QUICK START GUIDE

Thank you for purchasing the FLEX Signature Series software
dened radio (SDR) from FlexRadio Systems. This Quick
Start Guide (QSG) will walk you through the steps for installing
the FLEX-6700, FLEX-6500 or FLEX-6300 in your operating
position and loading the SmartSDR for Windows software on
a network connected PC in preparation for your rst QSO.
Please read all included documentation before proceeding and
store this guide and all other contents, including the shipping
container, for future reference and use.

Software Defined Radios
FlexRadio Systems®
The SmartSDR™ for Windows application is the software used
to interface with the FLEX-6000 radio hardware for viewing
spectrum and controlling the radio.
Recommendations and Requirements
Minimum recommended CPU for SmartSDR for Windows is
the Intel® Core™ 2 Duo or AMD® Athlon™ 64 x2 processor.
Minimum recommended graphics processing unit (GPU) is one
that supports DirectX 10 or greater and has at least 256 MB
of graphics RAM for optimal rendering of the high resolution
spectrum displays. Please refer to the HelpDesk article "What
is important in choosing a Video Graphics Card?" (http://
helpdesk.exradio.com/hc/en-us/articles/202118528) for
additional details.
Minimum Windows and .NET Requirements
SmartSDR is a 64 and 32-bit Windows .NET Framework
application designed to operate on Windows Vista, Windows 7,
Windows 8 and later. The .NET Framework 4.0 Client Prole
is required.
The minimum version of Windows supported by SmartSDR is
Windows Vista Service Pack 2. The SmartSDR for Windows
Installer will automatically detect your current Windows version
and will notify you if it does not meet the minimum operating
system requirements. If your Windows XP PC has not been
upgraded to Windows Vista, or Windows 7 or later, you must
do so before installing SmartSDR. See minimum Windows
and .NET requirements below for obtaining the appropriate
Windows software update.
If you need to upgrade your Windows software, install it before
installing the .NET Framework 4.0 Client Prole. The easiest
method for obtaining it is to use the Windows Update service.
An optional update method is to download the update software
via the Internet directly from Microsoft using this web link:
http://www.microsoft.com/en-us/downloads
Note: this is a very large download (approximately 316 MB)
which may take over an hour to download using slower
Internet connections.
If you need to install the .NET Framework 4.0 Client Prole,
the SmartSDR for Windows Installer will automatically install it
from the SmartSDR Installation CD or attempt to download the
necessary software from the Internet if the CD is not available.
Alternately, you can download it directly from Microsoft using
this web link BEFORE installing SmartSDR for Windows.

APPLICATION ON YOUR PC
4.0 INSTALLING SMARTSDR™ FOR WINDOWSAPPLICATION ON YOUR PC

Installing the Software
If you are installing SmartSDR for Windows from the CD, place
it in your CD drive and close the drive door. The SmartSDR
software installer will automatically begin. If you are installing
SmartSDR for Windows from the installer downloaded from the
Internet, double click on the SmartSDR installer (SmartSDR_
v1.x.x_Installer.exe) to begin.
Step 1. Pre-Installation Tasks
The rst thing the SmartSDR software installer will do is
determine if your PC's operating system and installed .NET
version meets the minimum requirements. If your PC does
not have the required .NET Framework 4.0 Client Prole
software loaded, the following Setup Pre-Install screen will be
displayed.
If you see this screen, click YES to install the .NET Framework
4.0 Client Prole software or click on NO to stop installing
SmartSDR for Windows. If you are installing from the
SmartSDR for Windows CD, and selected YES, the following
screen will be displayed.
Click OK to begin the .NET Framework 4.0 Client Prole
software install or click on CANCEL to stop installing
SmartSDR for Windows.
If you choose not to install SmartSDR for Windows in order
to install the .NET Framework 4.0 Client Prole, the following
screen will be displayed.
Click on OK to open a web browser and download the .NET
Framework 4.0 Client Prole software from the Internet or
click on CANCEL to stop installing SmartSDR for Windows.

Step 3. Starting the SmartSDR for Windows Application
for the First Time
Turn on the 13.8 VDC power supply that is connected to the
FLEX-6000 Signature Series SDR. Start the FLEX-6000 by
momentarily pressing the power button.
The FLEX-6700 and FLEX-6500 SDRs have a front panel
display that initially shows the FlexRadio Systems logo and
then the text "Calibrating..." along with a green ashing LED
above the power button when booting up. The FLEX-6300
only has the green ashing LED above the power button when
booting up. Once the FLEX-6000 is ready, the LED above
the power button will be either solid green for units without a
GPSDO installed or will have an amber or blue LED, which
may be solid or ashing depending on the initialization state
of the GPSDO. The FLEX-6700 and FLEX-6500 SDRs will
display the radio model name on the front panel display.
Locate the SmartSDR application icon on the desktop as
shown below and double click on it to start SmartSDR for
Windows. (Note: your software version number may vary.)
The SmartSDR Radio Setup screen will be displayed. Right
click on your FLEX-6000 Signature Series SDR displayed on
the left hand side to select.

To TUNE the receive slice to another frequency:
1.) Click the BAND button on the left side of the spectrum
display then click the desired BAND.
2.) (PAN-EDGE-TUNING) Hover your mouse over the blue
bar (receive lter) in the panadapter window. Using the right
mouse button, click and hold the button while dragging the
slice to the desired frequency. Note that as you approach the
edge of the displayed panadapter, the spectrum display will
begin to PAN so you can see the desired frequency segment.
The tab will change from Startup to Radio as shown below.
Click on the Connect button as shown below to connect
SmartSDR for Windows to your radio.
Step 4. Operating Your FLEX-6000 Transceiver
The SmartSDR console will be displayed with one (1) High
Denition Panafall Spectrum Display and one Slice Receiver
tuned to 14.100.000 MHz as show below.

Software Defined Radios
FlexRadio Systems®
3.) (DIRECT FREQUENCY INPUT) Hover your mouse over
the Frequency numbers in the Slice Panel. Click once with
the left mouse button to highlight the frequency. Type in the
desired frequency and press ENTER. Note that you can enter
frequency in kHz or MHz directly. If the entered frequency is
beyond the displayed panadapter screen an OFF-SCREEN
indicator will be displayed on the panadapter display. Simply
double-click on the off screen indicator to re-center the
panadapter to your desired frequency.
To set the operating MODE:
