Yaesu DR-2X C4FM Digital Repeater IP Interconnect Dual Band VHF/UHF Receiver System Multifunction Repeater


YAESU DR-2X supports C4FM digital / regular FM dual mode and dual receive function relay platform, which includes VHF and UHF amateur radio band.Through the AMS function, the DR-2X mixes communication using conventional FM mode communication and C4FM digital mode.

1. C4FM digital mode provides perfect audio quality
Compared with other digital models, the C4FM modulation mode has better bit error rate (BER) characteristics to ensure good speech quality in communication. The C4FM digital high definition voice technology using 12.5kHz bandwidth enables the high quality voice communication to be transmitted perfectly.

2. AMS makes conventional FM and digital FM friendly co-exist (automatic mode selection).
System integration enables all users, including users using different modes, to communicate with each other. AMS makes all systems possible. AMS automatically identifies C4FM digital signals or regular FM signals, and then DR-2X transforms the identified signals into the current communication mode.

3. Flexible double receiver function
The unique real-time double receiver relay – DR-2X can assign an additional control relay to the relay administrator, transmit an emergency signal, or specify second uplink frequencies. Relay administrators can also independently allocate downlink frequencies based on uplink frequencies.

4. Enhanced Digital Group ID Function
The revolutionary digital group ID function enables users who share the same digital group identification code to quickly and quickly track multiple communication resources and display group member signal strength and telemetry information.
A group ID (0-99) can specify members to participate in group communication. In addition, multi-point relay transmission can be controlled by DG-ID.
For safe relay station operation, you can register the sole ID of the relay station for personal operation identification. DP-ID can restrict access to the relay station members of registered ID.

5. Based on Internet connection relay link system (IMRS), large area expands signal coverage (option).
The Internet link Relay link system (IMRS) allows relay use to connect multiple relays via LAN or WAN. Based on the inherent stability defects of WAN connection, such as the Internet, or the words happen all happened, the new DR-2X mixed a variety of forms of network environment, making the connection between the relay more direct, ensuring the quality of digital communication. Digital group identifier can be used to control relay activation. * required component LAN unit (LAN-01A)

6. Friendly interactive settings interface 3.5 inch full touch screen7. Advanced operation

The Yaesu DR-2X is a full feature, heavy duty, C4FM/FM dual band repeater/base station. And unlike many other repeaters, the DR-2X handles conventional FM and C4FM digital transmission. The Yaesu System Fusion technology features the AMS – Automatic Mode Select function that instantly recognizes whether the signal is C4FM digital or conventional FM and automatically switches to match the received mode. The front panel features a full color 3.5 inch, high luminescence TFT touch screen display. The rear panel has both AC input and backup DC input. The power input is auto-switched to backup DC input during power outages.
