SunSDR2 Pro Test Report by Adam VA7OJ

Your purchase includes 1 (one) hour of U.S.- based installation technical support (telephone/remote access to your PC). Addition time blocks can be purchased. Hardware warranty is 1 (one) year.

Designed in Russia. Assembled in Taiwan (R.O.C)


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.

SunSDR2 PRO has a DB15 connector for control of external devices. It allows connection to practically any makes and models of power amplifiers, rotators, narrow band pass filters, etc.

The SunSDR2 PRO is perfect for contesting. Powerful and flexible software allows you to create custom designed station Profiles for many different types of contest efforts.

Main capabilities

  • Separate independent receive path based on Direct Down Conversion principle (DDC)
  • Separate independent transmitter, based on the Direct Up Conversion principle (DUC)
  • Full or half-duplex mode *
  • Antenna switch for 2 antennas HF
  • Built-in power-meter and SWR-meter for HF bands
  • External control connector for other devices, 10 powerful keys with open collector
  • ALC connector for external power amplifiers
  • Input connector for connecting PTT footswitch
  • Input connector for connecting CW-key
  • Output Jack for headphones, impedance 8-1000 Ohm
  • Microphone input Jack for electret microphone
  • Microphone connector with PTT switch (Yaesu MH-31 pin-out),which contains microphone, PTT button and 3 additional functional buttons
  • Protection from DC polarity reversal
  • Ethernet LAN interface provides galvanic isolation between transceiver and PC
  • Transceiver's calibrations are kept inside the device. No need for primary calibration
  • Remote operation. PTT footswitch and CW-key are connected to the E-Coder panel, microphone – to the PC

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