I get the point Hans and makes sense. But... tinkerers always pushing the envelope :) I was considering 17 and 20 taking into account the monoband ethos of the QCX because these bands are close. What I do not know is if this "stretch" is within the correct quadrature limits. The idea? would be 20m the primary band and 17m the secondary.
Thanks for producing things like these for us to enjoy!
