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
- 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
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.
Whats in the Box
- LAN-cable for connecting to local network
- Power cable for connecting to power supply
- Two 6.3mm phono male to 3.5mm phono female adapters to connect a headset to the radio
- CD with software (latest version always available at SunSDR.euor eesdr.com)
- SMA connector for WiFi antenna (only with WIFI option installed)
- Small-size WiFi antenna (only with WIFI option installed)
Optional Configuration
- WLAN Unit
- 10 MHz reference input
Accessories
In addition to the transceiver we also recommend the following accessories :
- Switched power supply for voltage 15 V current 5A
- Noise cancelling headphones with ModMic boom mic
- E-Coder control panel for ergonomic contest or DX operation
