DR-1X 144/430 C4FM/FM Digital Repeater
DR-1X 144/430 C4FM/FM Digital Repeater

DR-1X front

The mixed-mode (analog and 12.5 kHz C4FM digital) repeater

The DR-1X can be configured to allow a digital user to transmit in digital and the repeater will convert the digital signal to analog for non-digital users. The repeater is configured via a touchscreen interface on the face of the standard 19″ cabinet-mount unit.

System Fusion is the perfect platform to feed their desire because it brings the right digital solutions to the Amateur VHF & UHF bands. Compared to other Digital modulation methods within FDMA, C4FM is recognized as producing superior audio quality. Equally as important, C4FM provides better reception while you are on the move or receiving challenging weak signals thanks to its better BER (Bit Error Rate) characteristics. C4FM is the principle mode used by professional communication devices in FDMA and is expected to continue to be the leading mode for digital radio communications long into the future.

However, we want you to know that we also strongly believe that conventional analog FM has a number of excellent features that continue to provide substantial advantages over digital modulations, such as low battery consumption and greater distance capability. Therefore, analog FM communications will continue to be the primary method for communication on the VHF & UHF Amateur Radio bands. System Fusion recognizes the continued need for existing conventional analog FM by including a FM Friendly interface; our uniquely flexible DR-1X Repeater that accepts signals from analog FM and FDMA / C4FM digital communication users.

Many Amateur Radio operators have already recognized and enjoyed clear and crisp voice communications provided through C4FM digital communications. It is not just the wonderful audio, though, that makes System Fusion the best Amateur Radio digital communications system. System Fusion is a full 12.5 kHz bandwidth system that includes the ability to transfer reliable high-speed data communications such as text messages, images, and voice memo data – the uses for these impressive features are limited only by your imagination!

System Fusion opens the door to an entirely new era of Digital Communications bringing Amateur Radio communication possibilities that were never possible with other digital solutions in the past.

  • Modulation Mode : 25kHz FM, 12.5 kHz C4FM Digital (V/D Mode, VFR Mode, DFR Mode)
    * System fusion is not compatible with the D-Star GMSK digital format.
  • Output Power :50W / 25W / 10W Equipped with large size heat sink and cooling fan to ensure a stable transmission output.
  • Emergency Operation : Supports Operation on an emergency battery.
  • AMS (Automatic Mode Select) function automatically recognizes whether the signal is C4FM digital or conventional FM signal and transmits using the set communication method.
  • Built in large size monitor speaker with volume control fro checking the reception state during setup. The speaker can also be used to constantly monitor the reception site.
  • A microphone terminal is provided on the front panel for use in repeater transmitter tests and enable use as a base station.

YAESU DR-1X 144/430 Dual Band C4FM/FM Digital Repeater

The YAESU DR-1X is a digital/conventional FM dual mode repeater that covers the VHF and UHF amateur radio bands. It was developed for use with System Fusion. Replacing your conventional FM repeater with the DR-1 will provide continued use of conventional FM communication while integrating the use of digital communication functions through its unique AMS capability .

Easy Migration
The repeater controller, receiver and transmitter are all packaged into a 19” standard cabinet rack mount panel unit for simple replacement of an existing repeater. Existing peripheral devices such as the duplexer and amplifier, etc., can continue to be used as-is.

Please see the DR-1X Brochure and Manual for installation examples of Repeater Set-Up replacing existing Analog FM Repeater
