SunSDR2 PRO

The brand new SunSDR2 PRO transceiver is a modern SDR transceiver developed with contesting and DXing in mind. It covers all HF bands plus 50 MHz and 144 MHz and has a general coverage HF receiver. Direct digital signal sampling results in very high performance from a small package. WLAN or LAN opens a lot of possibilities like remote operation, two operators using the same radio, DXing from the sofa etc.

The brand new SunSDR PRO features refinements including a new high speed LTC2209 ADC improving BDR, Blocking Dynamic Range with 10 dB, a bigger heatsink for better cooling, a local oscillator with higher stability and more reliable connectors.

The CE approved SunSDR2 PRO is estimated to be available beginning of June. The first batch might sell out fast, but you can secure your SunSDR2 by pre-ordering it here.

Product Description

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
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

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

Software

The ExpertSDR2 software package is used to control the SunSDR2 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 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.

SunSDR2 configuration

The SunSDR2 transceiver can be delivered with an optional WiFi unit.
