SunSDR PRO features a high speed LTC2209 ADC for superior BDR, Blocking Dynamic Range, a big heatsink for good cooling, a local oscillator with high stability. The SunSDR2 PRO comes with a 10 MHz reference input as standard. The user friendly but powerful ExpertSDR2 software is included and future updates are free.

SunSDR2 PRO 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 in HF
  • 10 MHz reference input
  • Built-in power-meter and SWR-meter in HF band
  • 8 open collector outputs for control of antenna switches, band pass filters or other accessories.
  • ALC output for external power amplifier
  • PTT input for footswitch
  • CW key input
  • Headphones output, impedance 8-10000 Ohm
  • Microphone input for dynamic or electret microphone
  • Modular microphone input for Yaesu MH-31 or other hand mic with PTT and 3 additional function buttons
  • Polairty reversal protection
  • Ethernet LAN interface with galvanic isolation between transceiver and PC
  • Transceiver’s calibrations are kept inside the device. No need for primary calibration
  • Remote operation possible with CW key and PTT via the E-Coder panel, and RX and TX audio via PC.

* Full duplex mode is supported by the hardware, but is not yet implemented in the software. Full duplex is a planned feature in a future release of ExpertSDR2.

Application field

  • Amateur Radio HF/VHF transceiver
  • SO2R/SO2V contest radio
  • MO2R – two operators in Run & Multiplier station applications
  • Spectrum analyzer with the spectrum scope up to 80MHz
  • Record frequency spectrum for later playback
  • Clean operating position controlling radio over LAN
  • Remote Control via DSL or mobile 4G or 3G connection


The ExpertSDR2 software package is used to control the SDR transceiver. In receiving mode the software provides two independent receiving channels with up to 312 kHz bandwidth. Each receiver has its own sub receiver. ExpertSDR2 runs under Windows XP/7/8/10 x32 or x64 and Linux Ubuntu x64. Minimum hardware requirement are an Intel Core i3, video card supporting OpenGL 1.5 and RAM 256 or more RAM.


The SunSDR2pro transceiver can be delivered with an optional WiFi unit.
