YAESU DR-1 144/430 Dual Band C4FM/FM Digital Repeater.
The YAESU DR-1 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.
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-1 Brochure and Manual for installation examples of Repeater Set-Up replacing existing Analog FM Repeater
·Modulation Modes: Conventional FM, 12.5 kHz C4FM Digital (V/D Mode, VFR Mode, DFR Mode) *
·AMS (Automatic Mode Select) function automatically recognizes the signal as C4FM digital or conventional FM, and then the DR-1 repeater retransmits the signal using the preset communications mode.
·3.5-inch Full Color Touch Panel Operation
·Extremely reliable, high RF Output Power: 50W/20W/10W
·Emergency Operation: Supports auto-switched backup battery power operation.
·Front panel microphone connector is provided for use in repeater transmitter testing, and enables use as a base station.
·Built-in large-size monitor speaker with front panel volume control
*System Fusion is not compatible with the D-STAR GMSK digital format.
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
