowing operation
in the United States of America as well as in other countries. As a backup, the RM125/RM125R
can also operate on 13.8 VDC power from an external lead-gel or lead-acid battery, which can be
automatically charged by the internal AC power supply. When an external battery is connected,
the RM125/RM125R can continue operating on battery power during an AC mains failure. This
feature allow the RCK1000 system to continue working in lower transmit power, with the 1kw
amplifier automatically bypassed , in case of power fail.
Features :
Automatic Link Establishment per FED-1045 & MIL-STD-188-141B standards (JITC
certified).
Full interoperability with other manufacturers' radios complying with the same ALE
standards.
ISB (Independent Side Band) option (option G191).
Remote control option (options G420, G422).
A built-in voice quality system utilizes proprietary algorithms to filter out background
noises, giving users exceptional communication clarity.
Selectable bandwidth allows fine tuning for optimal voice and data communications.
Voice-activated digital squelch.
New control head features a large LCD, full-dot matrix digital display and an enhanced
keypad for programming and set-up.
Multiple language display available.
Transceiver can be controlled using PC and programming application.
Remote control configuration, allows the transceiver to be operated from a remote
location. The optional 2-wire remote control head (option G420) provides control at a
distance of up to 5 km; the G422 6-wire option enables remote control over leased lines,
optical fibers or microwave links, and thus the control range is virtually unlimited.

1KW Amplifier
The 1KW amplifier consists of the following main functions:
Linear RF power amplifier covering the HF band. The RF amplifier consists of 4
independent amplification modules, whose outputs are combined to obtain the required
RF output power. The RF drive signal, applied to the RF IN connector, is amplified to the
appropriate level, as selected on the RM125/RM125R.
Harmonic filter. This is a low-pass filter whose purpose is to attenuate harmonics and
other undesired signals at frequencies above the actual operating frequency, before the
amplified output signal is applied to the RF OUT connector. The filter has 8 sub-bands:
the filter that fits the operating frequency is automatically inserted in the transmit path.
The required frequency information is received from the RM125/RM125R; in addition, the
1KW amplifier measures the actual frequency of the RF drive signal as part of its tuning
process (if the frequency cannot be measured, the highest band is selected).
Bypass circuits. These circuits automatically bypass the 1KW amplifier and establish a
direct path between the RF IN and RF OUT connectors when power is not available, or a
critical malfunction is detected.
Control circuits. These circuits control 1KW amplifier operation, interface with the
exciter/controller unit (RM125/RM125R), and take action to protect the amplifier when
necessary.
Cooling subsystem, includes internal fans that enable operation over a wide range of
temperatures.
Overdrive Protection
The input power is automatically adjusted by an automatic level control to achieve
optimal operating conditions for the amplifier. However, if the input drive power exceeds
about 80W the protection circuits prevent damage to the 1KW amplifier by bypassing it.
High VSWR Protection
To obtain maximum forward power, the amplifier should be connected to a low VSWR
antenna system. In case of excessive VSWR, for example, because of mismatch or damage
to antenna system and/or feed cables, the ALC circuits prevent damage by reducing the
transmit power to safe values.
However, in case of excessive mismatch (for example, short or open circuit), the protection
circuits switch the 1KW amplifier to the bypass mode: in this case, the transceiver is
directly connected to the antenna.
Overheating Protection
Special circuits protect the 1KW amplifier against overheating. If the temperature is too
high to enable full-power operation, the output power is automatically halved, until the
temperature returns to normal. However, if the temperature exceeds the maximum
allowed limit and damage may be caused, the protection circuits are activated and
bypass the amplifier.
6
6888882V04
Imbalance Protection
When a fault, power failure or other type of failure prevents normal operation of one or
more of its internal amplification modules, the 1KW amplifier is automatically bypassed.
PS Unit
The PS unit is a custom design that includes 6 JWS-600-48 standard power supply modules
manufactured by Lambda Inc. (see manufacturer’s manual for complete information on these
modules), contained in a compact chassis suitable for installation in 19” racks. The individual
modules automatically share the load, without any special alignments. The assembled PS unit
has been assigned a custom-design manufacturer number (YM-02-670B).
The PS unit operates on 110/220 VAC, 50/60 Hz. The AC input voltage range is automatically
switched between 110 and 220 VAC, and therefore the equipment can be used in the United
States of America as well as in other countries. Internal cooling fans enable operation over a
wide range of temperatures. The PS unit includes two independent power supply subsystems,
each providing +45V to two of the four amplification modules in the 1KW amplifier. Protection
circuits monitor each output, and provide indications on front panel indicators in case the output
voltages deviate by more than 25% from the nominal value; if an output voltage increases
beyond the maximum limit, the corresponding power supply subsystem is turned off, to prevent
damage to the 1KW amplifier.

1KW PA LCD Functions
The LCD is used to display information on the operational conditions of the 1KW amplifier, and
status information. The LCD comprises 2 rows, and therefore it is necessary to split the
information on four different display pages of 2 rows each.
The first row of each page always presents two items:
The current mode indicator, RX or TX
The operating frequency, in MHz, as detected during the tuning process. The frequency
is measured with a resolution of 10 kHz, and therefore, if you need to know the exact
transmit frequency, always use the RM125/RM125R frequency display.
The information displayed in the second row changes with the specific page. To select a page,
press the DISPLAY MODE push-button display as required (scrolling is cyclical). The selected
page remains on display, until you select another page.
The information presented on each page is explained in the following table. The pages are
presented in the order they appear when scrolling by means of the DISPLAY MODE push-button.

Status screen (shown for receive – RX – mode). Displays the total number
of faults and warnings detected in the unit. If either number is not 0, the
FAULT indicator indicates the condition with the highest severity:
If the condition with the highest severity is a warning (FAULTS is
0, WARNING is not 0), the FAULT indicator flashes
If the condition with the highest severity is a fault (FAULTS is not
0), the FAULT indicator lights steadily
4
Fault (F) or warning (W) screen: displays the fault and /or warning
detected in the unit.
Frequency appears only after successful tuning: before tuning,
and also in case the tuning fails, no frequency is displayed. For
example:
The forward and reflected power (or VSWR) values are automatically updated; fault and warning
information is refreshed only after scrolling again to the same page.

Note
The displayed value may fluctuate, according to the actual power measured at the
instant the display has been updated. As a result, in all the transmit modes except CW
(which has a constant modulation envelope), the displayed value depends on the
instantaneous modulation signal, and therefore may be lower than the selected
nominal transmit power.
Protection circuits are reset after the PTT is released, but may be activated again if condition
persists.

INVALID FREQ
1KW amplifier could not determine
the operating frequency.
The frequency is measured by
automatically causing the
RM125/RM125R to transmit a low
level (about 5W) pilot tone for a few
seconds after each frequency change,
and also whenever the ENT key of the
RM125/RM125R is pressed
Check the cable connections
between the RM125/RM125R and
the 1KW amplifier.
Repeat the frequency measurement
process by pressing the ENT key of
the RM125/RM125R and monitor
the RM125/RM125R display: it
should switch to the transmit mode
for a few seconds, and its transmit
display should include at least two

RCK1000 Equipment Installation
Safety
Warning
During installation work, strictly observe the applicable safety
precautions and local regulations. Do not work on the antenna
system during lightning storms.
Warning
Proper grounding is essential for your safety, and for good
communication performance.
Do not touch the antenna and the RF connectors while the 1KW
amplifier and/or the exciter (RM125/RM125R or equivalent)
operates. During transmission, high RF voltages appear at the RF
connectors, the antenna cables, and on the antenna itself. These
voltages may cause severe injury or death on contact.
Make sure the antenna is not located near high-voltage lines.
All personnel must be familiar with the applicable safety
requirements before attempting to install or operate the 1KW
amplifier and/or the exciter (RM125/RM125R or equivalent). Severe
injury or death could result from failure to comply with the safety
practices.
Warning
High AC voltage, capable of causing death or injury on contact, is
present on the AC INPUT terminal strip at the rear panel of the PS
unit when the unit is connected to a power source.
Caution
The RCK1000 units are a two-person lift. Make sure that help is
available during the installation activities.
Caution
Before putting a new RCK1000 into operation, it is necessary to calibrate
the system to obtain the correct transmit power (this calibration must
also be performed after either the exciter, or the 1KW amplifier, is
replaced). Calibration instructions for the recommended exciter,
RM125/RM125R, appear in the Publication 2072-09538-00, “Radio Service
Software (RSS), User’s Guide” for RSS version V3.0 or higher.

6888882V04
Installation Planning Guidelines
This section provides the additional information necessary for planning the installation of the
RCK1000 system .
Grounding
Failure to provide proper grounding to each system unit (RM125/RM125R, 1KW PA and PS unit,
and to the optional PPS) and to the rack in which these units are installed will degrade system
operation and cause RF voltage to be present on the equipment chassis. A possible serious
hazard to personnel could result, as well as equipment malfunction.
Wide copper straps, as short as possible, must be used for grounding. These straps must be
clamped or bonded to a common grounding point within the rack, which is connected to a
reliable, low-resistance grounding system.
Power Requirements
The RCK1000 PS unit requires AC power at a nominal voltage of 110 or 220 VAC, 50/60 Hz. The
PS unit will automatically select the appropriate voltage range.
The maximum AC power consumption during high-power transmission is up to 5 kW.
In addition to the circuit breaker or fuse protecting the supply line to the RM125/RM125R, a
suitably rated circuit breaker or fuse must be used to protect the supply line of the PS unit, and
enable disconnection of its supply voltage during installation and maintenance.
Cooling
RCK1000 units are cooled by internal fans. Air is taken in through the front panel vents, and
discharged toward the rear. Therefore, make sure that sufficient free space is available around
the equipment to enable free air flow.
Do not stack equipment units: leave at least 1U free above and below each unit installed in the
rack.
Installation Data
The RM125/RM125R, the optional Pre-Selector/Post-Selector (PPS) , the 1kW PA and the power
supply , are intended for installation in the provided 19” rack. The interface cable kit for MICOM
1KW linear amplifier, option G156, is also intended for installation in the same rack.
Each equipment unit has front-mounted brackets for attachment. To provide convenient access
during maintenance, each equipment unit is installed on slides capable of supporting the
equipment weight.
The rack itself must be securely fastened to the floor, before starting the installation activities.
Sufficient front and rear clearance is required to permit convenient access to front and rear
6888882V04

panels, as well as for removal and installation of equipment units, connection of cables, and
maintenance.
Antenna System
Antenna systems are selected in accordance with the specific communication requirements of
each customer: many HF antenna types are available, each providing different radiation
characteristics to meet different communication requirements. Therefore, the selection and
installation of an antenna system is customer’s responsibility. If necessary, contact the
manufacturer or your local representative for additional information.
The antenna system must provide a matched termination at the operating frequency, and must
be capable of handling the maximum power output of the system.
Antenna Feed System
The antenna feed system comprises any cables, panels and matrices, and any accessories that
carry HF signals between the RCK1000 and the antenna itself.
The high output power of the RCK1000 requires particular attention to the power rating of the
antenna system, and to the use of a high-quality, low-loss feed cable. Appropriate safety
measures must be taken to prevent people from touching the antenna, or even getting close to
it.
All the antenna feed system components, and in particular the feed cable, must have low loss
and be capable of carrying the maximum power output of the RCK1000. Remember that any
power loss along the cable is signal loss!
To protect yourself and the radio equipment against lightning strokes and accidental contact of
antenna and/or feed cable with high voltage lines, a properly grounded coaxial protector must
be installed at the point of entry of the feed cable into the building or communication shelter.
The recommended protector type is IS-B50LN-C0 by PolyPhaser Corp. (also available from the
manufacturer as Cat. No. 2072-09128-00).
26
6888882V04
Preparations for Installation
Before starting the installation of an RCK1000, review the installation plan and make the
following checks:
1. Check that the rack is securely fastened to the floor.
2. Check the mounting surfaces, and the rack mounting holes. Thoroughly clean the
mounting surface and remove all paint, grease and dirt from the holes to provide a better
grounding connection.
3. Check availability of AC power, and grounding arrangements.
4. Check antenna installation, in accordance with the antenna installation and operation
manual.
5. Check the cable runs between the 1KW amplifier and the prescribed antenna, including
the coaxial protector. Make sure that the cables are securely fastened, and do not show
signs of external damage.
6. Make sure that you have the cable sets needed for the installation, which includes the
amplifier cable set, and cables for connecting to the exciter unit (for example, use the
cables in option G156 for connecting to the RM125/RM125R).

RCK1000 Operation
General
The following instructions present operating procedures of the system. More information is
detailed in the “RM125/RM125R Owner’s Guide”, Publication 6888882V02, “Owner’s Guide,
MICOM-3F/3T/3R HF-SSB Transceivers”, Publication 6886867J01, and the applicable MICOM-3
Supplements that cover optional features.
Preparations for Operation
1. Set the REMOTE CONTROL switch on the rear panel of the RM125/RM125R to the OFF
(down) position.
2. For the RM125R, set the internal speaker switch to ON (up).
Calibration Procedure
The manufacturer calibrates new 1KW amplifier systems, to ensure that the RM125/RM125R
transmit level matches the 1KW amplifier requirements at each of the four system transmit
power levels (LOW, MED, HIGH, and MAX). However, after replacing the 1KW amplifier or the
RM125/RM125R serving as its exciter, it is necessary to calibrate again the system.
Calibration instructions for a 1KW amplifier used in conjunction with the RM125/RM125R are
given in “Chapter 12: Technician Mode” of Publication 2072-09538-00, “Radio Service Software
(RSS) V3.0, User’s Guide” (previously Publication 68P02953C05-O).
The calibration procedure is described in Section 12.2: “Power Calibration” of the RSS User’s
Guide. Before carrying out the procedure, make sure to select the 1KW amplifier power word
option on the window that is opened by selecting Technician>Calibration. The calibration must
be performed for each transmit level. The nominal transmit levels are as follows:
LOW: nominal transmit power of 300W.
MED: nominal transmit power of 500W.
HIGH: nominal transmit power of 800W.
MAX: nominal transmit power of 1000W.
Exceeding the maximum rated power of the 1KW amplifier (1000 W) may damage the
equipment, and therefore it is highly recommended to adjust the MAX transmit power to 900W
(that is, 0.5 dB below the rated maximum). This is a precaution that takes into consideration the
accuracy of the equipment used to measure the output power.
30
6888882V04
Note
If no equipment capable of measuring the 1KW amplifier transmit power is
available, it is possible to use the 1KW amplifier own display to determine the
transmit power. Do not use this method, unless it is absolutely impossible to
obtain appropriate test equipment.
Equipment Turn-On
1. Apply power to the RM125/RM125R by setting its AC power switch to ON (up).
2. Set the AC power switch on the PS unit to ON, and monitor its indications. The expected
indications, as well as what to do if a problem is detected, are described in the below
table.
3. Turn the RM125/RM125R ON/OFF switch and volume control clockwise and adjust for a
comfortable listening level.
4. The 1KW amplifier is also turned on. Monitor its power-up indications. The expected
indications, as well as what to do if a problem is detected, are described in the below
table.
5. Select the prescribed channel and operating mode of the RM125/RM125R. Make sure
that the RM125/RM125R is programmed to use the 1KW amplifier (you should see AMP
on the PROG>RAD>OPTS>ACC menu).

problem by means of its from panel LCD). Service
the 1KW amplifier.
However, you can still transmit and receive using
the RM125/RM125R by selecting NONE on the
PROG>RAD>OPTS>ACC menu.
If the BYPASS indicator lights while in the transmit
mode, make sure to select AMP on the
RM125/RM125R PROG>RAD>OPTS>ACC menu.
The 1KW amplifier tunes to the
RM125/RM125R operating
frequency. After successful tuning, its
front panel LCD displays the selected
frequency
Check for proper connection of the RF and control
cables between the RM125/RM125R (or other
exciter unit you are using), and the 1KW amplifier.
If tuning fails even after turning the equipment off
and on again in the proper turn-on sequence
described above, you are still able to transmit and
receive using the RM125/RM125R by permanently
bypassing the 1KW amplifier. For the
RM125/RM125R, you bypass the 1KW amplifier by
selecting NONE on the PROG>RAD>OPTS>ACC
menu

The display turns on and shows SELF
TEST for a few seconds.
If the display is too dim, adjust its brightness using
MENU > MORE > DIM > LEVEL. However, this
change is temporary: the dimming level returns to
the default setting (1) after 10 seconds. Each key
pressing will extend the time-out interval by 10
seconds. If automatic dimming is enabled (DIM is
YES), the display may turn off after a few seconds of
inactivity. To cancel this feature, use MENU > MORE
> PROG > RAD > PRMT > MORE > MORE > DIM to
select NO for DIM.
If the self-test procedure is
successfully completed, the radio
automatically resumes operation in
the last used mode (CHAN, FREQ,
ALE, or SCAN).
If a problem is detected during self-test, the display
shows ERR and a code number, followed by a
concise description of the error (if the description
does not fit in one row, its parts alternate in the
display). If the detected problem does not prevent
using the radio, press EXIT to cancel the display
and continue

6888882V04
Operating Instructions
You are now ready to start using the radio set. For the additional operating procedures, you may
use the information appearing in the “RM125/RM125R Owner’s Guide”, Publication 6888882V02,
and in the “Owner’s Guide, MICOM-3F/3T/3R HF-SSB Transceivers”, Publication 6886867J01.
1. During reception, you will see the receive indications (RX and the operating frequency)
on the 1KW amplifier LCD.
Note
The tune indications will appear whenever you change the operating
frequency, and also whenever the ENT key of the RM125/RM125R is pressed.
If the frequency cannot be identified, you will see an INVALID FREQ message,
and it is not possible to transmit using the 1KW amplifier (the 1KW amplifier
is bypassed).
2. When you press the PTT to start a transmission, the TX indicator of the RM-125 and on
the 1KW amplifier lights, and you will see the transmit indications (TX and the operating
frequency) on the LCD.
The second row of the 1KW LCD displays the transmit power, and the VSWR.
Note
During normal transmission, the TX indicator lights, and the BYPASS and
FAULT indicators are off.
If the BYPASS and FAULT indicators light, the 1KW amplifier switched to the
bypass mode because it either overheated to dangerous levels, or the antenna
VSWR is too high, or because it could not identify the operating frequency.
You can read the information displayed by the LCD to get additional details.
In this case:
1. If the operating frequency has not been identified, repeat the frequency
measurement process by pressing the ENT key of the RM125/RM125R
and monitor the amplifier LCD display: it should switch to the transmit
mode for a few seconds, and its transmit display should include at least
two bars.
2. Check that the amplifier cooling fans operate normally, and that nothing
blocks the air intake and exhaust vents.
3. Check the antenna system and the feed cable for accidental
disconnection or damage.
4. If problem persists after turning the equipment off and then on again in
the proper sequence, service is needed.
If the FAULT indicator flashes but the BYPASS indicator is off, the 1KW
amplifier halved its transmit power because it overheated. In this case, take
the steps described in Item 2 above.
Equipment Turn-Off
1. Turn the RM125/RM125R off: turn the front panel ON/OFF switch and volume control
