Description

The SunSDR2 PRO transceiver is designed for advanced use in HF and VHF bands. Even the most experienced operator may be surprised by its capabilities. The modern hardware and small physical size makes this high performance SDR transceiver the perfect base station while at the same time very portable for field operations.

Main capabilities

• Independent RX path based on DDC (Direct Down-Conversion) architecture
• Independent TX path based on DUC (Direct Up-Conversion) architecture
• ExpertRemote system provides full remote control of the transceiver
• An opportunity to use the transceiver in the SO2V mode
• Full or half-duplex mode*
• 2 software receivers + SubRX for each of them (4 slices total) + independent wideband Bandscope up to 80 MHz
• Antenna switch with 2 HF antenna connectors and separate VHF antenna connector
• Supports use of VHF transverters
• An opportunity to use the transceiver as a signal generator via DAC OUT connector
• Built-in power-meter and SWR-meter for HF bands
• ExtCTRL connector to control external devices with 8 powerful keys with open collector
• Ethernet LAN interface provides fast and reliable connection to PC
• ALC connector for external power amplifiers**
• TCI interface for seamless connection with third-party software like SDC (with its own Skimmer), LogHX, SWISSLOG and RUMlog, more are coming
• Professional TX processing module provides the most advanced tuning capability for voice operation
• Small delay in CW mode (about 10 ms)

* Full-duplex mode is supported by the transceiver's hardware but is not implemented in the firmware and software yet. This mode will be implemented in future versions of ExpertSDR2 software.

** ALC functionality is supported by the transceiver's hardware but is not implemented in the ExpertSDR2 software. It will be supported in the ExpertSDR2 1.3 software release.

PC requirements

• CPU Intel Core i3 1.6 GHz and higher
• Video card, minimum resolution 1024x600, 128 MB, OpenGL 1.5 support and higher
• Local network connector 100 Mbps or 1 Gbps
• The ExpertSDR2 works with Windows 7-10, OS Linux Ubuntu x64 and macOS 10.12 and newer
