A couple of points. First, haven't you sometime worked someone on 6 meters when "the band was good"? Enormous signals from a few watts. Second, for ( a lot) more information on Part 15 regulations than you can stand to read search around under Google. FCC has them available in PDF form. I downloaded and printed them a few weeks ago (for quite a different reason) and seems to me they were over 100 pages long. Ed
