SunSDR2 PRO is a​ direct sampling SDR transceiver developed for serious DXing and contesting.

The SunSDR2 PRO transceiver is designed for advanced use in HF and VHF bands. Even the most experienced operator will be surprised by its capabilities. The modern hardware in a 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 special connector for controlling the external devices. It allows connecting to it practically any power amplifiers, rotators, narrow band pass filters, etc. With a help of this capability your place can become a professional studio for work in the air.

The SunSDR2 PRO is perfect for contesting. Its powerful and flexible software lets you create custom designed station setups 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 in HF
  • Built-in power-meter and SWR-meter in HF band
  • External control connector for other devices, 8 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, which contains microphone, PTT button, and 3 additional functional buttons
  • Protection from 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
  • A possibility of remote work. 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 but is not implemented in the ExpertSDR2 software. It will be supported in the future ExpertSDR2 software releases.

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

Application field

  • Radio Amateur HF/VHF transceiver
  • Remote reception point for contests
  • SO2R/SO2V working contest-station
  • Spectrum analyzer with the spectrum scope up to 80MHz
  • Record air stations with the further reproducing

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
  • OS Windows 7 and newer, OS Linux Ubuntu x64

Software

The ExpertSDR2 works with Windows 7-10 and Linux Ubuntu/Kubuntu.

Architecture description.

Transceiver SunSDR2 PRO configuration

  • Transceiver SunSDR2 PRO
  • LAN-cable for connecting to local network (1.8m)
  • Power cable for connecting the transceiver to power supply (2m)
  • Audio-adapters  JACK 6.3mm to JACK 3.5mm for connecting PC's headset to the transceiver (2 pcs.)
  • RF Cable  Mini UHF — HF (PL259) 1Ft (0.3m 1 pc.)

 

The main improvements in SunSDR2 PRO in comparison to SunSDR2

  1. High-speed ADC LTC2209 instead of LTM9001CV-BA, as a result, the transceiver has higher dynamic range - 129...130 dB instead of 118-120 dB in SunSDR2. It allows you to work with enabled preamp +10 dB alongside strong АМ stations within the octave filters bandwidth, which is very important for 20M, 17M, 15M, with low air noise level and good propagation. The receiver is almost impossible to overload.
  2. LPFs in the power amplifier was increased to 5th order, instead of 3rd.
  3. Improved antenna switch, idle connectors shorted on the case. It eliminates crosstalk from HF antennas while working on the VHF band and vice versa.
  4. BNC antenna connectors were replaced with more reliable mini-UHF.
  5. Improved HF crosstalk protection on all connectors: PTT, CW, MIC.
  6. Added diode protection to ExtCTRL keys. Voltage output +12...+15 V now goes via 1 А fuse and polarity reversal protection on the ExtCTRL connector instead of 5 V.
  7. Improved heatsink - it is a single detail instead of multilayer construction as before.
  8. Improved PCB board - transistors and VHF path are placed in the PCB space with the shortest outputs. Improved PCB structure, added layers from 4 to 6.
  9. And a lot of other small improvements.

SunSDR2 PRO transceiver is optimized for mass production with improvements, which were added after 5 years of manufacturing and extensive usage of the SunSDR2.
