You wonder why your post was deleted. It was just a link to your blog which, if I remember correctly, is a no-no on eham.
I brief: Flex demonstrated a Flex-6700 with Smart-SDR for the Flex-6500. The thing held by rubber-bands and in the Alpha/Beta stage (your own words) tended to crash when adding slices.
The video is not a demonstration of the Flex-6700 running Smart-SDR but a sales pitch where we do not learn anything new beside the exact price of the Flex-6500 (a little more than $4000), the price of the Flex-6700 (a little less than $8000) and a delivery date of April 2013. No exact date but one can expect April 1st.
I sincerely think your posts are a disservice to FlexRadio and will attract only the so-called Flexbashers.
