YAESU DR-2X 144/430MHz C4FM/FM Dual Band Digital Repeater
The YAESU DR-2X is a feature-rich dual-band digital repeater, designed for the modern amateur radio community. Its innovative functionality makes it a great asset for smooth, high-quality communications in both FM analog and C4FM digital modes.
Features
- Modulation Modes: Conventional FM, 12.5 kHz C4FM Digital (V/D Mode, VFR Mode, DFR Mode)*
- VHF or UHF operation (cross-band capable) / Dual Receive / Dual Transmit (DRDT)
- AMS (Automatic Mode Select) function automatically recognizes the signal as C4FM digital or conventional FM, and then the DR-2X repeater re-transmits the signal using the preset communications mode.
- 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
- Full Integrability with existing repeater controllers using the 15 Pin rear I/O connection.
*System Fusion is not compatible with the D-STAR GMSK digital format.
