SunSDR2 PRO Main Capabilities

  • Independent RX path based on DDC (Direct Down-Conversion) architecture
  • Independent TX path based on DUC (Direct Up-Conversion) architecture
  • 2 software RXs + SubRX for each of them (4 slices total) + independent wideband Bandscope up to 80 MHz
  • A remote control operation, using it, you connect PTT and CW-key to the E-Coder panel. Microphone and E-Coder are connected to the remotely set up PC
  • TCI interface for seamless connection with third-party software, the list of software with TCI support
  • Professional TX processing module provides the most advanced tuning capability for voice operation
  • ExtCTRL connector to control external devices with 8 powerful keys with open collector
  • ALC connector for external power amplifiers*
  • Supports use of VHF transverters**
  • An opportunity to use the transceiver as a signal generator via DAC OUT connector (SMA connector)
  • An opportunity to use external filters in the middle of the RF path, using ADC IN and RX OUT (SMA connector)
  • Monitoring delay in CW mode is about 5-6 ms
  • Input for external 10 MHz reference oscillator
  • An opportunity to use the transceiver in SO2V mode
  • Full duplex or half-duplex modes***
  • Antenna switch with 2 HF antenna connectors and separate VHF antenna connector (Mini UHF connectors)
  • Internal power-meter for HF and VHF bands and SWR-meter for HF band
  • Ethernet LAN interface provides a fast and reliable connection to PC

* ** *** These functions are supported by the transceiver’s hardware, but are not implemented in the ExpertSDR2 software. They will be supported in the future ExpertSDR2 software releases.

    20W may not sound like a big number, but ample of power for day to day traffic. If you need more output, just put a amplifier behind.
    Nice to be able to run 2m with a useful spectrum view in the normally very uncrowded band.

    Tons of custom settings, super nice filters, waterfall, bandscope, t.eq, etc, etc

    Superb Forum & Support!
