Expert electronics sunsdr2-dx - hf,6m,vhf transceiver.

Expert electronics SunSDR2-DX - HF, 6m, VHF transceiver.


The SunSDR2 DX transceiver is based on the well-known SunSDR2 PRO model with various hardware improvements. It is very compact for a 100W format, has active cooling, and has an improved supply system, meaning it’s perfectly suited for DXpeditions. Also, it has 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 ExpertSDR2/3 software makes this high-performance SDR transceiver the perfect base station. 

The obvious choice for any radio amateur! Hardware improvements of Gen5 (late 2022) in comparison to Gen1 (November 2019): Redesigned heatsink, with thinner and more frequent gills for higher effectiveness Improved temperature sensor placement for more accurate temperature readings Improved TX IMD3 up to ~37 dB across all HF bands, with 100W output power 6M output power have been increased up to 80W Improved SDR PCB protection from cross-talks. Improved protection for the supply chain Added ferrite bead on the flex-cable connecting PA and SDR PCBs, 

For more stable operation with external ATU Added filtering of the headphones' connector Slight improvement of the RX path TX filter of the DAC chip, which provides better linearity of the TX signal Band pass filter on the PA input, which improves linearity of PA operation Improved structure of 160, 6M TX filters RX/TX switching node on PCB is more resilient now Hardware improvements in comparison to SunSDR2 PRO: 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 (CS4272) Improved supply system, which leads to less heating and less power consumption Active cooling Antenna switch supports Predistortion without external devices Improved topology of SDR PCB Main capabilities Independent RX path based on DDC (Direct Down-Conversion) architecture Independent TX path based on DUC (Direct Up-Conversion) architecture Output power: 100W on HF, 80W on 6M and 8W on 2M 2 software RXs + SubRX for each of them (4 slices total) + independent wideband Bandscope up to 80 MHz Remote control operation, using it, you connect PTT and CW-key to the E-Coder panel. Microphone and E-Coder are connected to the remotely set up PC TCI interface for seamless connection with third-party software, the list of software with TCI support Professional TX processing module provides the most advanced tuning capability for voice operation ExtCTRL connectors 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) Monitoring delay in CW mode is about 2-3 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.
