Introduction

The MICOM RM500 (ordering option G160) and RM500R (ordering option G179) are 500W HF-SSB

rack-mount continuous duty transceivers, part of the MICOM-3 line of HF-SSB radio sets.

This manual covers the installation and operation of the RM500/RM500R transceivers. The manual

covers only procedures specific to the RM500 and RM500R; the other procedures, which are

common to the whole MICOM-3 product line, are described in the “Owner’s Guide,

MICOM-3E/3T/3R HF-SSB Transceivers”, Publication 6886867J01, and in the other applicable

MICOM-3 Supplements that cover optional features.

Description General The MICOM RM500 and RM500R are 500W HF-SSB continuous duty radio sets. Figure 1 shows a general view of a typical 500W transceiver (the RM500R). F1 F2 F3 F4 * 0 Figure 1. RM500R, General View RM500 and RM500R expand the MICOM-3 product line by offering higher transmit power and thus longer reach, and improved communications under bad propagation conditions and/or strong interference.

Thus, the RM500 and RM500R will always attempt to transmit at the maximum safe power, even in case of mismatch. Special circuits protect the RM500 and RM500R against overheating and various types of malfunctions. In case a critical problem is detected, the protection circuits are activated and bypass the internal 500W power amplifier: in this case, the MICOM-3 transceiver is directly connected to the antenna.

User-friendliness • New control head features a large LCD, full-dot matrix digital display and an enhanced keyboard for programming and set-up. • Radio operation can be executed using any standard USB keyboard. • 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 (at a distance of up to 5 km) using the optional 2-wire remote control head.

Performance Specifications Main Technical Characteristics This section presents the main technical characteristics of the RM500 and RM500R. For a listing of the additional performance specs, refer to the “Owner’s Guide, MICOM-3E/3T/3R HF-SSB Transceivers”, Publication 6886867J01, and to the applicable MICOM-3 Supplements that cover the optional features available on your radio set.

Accessories Connectors The functions of the 25-pin accessories connectors, ACC-J1 to ACC-J4, are listed in Table 1. The connectors include PTT and CW control lines, audio and baseband lines for external equipment, auxiliary power output, serial RS-232 asynchronous data interfaces, and additional dedicated handshaking and control lines. The functions supported by the serial data interfaces are determined by the RM500/RM500R software. Table 1.

Equipment Installation Warning For general operating and installation safety information, see the “Owner’s Guide, MICOM-3E/3T/3R HF-SSB Transceivers”, Publication 6886867J01. 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 RM500/RM500R operates.
PAGE 12
Cooling RM500/RM500R units are cooled by internal fans. Air is taken in through the front panel vent, 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 the RM500/RM500R. Installation Data The RM500/RM500R are intended for installation in 19 in. racks. The equipment has front-mounted brackets for attachment.

2. Check availability of AC power, and grounding arrangements. 3. Check antenna installation, in accordance with the antenna installation and operation manual. 4. Check the cable runs between the RM500/RM500R and the prescribed antenna, including the coaxial protector. Make sure that the cables are securely fastened, and do not show signs of external damage.
PAGE 14
• In the transmit mode, the PPS is used as a postselector. It attenuates spurious signals and broadband noise in the driver transmit signal before it reaches the internal 500W power amplifier, thereby reducing interference to neighbouring receivers. In both modes, the PPS automatically tracks the RM500/RM500R operating frequency. Rapid tuning makes the PPS suitable for Automatic Link Establishment (ALE) or Adaptive Applications.
