I normally print all your Manuals, Guides and Updates instructions. I find them very useful and informative. However, the newer versions of the above guides etc... are usually a re-hash of previous instructions.
Case in point, your latest release of SmartSDR Software User's Guide contains 98 pages which I printed: Comparing that version with the previous there is a difference of 14 pages. In other words version 1.1 dated 1/17/14 is only 82. But there is very little difference between the two. They have the same boiler plates about legal and copyright information; except that newer guide has 4 additional pages of legalese.
Suggestion: Let's try to save a tree and reduce the number of pages by just making available the newer or additional modifications or revisions how things work.
Since these manual/guides are not the final product ask us to update our manuals with the following pages that we will renumber. This will not only save a tree, but it will reduce the printing cost and time.
I am not a tree hugger but I can see the waste that you are producing. To many of us like to see things in writing, since we can no longer depend or keep it in our memory.
