ICOM Repeater CY-6301
Description
Analog and NXDN Digital Operation
The CY-6301 supports analog FM, NXDN digital, and mixed-mode operation. In mixed mode, the repeater can recognize analog or digital traffic on a programmed channel and retransmit it in the corresponding format. This provides a practical migration path for organizations that are not replacing all subscriber radios at once.
The repeater provides 32 channels in one zone and supports analog CTCSS and DTCS signaling along with digital RAN access codes. A front-panel display, programmable buttons, and internal speaker also allow the unit to operate as a basic local base station.
UHF Coverage and Output Power
The CY-6301 operates across the 400–470 MHz UHF band and provides selectable output levels of 50W, 25W, and 5W. The repeater supports continuous operation at 25W under the manufacturer’s specified conditions, while 50W operation is rated at a 50% duty cycle.
Actual coverage depends on antenna height, building construction, terrain, feed-line loss, interference, and system design. A complete installation may require a duplexer or preselector, suitable antennas, professional frequency coordination, and radio programming.
Rack-Mount System Design
The CY-6301 uses a 19-inch, 3RU rack-mount chassis with an internal AC power supply, temperature-controlled cooling fan, rack handles, grounding point, and rear connections for RF, external equipment, networking hardware, and backup power.
Available internal configurations include:
- Repeater only
- Repeater with receive preselector
- Repeater with notch duplexer
- Repeater with notch duplexer and receive preselector
These options can reduce the amount of separate rack equipment required, depending on the assigned frequencies and installation requirements.
Automatic Battery Backup
The internal power system can automatically switch to a connected external battery when AC power fails. When AC power returns, the supply resumes powering the repeater and recharges the battery. The backup battery is selected separately according to the required runtime and site design.
Expandable System Configuration
Installing the optional UC-FR5300 network/controller board and applicable software can expand the CY-6301 beyond standalone conventional operation. Supported configurations include:
- Single-site trunking
- Multisite trunking
- Multisite conventional operation
- NXDN simulcast conventional operation
- Receiver voting
- Remote programming and monitoring over an IP network
These options allow the repeater system to expand as coverage areas, user groups, and communication requirements grow.
