If you have any ideas on how to improve the FLEX-5000, please feel free to contact us, or better still, to join our email reflector (see http://kc.flex-radio.com/KnowledgebaseArticle50024.aspx). Not only is the FLEX-5000 a software defined radio;...
Page 10: Acknowledgments
Acknowledgments FlexRadio Systems could not be as successful, nor could the FLEX-5000 radio be what it is today without the many selfless contributions from our users all over the world. These contributions have spanned and continue to span improvements to our hardware and software, ranging from bug reports and feature requests to actual design and implementation of certain functionality.

(Other items may be included that are not listed above) The FLEX-5000 power cable is unterminated on one end so that you can adapt it to various DC power connectors, such as Anderson Power Poles, Banana plugs, screw terminals or spade lugs. Connect the 2 red wires to the positive terminal and the 2 black wires to the negative terminal of your power supply For the FLEX-5000A, you may need to acquire a 4-pin to 6-pin cable if using a laptop.

Page 24: Connecting To A Balanced Xlr Connector
(-) To interface this type of microphone to the FLEX-5000 a balanced XLR (female) to balanced ¼” TRS (male) cable is necessary, which should be wired as shown in Figure 5a. You can also connect audio processing equipment using a similar cable.
Page 25: Rf Ground Terminal
Connect to the single point ground system in your shack. Alternatively, if you have no single point grounding system, ground the FLEX-5000 to the metal chassis of your computer with a low impedance ground strap, such as a 1” braid or copper strip (the screws that hold the computer power supply in place make an excellent grounding point).
Page 26: Computer Speakers
Note: Do not confuse these with the internal speaker or external speakers you may have connected to the Powered Speakers jack (11), which are strictly used for receive audio by the FLEX-5000. Network Connection WARNING! Install an anti-virus protection application before connecting to networks or the Internet.

Page 35: Collecting Your Information
Make sure the FLEX-5000A is turned off (Power switch LED is not illuminated, see Figure 2 on page 3). Alternatively, disconnect the FireWire cable between your FLEX-5000 and the computer. It is also a good idea to close all other applications.
