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.
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.
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.
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.

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.
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. 6888882V04 RCK1000 Owners-Guide-v4.

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. Proper grounding is essential for your safety, and for good communication performance. Warning Do not touch the antenna and the RF connectors while the 1KW amplifier and/or the exciter (RM125/RM125R or equivalent) operates.
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.
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.
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.
Installation Procedure Note All the information appearing in this section is presented for the Micom 1KW amplifier set and the RM125/RM125R as exciter. For more data on RM125/RM125R, refer to the “RM125/RM125R Owner’s Guide”, Publication 6888882V02. Refer to Figure for a typical RCK1000 interconnection diagram . 1.

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.
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.
All the front panel indicators flash together a few times as the unit performs its power-up initialization sequence, and then turn off If the FAULT indicator lights, a fault has been detected in the 1KW amplifier (you may read the 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.
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.
fully counterclockwise, beyond the detent position. Now set its AC power switch to OFF. Note At this stage, the 1KW amplifier is also turned off. 2. Turn the PS unit off by setting its ON/OFF switch to OFF. 6888882V04 RCK1000 Owners-Guide-v4.
