FlexRadio Systems introduces the FLEX-5000™ family of ultra high performance Software Defined Radio transceivers. The FLEX-5000A integrates all I/Q data and hardware control over a single FireWire® (IEEE-1394) connection to a user provided computer. Sound cards and multiple cables are no longer necessary. Convenience and ease of setup are built right in!

The "workhorse" of the family is the FLEX-5000A . The same receiver and transmitter are common throughout the entire FLEX-5000 family, so no matter if you have the FLEX-5000A or the fully integrated FLEX-5000C™, you still have the same outstanding performance and capabilities.

The supplied open source software, PowerSDR, creates a powerful and flexible solution. The number of memories is limited only by the PC hard disk space.

The FLEX-5000 connects to the PC via FireWire.

My true love

FlexRadio FLEX-5000A, Headless HF/VHF Transceiver

In my opinion the Flex-5000 with the continuing support of KE9NS is about the pinnacle of SDR for 80 to 90 percent of ham radio operators. With ATU and 2nd receiver plus the UHF/VHF modules it will do it all. There are so many options and use modes that I never get bored using this rig.

Operating perimeters are infinite. Follow https://www.youtube.com/watch?v=fV_iolSf3OA W1AEX's excellent video on setting up the audio train for each mode and this baby rocks.

Happy DX-ing
