Flex Radio were kind enough to respond to Adam's report very quickly.
As expected, they indicated that there's much afoot to bring the V1 software completely up to where they want it to be for V1 performance, but also that their own internal development and testing is producing results that should be remarkable. Besides other key functionality and usability features, a lot of effort is going into important optimisations in the signal chain that should be able to really 'move the needle' in terms of the kind of parametric testing we did last weekend.
We understand that we'll be able to retest the 6700 with new software in 2 or 3 weeks that will include this next important cycle of improvements. So, I'm really looking forward to that.
