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.

Page 2: Description
TO ORDER – VISIT 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). 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. -
Page 3: Equipment Versions
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. -

Page 11: Equipment Installation
Power Requirements The RM500/RM500R requires AC power at a nominal voltage of 110 or 220 VAC, 50/60 Hz. The RM500/RM500R will automatically select the appropriate voltage range. The AC power consumption during high-power transmission is up to 2 kW. -
Page 12: Preparations For Installation
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. -

RM500/RM500R with option G65 and the PPS are shown in Figure 5. When the G65 option is installed, the PPS is controlled by the RM500/RM500R through serial and parallel ports and is automatically inserted by the RM500/RM500R in the signal path in accordance with the operating mode: •... - Page 14 During self-test, the PPS automatically switches to the bypass mode: in this mode, RF signals pass directly through the PPS, without filtering, and therefore does not interfere with system operation. The PPS also switches to the bypass mode when the RM500/RM500R frequency is outside the PPS operating range, 1.60 to 29.99 MHz.

Bypassing the 500W Amplifier Section The internal 500W amplifier section of the RM500/RM500R can be permanently bypassed. In this case, you can still transmit at a power of up to 125W using the capabilities of the MICOM-3 transceiver which is part of the RM500/RM500R.
