I'm now owner of two Flex-Radios.
HF/6m rig, 100W, ATU, HF software defined radio. Edirol FA-66 firewire soundsystem. (E)SSB with studio audio equipment, see Essb-setup page..
This rig was the first Flex-Radio station, sold first as a 1W version. Mine is one of the latest versions, with 100W PA and antenna tuner, and all upgrades. This is the most fun radio I own, and it wont be the last radio I buy from FlexRadio. Great support! Great software updates, and ongoing information all the time. User forum, etc.
