[hpsdr] PDF files reduced - on wiki

[Don AE5K]

Thanks to several on the list who did some conversion and sent the
smaller pdf files to me.  I'll pick and choose and post the smaller size
(filesize, not viewing size) on the wiki shortly.  I've also converted
them to jpg so they can be displayed in smaller size on the wiki page
directly with links still to download the pdf if the viewer wishes
better copy.  (I need a few minutes to get them posted)
