SunSDR2 DX

SunSDR2 DX is a direct sampling 100 watt SDR transceiver developed for the serious DX’er and contest operator.

The SunSDR2 DX transceiver based on the well-known SunSDR2 PRO transceiver with several hardware improvements.

Like its predecessor, the SunSDR2 DX 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 on HF Bands in a compact size 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.

Hardware improvements in comparison to SunSDR2 PRO:

Improved supply system, which leads to less heating and less power consumption
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
New VHF LNA chip – PGA103+
New high-performance built-in stereo audio codec 24 bit with 114 dB dynamic range
Sturdy DIP-type ExtCtrl connector
New connectors: external tuner control, external fan control, GND
Improved PCB topology

SUNSDR2 DX Price is around 2390 Euro / 2856 USD
