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-1X will provide continued use of conventional FM communication while integrating the use of digital communication functions through its unique AMS capability.

The DR-1X is the final release of our popular DR-1 repeater that was released for Beta testing earlier this year. The DR-1X includes several hardware and software changes that improve reliability and external interfacing capabilities.

** Duty cycle is 50% at 50 Watts, 100% at 20 Watts in a climate controlled environment

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

User Friendly Set-Up

The large front panel, color touch-screen permits convenient configuration of the transmitter and receiver frequencies, transmit power output and AMS functions. When the settings are complete the display can be switched off to prevent accidental operation. Simply turn the display switch ON and use the touch panel screen to confirm or change settings. The transmit and receive frequencies, CTCSS tones, squelch, AMS, and other functions are configured by the touch panel screen
