Introduction
Please, spend 5 minutes on reading this document and you will be able to start quickly to work with SunSDR2 transceiver and broadcast in a new way today. This document gives answers to the majority of first questions, appearing at a new user who starts working with a transceiver of a new type.
You have bought the most up-to-date radio amateur equipment which can be imagined for today. This transceiver is a compound software defined radio, allowing to provide high quality of signal processing both in receiving and transmitting mode by modern digital methods. PC use in transceiver allows to provide qualitative service not only in receiving/transmitting, but also to use the HAM LOGs and DIGI software without wires.
Effective and quick mastering of SundSDR2 computer transceiver is possible on condition that user has basic skills in using PC. It’s considered that computer terms used in this manual on quick start are familiar to the user and won’t cause any difficulties in searching one or another tab in Windows 7 or Windows XP. For visualization and simplicity, screenshots of dialogue windows will be given here, necessary functions and fields for editing will be outlined with coloured contour.
SunSDR2 transceiver is a software defined radio. It means that you will need PC or laptop for work with transceiver. PC controls transceiver, RX/TX modes, band switching and data rate processing, coming from and to transceiver. These rates by PC at the input and output gives audio signal and receive microphone signal and by transceiver they give HF-signal, transmitting into the air.
The main feature of this transceiver and its basic distinction from all the other recent output transceivers is the use of absolutely new principle of radio signal processing.
There is no frequency converting units in its classical variant. The signal is converted almost from the antenna, all the further signal processing is in the software. The same process is observed while transmitting. Forming of necessary signal modulation type is made by digital method right at the required frequency. From all the classical nodes there is only preselector, power amplifier and low frequency filter for
PA in the scheme.

1. Connection
For starting SunSDR2 transceiver work the following components are required:
· Transceiver power supply unit;
· PC;
· CW key (if it’s required);
· Microphone or telephone headset;
· Computer net LAN – cable;
· Antenna, tuned into radio amateur frequencies.
Let’s have a look at each component.
Power Supply unit must have power not less than 75
W, provide constant voltage of 15 V at the output with 5
Amperes load current. Under 15 V supply voltage transceiver gives full output power of 20 W.
PC or laptop can be of any modern configuration, produced during last 2-3 years. Recommended configuration:
· 2 or 4 cores CPU Intel Core i3 or Core i5
· 2, 4 or 8 Gb RAM
· 40 Gb of available space in hard disk for transceiver and accompanying software.
· 17 – 24” of monitor screen.
· Video card with OpenGL 1.5 or more updated support.
Transceiver software will work with less powerful PC with Core2Duo and Dual Core, but it will cause increased load level and it’s not always good. The more powerful the PC the less resource the software will occupy and the easier and more colourful “waterfall” and panadapter will be painted.
OS must Windows XP 32/64bit or Windows 7 32/64bit.
Information about OpenGL support by video card can be got at the sellers when buying the PC.
Microphone or Telephone headset can be either of the simplest and cheapest as, for example, by Genius, or developed specially for radio amateurs by Heil Sounds.
On the transceiver front panel there is a usual 6,3 mm slot for electret microphone connecting. And also there is a jack, compatible with Yaesu PTT-switches of MH-31 type. This jack allows to connect PTT-switches of such popular transceiver as Yaesu FT-817/857/897 to transceiver.
Receiving/transmitting modes control is produced by pushing the PTT-footswitch (e.g. ЕЕ-РС-01), connected to “PTT” jack on the back panel of the transceiver.
Computer net LAN – cable performs transceiver connection to PC by ETHERNET-connection. PC connection is also possible “by air”, via wireless net. The easiest and quickest transceiver connection to PC is by
LAN-cable, supplied with the transceiver.
Antenna, tuned into radio amateur frequencies must have impedance close to 50 Ohm at those bands where work is planned.

2. Transceiver Ethernet-connection setting
There are several ways of transceiver connecting to PC.
Let’s have a look at each in detail.
Connection by wire net connection is possible in 2 variants – direct connection to PC by wire Ethernet(LAN) interface and by already working local net via router.
Direct connection to PC by wire Ethernet(LAN) interface.
1) Connect your transceiver to PC by LAN-cable, supplied with transceiver.
2) Switch on the transceiver.
3) Set IP address in Windows XP or Windows Vista/7 as it will be showed in section 3 and section 4.
4) Launch ExpertSDR2 software and push «Start».
If you have already local net with IP address not
192.168.16.ххх and you need to change IP address in
SunSDR2.
1) Connect your transceiver to PC by LAN-cable, supplied with transceiver.
2) Switch on the transceiver.
3) Set static IP address in Windows XP or Windows
Vista/7 as it will be showed in section 3 and section 4
4) Launch ExpertSDR2 software and push «Start».
5) Change IP address in SunSDR2 as it is showed in section 5.
6) Connect transceiver by LAN-cable to local net..
Now at any PC in local net ExpertSDR2 software can be launched.
Direct connection to PC via built-into transceiver WLANunit(without access point) as it is showed in Figure 2.1.
Standard 802.11n support with 150 Mbps data rate by wireless PC card is compulsory for connection. Data stream sampling rate recommended frequency from the transceiver is 39062,5 Hz in this case. This rate is set up in ExpertSDR2 software settings at Options->SDR tab.
Figure 2.1
– Direct wireless connection to PC
1) Switch on the transceiver.
2) Push «L/W» (LAN/WLAN) at the back panel of the transceiver
3) Wait till yellow led WLAN is lit on the front panel of the transceiver.
4) Connect to SunSDR2 wireless net. Make sure that connection rate on wireless net is 150 Mbps or more.
5) Launch ExpertSDR2 software and push «Start».
Connection to PC or to the net by access point as it is showed in figure 2.2.
Figure 2.2
– Connection to PC by access point (router)
Transceiver connection by wireless interface.
In wireless variant of connection there are also two ways of connection – direct connection to PC in a “point-point”
This scheme is used if you need to work with several devices by wireless connection or you have already wireless net, set according to your requirements. In this
4
Expert Electronics DUC/DDC SDR Transceivers Series case you will need to change SunSDR2 transceiver IP address.
In this scheme computer is a WLAN access point (or Wi-
Fi router) in Access Point (AP) mode, SunSDR2 WLANunit in AP Client mode.
If you have already WLAN net with IP address not
192.168.1.ххх and you need to change IP address in
SunSDR2.
1) Switch on the transceiver.
2) Connect SunSDR2 by LAN-cable.
3) Change IP address in the device as it is showed in section 5.
4) Push «L/W» (LAN/WLAN) at the back panel of the transceiver.
5) Wait till yellow led WLAN is lit on the front panel of the transceiver.
6) Put SunSDR2 Wi-Fi unit into AP Client mode.
7)
Launch ExpertSDR2 software and push «Start».
