The discussions going on at Flex Radio's Email reflector site are wonderful. This is amateur community development of a new technology at its best. Only with the internet, this wonderful co-operation is now squared and cubed and is on steroids to boot. I highly recommend reading the reflector daily. The discussions on the reflector and the spirit of co-operation which they demonstrate, more than anything else, has convinced me that my next rig will be Flex Radio's SDR 1000!
