SunSDR2 DX is a direct sampling 100 watt SDR transceiver developed for the serious DX:er and contest operator. It covers all HF bands plus 50 MHz and 144 MHz VHF bands with a general coverage receiver. It combines high performance and 100 watt transmit power in a small package with a LAN interface for maximum flexibility. Remote control over DSL or mobile 3G or 4G connections provide a full SDR experience using the Expert Remote System.

The SunSDR2 DX transceiver based on the well-known SunSDR2 PRO transceiver and features several hardware improvements. It is a 100W-HF; 50W-6M; 8W-2M transceiver, very compact, has a separate connector for active cooling and improved supply system, meaning it’s perfectly suited for DXpeditions and contest operators. Also, we’ve added a separate connector for an external ATU, thus SunSDR2 DX has all the functionality you got used to in our radios and even more. Improved hardware along with the ExpertSDR2 software makes this high-performance SDR transceiver the perfect base station. The evident choice for a true contester!


SunSDR2 DX Improvements

100 watt transmit power on HF, 50 watt on 50 MHz!

New ATU connector for future antenna tuner option

External Fan connector 

External fan included

HPF for VHF (100 MHz) to eliminate strong out-of-band stations coming from HF

LPF for HF (70 MHz) to eliminate strong out-of-band stations coming from VHF

ExtCTRL connector to control external devices with 8 powerful keys with open collector

ALC connector for external power amplifiers*

Supports use of VHF transverters**

An opportunity to use the transceiver as a signal generator via DAC OUT connector (SMA connector)

An opportunity to use external filters in the middle of the RF path, using ADC IN and RX OUT (SMA connector)

Minimal delay in CW mode (about 10 ms)

Input for external 10 MHz reference oscillator

An opportunity to use the transceiver in SO2V mode

Full duplex or half duplex modes***

Antenna switch with 2 HF antenna connectors and separate VHF antenna connector (Mini UHF connectors)

Internal power-meter for HF and VHF bands and SWR-meter for HF band

Ethernet LAN interface provides a fast and reliable connection to PC

* ** *** These functions are supported by the transceiver’s hardware, but is not implemented in the ExpertSDR2 software. They will be supported in the future ExpertSDR2 software releases.


ExpertSDR2 Software

The ExpertSDR2software 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, Linux Ubuntu x64 and MacOS (MacOS currently beta). Minimum hardware requirement Intel Core i3 1.6GHz or higher, video card supporting OpenGL 1.5 and RAM 256 MB or more.


ExpertSDR2 System Requirements

2 or 4 core CPU Intel Core i3 or Core i5;

8 GB RAM;

40 GB free space on the HDD/SSD for the ExpertSDR2 and accompanied programs;

17′ or bigger monitor;

video card with OpenGL 1.5 or higher;

ExpertSDR2 supports Windows 7-10 32/64 bit, Linux (Ubuntu/Kubuntu 18.04 x64), and macOS 10.14 Mojave and higher.
