IC-FR3000 & IC- FR4000 Repeater

Bridging the gap between bands

Request Information Datasheet

50 Watt continuous full duty cycle operation

This repeater looks as good as it performs. A rugged heatsink, large cooling fans and a high performance power module provide the repeater with a stable 50W at full duty cycle operation.

Automatic battery backup system

A built-in backup system supports automatic switching to an external power supply (13.6V DC) if the AC power supply fails.

Multiple CTCSS & DTCS tone memories with multiple memory channels

Up to 16 CTCSS/DTCS tones (TX/RX tones respectively) can be programmed in a channel. This feature allows you to share a channel with multiple user groups. You can also give priority/exclusive use to a specified group simply by programming different tones to another memory channel. Ideal for many different applications.

Built-in 2-Tone, 5-Tone, DTMF encoder & decoder

Multiple signaling systems are equipped as standard. These systems are fully compatible with Icom F-series radios.

Internal space for duplexer and isolator

The repeater has an internal space to install a duplexer and isolator*. The controls of the duplexer are accessible from the front of the repeater without disassembly. Faster and easier maintenance and adjustment is possible.

* Ask your dealer for details about available duplexers and isolators.

Telephone interconnect capability

DTMF remote control capability

You can control the repeater from a remote location over the air or over a phone line with DTMF.

Optional wall mount bracket, MB-77 and 19 inch rack mount bracket, MB-78

Additional Features

  • Master/Slave backup operation by connecting two repeaters
