Yes, ARRL Labs tests are damning, though you would never realize it if 
you only read the text. When is ARRL going to assign technically 
competent authors to these reviews?

That said, Flex did issue firmware/software that is said to reduce 
keying sidebands. I've been trying to coordinate with a local 6700 owner 
to test it here.
