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.
