SunSDR2 transceiver - is an up-to-date system of the amateur radio communication in the HF and VHF frequency bands with the digital signal processing. This device is designed to work with the PC via Ethernet (LAN) or via WiFi. Receive path is based on the direct conversion principle, transmission path – over the direct synthesis principle.
* ALC functionality is supported by the transceiver's hardware but is not implemented in the ExpertSDR2 software. It will be supported in the future ExpertSDR2 software releases.
The ExpertSDR2 minimal system requirements:
The ExpertSDR2 software supports Windows 7-10 32/64 bit, Linux (Ubuntu/Kubuntu 18.04 x64), and macOS 10.14 Mojave and higher.
Warning! The ExpertSDR2 software for Windows requires Visual Studio Redistributable 2017, you may install it either from the ExpertSDR2 installer or from the official Microsoft website.
Transceiver SunSDR2 configuration
The transceiver can have additional option WiFi unit for work in wireless networks. In accordance with it at the rear panel can be either set or not WA connectors and the delivery set is changed.
In addition to the basic transceiver's configuration can be purchased the following devices:
|General coverage receiver in HF, MHz||0.09...65|
|General coverage receiver in VHF, MHz||95...148|
|Frequency coverage in HF in TX mode, MHz||All amateur frequencies|
|Frequency coverage in VHF in TX mode, MHz||144...148|
|Maximum transmitter's output power in HF, W||20|
|Maximum transmitter's output power in VHF, W||8|
|Blocking dynamic range in HF mode (BDR), dB||120|
|Blocking dynamic range in VHF mode (BDR), dB||>114|
|RF ADC clock frequency, MHz||160|
|RF ADC resolution, bit||16|
|RF DAC clock frequency, MHz||640|
|RF DAC resolution, bit||14|
|Recommended power supply, V||15|
|Supply voltage range, V||12...16|
|Local oscillator's stability, ppm||+/- 0.5|
|Maximum consumption current, А||5|
|Built-in audio codec resolution, bit||24|
|ALC input voltage range, V||0..4|
|Operating temperature, Celsius degree||0...+50|
* More modes can be supported via external software
Specifications are subject to change without notice or obligation and specifications are only guaranteed within the amateur radio bands.
ExpertSDR2 + LogHX + JTDX, by Sergey (RJ7M, ex UA0ZS)
This document describes how to set up ExpertSDR2 + LogHX + JTDX
Main characteristics of the SunSDR2 transceiver are given in the document
Both diagrams can be used for creating two working places with a single SunSDR2 transceiver.
In the document, you can find information about how to connect to external PA. Described the connection to transceiver a fan and relay to control the external BPF, antenna switch, etc.
This schematic diagram provides you to create special control cable by own hands. With this cable, you can connect the SunSDR2 transceiver to VL-1000 power amplifier from Yaesu and control bands switching and PTT mode.
Also, you can use this schematic diagram for building additional cables for control PA, antennas switches etc.
Warning! Software is device-specific! Don't mix software with unsuitable hardware, it may lead to issues that are not covered by warranty!
