SELECTED USED ITEM ASSESSMENT SHEET
THE ULTIMATE TECHNOLOGICAL INVOLVEMENT IN SDR TECHNOLOGY
We offer in spectacular, literally **like new**, condition the most desired SDR transceiver for DX, contesting, and high-precision spectrum monitoring enthusiasts: the **SunSDR2 DX** by Expert Electronics. This device represents the ultimate evolution of the HF/6m/2m direct sampling DDC/DUC platform, concentrating a stable transmission power of **100W on HF** in a compact and exceptionally dissipated chassis.
WHY CHOOSE THIS UNIT
-- COMPLETE INSTRUMENTAL VERIFICATION
Before being put on sale, the device underwent a complete cycle of instrumental tests in our technical laboratory. Linear output power, spectral linearity, reference clock stability, and receiver sensitivity are perfectly within factory specifications.
-- FIRMWARE UPDATE AND COMPATIBILITY
The unit is delivered with the latest stable firmware installed and is natively ready to interface with the renowned ExpertSDR3 software ecosystem, ensuring absolute stability on Windows, macOS, and Linux.
-- TOP DISSIPATION AND RELIABILITY
The DX version integrates structural hardware modifications compared to previous series, featuring a massive chassis-heatsink that allows operation in digital modes (FT8, RTTY) or contests without overheating and without preventive power drops (no thermal throttling).
HIGHLIGHTED HARDWARE FEATURES
The SunSDR2 DX accepts no dynamic compromises, thanks to a direct sampling architecture that bypasses the physical limitations of traditional superheterodynes:
- Dual Independent Receiver (Sub-RX): Total coverage from 0 to 65 MHz with two independent physical and software receivers, allowing simultaneous monitoring of different bands or advanced split operations with separate panoramic displays.
- 16-bit Sampling: The 16-bit 160 MSPS LTC2209 analog-to-digital converter (ADC) offers an extraordinary blocking dynamic range (BDR), allowing the extraction of very weak signals close to strong interfering signals.
- Dedicated VHF Output: Native integrated module operating on the 2-meter band (144 MHz), with a clean 20W output for local activities, DX, or satellite transits.
- Ext-Ctrl Port and Interfacing: Immediate management of external linear amplifiers, automatic antenna switches, and tracking systems thanks to the flexibility of programmable control lines.
